Re: RB450G + openwrt Metarouter strange problem

remove all the unnecessary packages can bring down the crash numbers a lot. Just think what packages you need and ones you can do without. And it is not PSU related, it just requires good one, as any other device.

Thank you Janisk for your kind reply.

Do you mean the unnecessary packages in RouterOS, in OpenWRT or both?

Do you know if someone already solved the "reboot issues" by removing these unnecessary packages?
And it is not PSU related, it just requires good one, as any other device.
I normally use the TW-AC24-10 Power Supply 24V 1.0A EU.
Of course, if I deactivate the metarouter the RB is really stable.

Anyway, I would like to better understand what exactly arises the reboot issue...memory leak? cpu load? resource access collison?

Any suggestion about the amount of memory to allocate for OpenWRT metarouter? I did several tests allocating memory in the range 32-128MB. I experienced some issue by using 128MB because of the router had not enough memory to run properly.

Thanks again.

I gave up, and stopped using MetaRouter for anything. It is interesting though, that some people in this forum still recommend running stuff in MetaRouter for production use.

if i have metarouter with uptime of more than 2 weeks, and only reason why it is not higher is version updates. Then why not?

Re: RB450G + openwrt Metarouter strange problem

Thu Mar 24, 2011 7:11 pm

Unfortunately, not everyone is so lucky. Allow me to sum up my frustration with metarouter.

About two months ago I received request for recursive DNS resolver with DNSSEC validation. MikroTik is clearly not going to provide anything like that in near future, if ever. No problem, OpenWRT with Unbound running as MR would be perfect solution.
As I was new to MR and not expecting any problems, I started with installed ROS 4.5 or so (at RB450G). Router didn't stay alive for long enough to even allow me to finish the configuration. I upgraded to latest and greatest stable ROS at the time (4.16), but nothing changed. I went through forum and found this thread. Oh well, just my luck that I must get the only model that does not work well, I thought. So the resolver went to other computer that was fortunately also running 24/7.

Another case where MR would be useful came up yesterday. This time with brand new RB493G and ROS 4.17 (I understood that it was mostly RB450G with problems, so why not). And really, it was much better. Except for one strange MR lockup at the beginning (I pretended that I didn't see it), it appeared stable. There were no other problems for the whole time I was playing with it (around three hours). Then I left it running. Today I connected to host router again and oops, there was reboot by watchdog timer in the log. I talked to colleague who was sitting near the router and he said it was beeping (= rebooting) the whole day. Great. So I upgraded ROS to 5.0rc11, just to lose all hope, when first reboot came two minutes after starting MR. The only difference is that instead of "watchdog timer" the reason is now called "cause 1". The router is going to production use tomorrow, without MR of course. I don't have the nerve to explain to customer, that everything under fifty reboots a day is ok. ;)

In both cases the routers were basically idling. Just doing the role of NAT router for three users and 4 Mbits in first case. And completely nothing in second. Installed packages were near the bare minimum (advanced-tools, dhcp, ipv6, ppp, routerboard, security and system). I could probably get rid of advanced-tools and not sure about routerboard, but if I had to touch anything else, I could as well throw out the whole ROS, because those features are required. But anyway, why should the number of packages influence anything? Even if I had every single existing package installed, it should still work.
I could also blame my OpenWRT images, I mean, they were self-compiled, not tested by anyone else, it's possible that there's something wrong with them. But then again, it's not guest OS that's crashing, it's host system. I'm no virtualization expert, but if guest system in VirtualBox on my desktop computer crashed host system, I'd say there's something horribly wrong with VB. Is it any different with MR?
Workarounds like disabling watchdog timer are no solution. If I undestand it correctly, it may sometimes prevent unnecessary reboots, but can also cause the router to freeze completely, which is unacceptable.

I wish myself more luck next time. :)

I believe that is the problem - most of us could not get 2 weeks of uptime with MR running.

I too gave up on MR some time ago. I ended up using a $50 Open-Mesh router reflashed with Backfire to do a simple network monitoring task.

MR could have easily done this task, but it was not stable. The customers could not afford reboots on the main router.

have any of you RB433AH available to try these configurations, just to see if there is a difference.

Also, if possible, can any of you try to disable watchdog on host and run some monitoring software inside metarouter (with virtual ethernet not had port attached to connect host/guest)

Re: RB450G + openwrt Metarouter strange problem

Mon Apr 04, 2011 1:00 am

I can't do much. I don't have any RB433x. Currently I can play only with one remote RB450G, but I must be very careful. Reboots are acceptable outside of busy hours, lockups are not (so no playing with watchdog). Currently it still has ROS 4.16, but this week I should be able to get it upgraded to ROS 5.0.

I can share my OpenWRT images if it might help. One is trunk build from half of december and the other one is from trunk about week old. I have .config for second one. I get the same results with both.

Steps to reproduce:
- import image with 32MB RAM and unlimited disk
- don't add any network interface
- start MR
- open console
- run top in console

The console freezes in matter of seconds, minutes at most. Sometimes even before it gets to command prompt. Reboot by watchdog timer follows shortly after. Automatic Supout is enabled in Watchdog, but doesn't produce anything.

I'm have the same problem on a RG450G did try 4.17 then 5.0rc11 and now 5.0 stable, still reboots. And also writes the same in the logs as you have.
Nice to hear, others having this problem :)

Thank you for your answer! Disabling unneeded packages does indeed seem to help.

I'm running ROS 4.16 on a RB450G. The OpenWRT inside metarouter is r18199 as provided by nik247 in the "Metarouter images" thread.

Like you suggested I disabled all ROS packages except routeros-mipsbe, system, and routerboard. This increased the stability greatly, but the router still rebooted ~1-2 times/day with a reference to the watchdog timer. When I stress tested the VM with an infinite loop bash script it was active for about 4hrs at maximum CPU load. Previously that would have killed the VM within minutes.

I have now disabled watchdog and my OpenWRT uptime is at 14hrs and counting (there is no significant load on the system other than a httpd serving some continuously updating cgi scripts for monitoring).

Last time I was tinkering with this problem I remember disabling watchdog led to (temporary) router lockups instead of the reboots. As I'm not sure this will show in the logs of either the RB or in OpenWRT I will write a small ping script to see whether the VM stays up or if the "uptime" in OpenWRT is only how long the VM thinks it's been up.

Is there any other way of detecting these lockups? I am rather proficient on the linux side of things but not so much with ROS, so I apologise if this is a matter of simply "reading the logs."

Good to see the problem is being worked on.

Re: RB450G + openwrt Metarouter strange problem

idea is to monitor host 450G from outside and from guest, to see freezes happen internally too, as it is not clear yet. that is, if it is possible to reaech host system from guest when from outside there are no response (6second freeze as i see them)

My uptime in OpenWRT is now 20 hours with heavy load (infinite loop bash script) for at least 5 of those hours. There has been one freeze lasting about 10 minutes, with the host and guest becoming responsive at the same time and without anything in the error logs of either. There has also been two instances of the guest not responding for a very short time (less than 10 seconds), I guess that could be the kind if 6 second freeze you refer to.

I will tweak my monitor script to run inside the guest and monitor the host. Will post results once I have them.

Re: RB450G + openwrt Metarouter strange problem

Mon Apr 11, 2011 5:26 pm

I don't know if this helps but...

I noticed a router w/ metarouter that was rebooting like crazy. I logged in when the metarouter had locked up (but router was still responding). Before it rebooted I looked at the metarouter through the virtual console. It spit out a bunch of strange information (and rebooted shortly after).

Im get caught too, by buing RB450G for virtualization.

So,.... please, can you publish list of 100% compatible routerboards for virtualization? I had to decide witch RB i had to buy for it.

What routerboards actually work consistently with metarouter? Any model I have ever tried it on is unstable.

hi, as i see i am next person having this problem :D

i bought RB450G in january 2011

virtualized openwrt
tried 5 images all with same problems - reboot of entire RB (by watchdog) or openwrt freezes
tried routeros v4.17, v5.5 - doesnt help
tried at 400MHz and 680MHz - doesnt help
cpu, ram, flash utilization of RB is low (also in openwrt)
tried to make simple config (acting as switch) - doesnt help
tried to disable most packages - help a little :)
tried many combinations of ram and flash alocation for openwrt - doesnt affect uptime
tried 24v/0.8a power supply and 24/1a POE - same behavior
out of ideas :D
maybe somebody should try to compile another OS than openwrt

i have running RB433AH, RB1000, RB800 on my table that are not rebooting. All of them have at least one metarouter guest running that is RouterOS. Also, all have 32MB of RAM assigned, since 16MB with all packages installed is not enough.

I had to move to RB800 too from R450G - i needed to run two metarouters - RouterOS , RB450G keeps rebooting after 15 - 20 mins, no autosupout or any other output. Tryed V4.17 and few V5.x before 5.3

Are your test routerboards doing anything or just sitting there? I think it has something to do with stress on them that makes them reboot because I see a lot of variation in the amount of time it takes for them to reboot. I tried the same settings as you have on a 433AH and still have the same problems (I have even tried with all unnecessary packages disabled also).

hi,
i own rb450g
do you even assume what should cause this problem?
i am sure it is NOT psu related
i have already tried 24V/0.8A (20W) and 19V/4.74A (90W) psu and 24V/1A (24W) POE - uptime was never longer than 10-15 minutes (whole routeros restart or openwrt "freezes")
also i read here about disabling all unnecessary packages
i left enabled only "system" and "routerboard" (that 2 cant be disabled)
the uptime raises from 10-15 minutes to 1 hour
i tried at least 4 different openwrt images and uptimes was almost same
all of this tried with ROS4.17 then ROS5.5
i need at least 2 weeks
so again, do you even assume what should cause this problem?
is it HW or SW related?
if you have some ideas, i can test or send anything you want

Re: RB450G + openwrt Metarouter strange problem

Fri Jul 22, 2011 10:57 am

if resources are available (router has few % of cpu left and there is ram) i have seen no difference in reboot frequency with or without load. Even simple usage patterns did not cause it to reboot more.

Reboots usually where done by watchdog, disabling it - revealed that router freezes from time to time.

At the moment idea is that problem is software related, but has to be tested on different hardware (like RB433AH - same cpu, decent amount of RAM). And that problem is, that something does not like MetaROUTER being ran on the RB450G.

I believe it is software related. I have the same problems on 433AH as 450g.

Also, I have noticed that routers with worse connections (higher packet loss) seem to reboot more frequently.

watchdog may reboot your router if it does not get the time-slice to do the "check if I am alive" and that is not a problem, since router is loaded 100% and for some long time, meaning load on the router is too big in current configuration and should be looked at and optimised if possible.

You should check with router that is not fully loaded (like 80% - 95 % load) and you should see that RB433AH will stop rebooting.

Last week i removed RB433AH that where running old version of RouterOS with several MetaROUTER guests running with 8 month uptime. Also, there might be other problems that causes reboots in your case, since i ran minimal feature set on the board to ensure that all the problems are caused by metarouter on the router.

something new?
still having this problem, and metarouter was only reason why i didnt bought ubiquiti routerstation pro
it is possible to return this device to reseller, because metarouter is key feature for me, and it is not working?

It sounds to me like Mikrotik is going to deny the existence of this problem. Then they don't have to deal with it!

you should learn to read. Problem is known and admitted long time ago. Since there is no reliable way to reproduce and causes are not known problem still persist. RB540G has the problem, while RB433AH with the same CPU does not. Only dependency for MetaROUTER is the CPU.

If someone wants to return the router only because it does not have working feature, he has to contact one who have sold it and make arrangements.

to sum it all up on RB450G:
1) choose other board, even it is MIPSBE
2) install less packages (minimal set for the task)
3) disable watchdog, if lucky, you will encounter short freezes, and everything will continue to work.

Your experience may very. Situation can change after reboot.

Re: RB450G + openwrt Metarouter strange problem

Tue Sep 13, 2011 1:39 pm

as far as i have tested eventually all RB450G have frozen. As devs are explaining, only parts that metarouter uses are CPU and RAM. Testing RAM and CPU under load did not show any problems with the parts. So no, I do not know where is the problem. If i knew, i could point devs and that would have been fixed long long long time ago.

What is written in this thread that some RB450G can freeze with larger interval some with shorter, and that interval can change.

Re: RB450G + openwrt Metarouter strange problem

Tue Sep 13, 2011 6:12 pm

Ever since i got RB450G i had the metarouter problem... And since then i've been trying to find the problem.
Now my testing show's that it is a mr-network problem.

If i add 8 RouterOS metarouter's with no network connection, it runs fine for weeks, not even a single problem.
But if i add a interface (dynamic or static) to just one of the metarouter's, i starts to freak out and get unstable!
And then i can't connect to the metarouter(s) or the RB450G even not on the serial port!
Then after some time (all from a few min to hours/days) it comes back on the network and serial, then i can connect and disable the interface, then it runs fine for weeks again...


Now does who have a RB450G, can i get you to try this?
Clean install on RB450G and then add 8 Metarouters with RouterOS (no network interface) and let something like the dude monitor it (just to see if ping works).
Then let it run for a week or two.
If it still runs with no problems, try and add just one interface to a metarouter.
Then let it run for as long as it can (or just up to 1-2 weeks), then write here, with your experience.

Re: RB450G + openwrt Metarouter strange problem

after reading this in the morning i set up RB450G with metarouter configured as follows:
/metarouter add name=mr1 memory=32
/interface virtual-ethernet add
/metarouter interface add virtual-machine=mr1 type=static static-interface=ether5
/metarouter interface add virtual-machine=mr1 type=static static-interface=ether1
connected ether5 with ether1 using wire.

will leave for some time.

edit: it was not crashing with metarouter running w/o interfaces for some time w/o crashing as described. Also, i have OSPF running on the router.

I don't use OSPF on it, just a clean install and setup with metarouter.
But i think it is funny that i on my RB450G can replicate this problem time after time and even after a netinstall...
Maybe it is a faulty board then?
The only thing i wanted it to do, was run metarouters, but stacking RB750 seems to be a better idea...

I've come to the same conclusion...
The 256MB of RAM in the RB450G are a total waste of ressources(and money) without Metarouter.

running metarouter on board that before was the worst candidate if talking about stability of MetaROUTER, so the stats:

changes. before router was set up it had bad caps (the green ones that where bulged up) changed. after that nothing has been done. time difference in host and guest uptime is time to make printouts and pasting them here and doing some rearranging.

Janis,

we have 3 brand new 450G in our test-setup, ALL of them are practically useless regarding stability.

Re: RB450G + openwrt Metarouter strange problem

Tue Sep 27, 2011 3:47 pm

You can't seriously try to tell us that there's nothing wrong.
all i did was report back to persons interested on how the test is going. Obviously - bad. Problem did not manifest it self, but it should have done that. At least i was hoping for that to happen.

Maybe someone could try to check this:
[admin@450G-2] /interface ethernet switch> print 
Flags: I - invalid 
 #   NAME                        TYPE         MIRROR-SOURCE                      MIRROR-TARGET                      SWITCH-ALL-PORTS
 0   switch1                     Atheros-8316 none                               none                               yes             

All i need is to make precise scenario to recreate the problem in relatively short time.

Well in my case, the setting was set to switch-all-ports NO. But I thought you could see this from the last suppouts I sent a while ago.
I will do another test as time allows.

trying to have more open conversation, so if someone who wants to help out with same problem could fill in. I am unhappy with the testing results - problem is - no scenario on how to recreate it hence, nothing useful to report to devs. It just starts to freeze when it gets "bad mood" or something.

Janis, lets see if I got this right.
1.) You test with a RB450G.
2.) You have setup your switch to switch all ports.
3.) It runs stable for you.

What if you change switch all ports to no?
In my case problems startet right away.

set to switch-all-ports=no lets wait for the results.

if you set to switch all ports=yes, do the problem stop for you?

edit: left running and sending ping requests to the router. will leave it for the night.

I started a quick test at my live router.
I added one Metarouter with one local dynamic interface.
ROS 5.6
Uptime at the moment 5w3d4h53m30s.
I will report back in tomorrow.

EDIT: switch all ports was set to no, I changed it to yes.

Did just change mine from "yes" to "no" and has been running fine for about 5mins now (4½min longer than last test).
And the dude is on the case :)

*EDIT* Now 2hours later and it still runs fine... i will let it run for a day or two (maybe a week), then try the old settings and see if it fails again.

Mine did run for 7hours! then the dude told me that is was down, then 2mins later it was up again.
5mins after it came up again, it went down for about 5mins and came up.
And has now been running for 1½ hours with no downtime.

2 Metarouters, just pinging to the host, stable since yesterday 15:00 UTC.
Each Metarouter doesn't show a single loss, max ping rtt 13-14ms.
/metarouter

I will change the setup now, to using an externel ethernet port.

Re: RB450G + openwrt Metarouter strange problem

Wed Sep 28, 2011 11:34 am

Conclusion by now: As both barkas and QpoX both have crashes regardless the switch switch-all-ports setting, I think we can rule that out.
Significant difference between my setup and barkas setup is, that my Metarouter does nothing more than just pinging over one interface, and barkas does full MPLS tests.
Janis maybe you could do some MPLS tests between Metarouter and host or some load tests using ipsec? Anything that touches ethernet/ip stacks and/or produces some load...

Re: RB450G + openwrt Metarouter strange problem

Wed Sep 28, 2011 2:19 pm

i have had router with metarouter freeze up without MPLS. I have one suspect that i am testing out, it crashed once without debug MetaROUTER, now router sits at devs with debug version of MetaROUTER. That is thanks to new board that has similar structure as RB450G where debug mode or MetaROUTER can be monitored (it cannot be done or RB450G).

Fingers crossed it crashes again.

some details - Router was just idling same as metarouter, and then it rebooted.

Ok, my new Metarouter test crashed after about 3 hours.

Short sketch of the config:
1 Metarouter, 32MB RAM&Disk
2 Virtual Interfaces, one dynamic as bridge port, one static to ether2.
Pinging from Metarouter to host.
Pinging from another System connected at ether2 to Metarouter.
Only things configured in Metarouter where one IP per interface and System name.

Packages:
/system package print
Flags: X - disabled
 #   NAME                    VERSION                    SCHEDULED

 1 X ipv6                    5.6
 2   system                  5.6
 3   mpls                    5.6
 4 X hotspot                 5.6
 5 X wireless                5.6
 6   routerboard             5.6

10   routing                 5.6
11   dhcp                    5.6
12   ntp                     5.6
Switch all ports ist still set to yes.

I'am sorry, but that is about all I can supply as tests by now.

Your devs forgot to include the AR7116 in the JTAG scan chain on the RB450G? ;)

Here is my final log of this test... so it's no working solution...
Now all metarouter interfaces have been disabled again, and it runs stable, but no network to the virtual machines.

I have, yet again, a useful purpose for a metarouter.

I guess you only could try yourself, there is extremely less feedback on Metarouters altogether.
And, without wanting to bash MT, there seems to be no clear understanding of the cause on MIPSBE, so every MIPSBE based board should be viewed as affected. Even a small software update might tip those boards over the edge.

If people are asking for progress and we don't get any answer, why would you characterize my comments as spam?

@xdemon: I've never reached 24 hours uptime on 750GL with MetaROUTER activated (with OpenWRT guest). I don't know about ROS guest, didn't test. And btw, the VM was doing very light DNS traffic for home LAN.

I don't think it's traffic related. I don't really use mine except for testing now and then and it reboots often enough.

unfortunately it is all I can disclose. and even then some of info is just a guess :(

so, there are reports of metarouter hanging on RB450G and RB493G. Anyone with RB435G or RB411AH can try metarouter on it?

for me RB433AH does not crash. Now stuck with RB450G that does not reboot :?

I can only repeat and clarify what I said in earlier posts:

The whole MIPSBE series should be considered unusable in combination with Metarouter.
Especially with the information available from MT and the fact that they aren't capable of fixing this problem in such a long time.

@MT:
This is not intended as pun, just as a warning to everyone planing on using Metarouter on MIPSBE based MT boards.
And don't start repeating that Metarouter is stable on "some" MIPSBE boards, this is just plain luck and might change with every change/release you make.

It doesn't stable even with routeros virtualized. Crashed after 10 mins with router reboot. metarouter-fs used 40-80% of cpu first 3 mins. I have autosupout.rif file, but i can't find enything useful in it.

UPD: looks like it working after reboot.

Is this problem isolated to MIPSBE or all BE processors? LE architectures do not have the problem?

If so, those are huge clues.

MIPSLE boards do not support metarouter, hence - they do not suffer from this problem. As far as i know various RB4XXG models do suffer from this problem (RB493G, RB450G, RB435G). Never seen this problem on RB433AH and similar.

And yes, this could have an influence but at a point where it's already to late out of a developers perspective.

le, is x86 and mipsle, both of the does not have MetaROUTER.

and this problem is not out of devs perspective. Just there is not a reliable way to reproduce it. As sometimes something starts to happen after 2 weeks other time, restarts happen once in 10 minutes.

Interesting. I did not know le, and in particular x86, doesn't support metarouter! This saves me a hard lesson.

on x86 you go KVM to virtualize.

Can anyone run 'while true;do dmesg -c;done' and see what happens? And please leave that command running in openwrt (for example in background)

And yes, there is something i discovered in process of testing:

1) netconsole. There is no error logs sent via network - only standart boot data.
2) There is no crashdumps in openwrt machine. Basically everything is okay with openwrt.
3) i tried watching dmesg, and there is no error messages too.
4) Mikrotik MetaRouter (with RouterOS machine) sometimes hangs too.
5) And... sometimes reboots of router (physical, not virtual one)

So... this is 100% RouterOS fault. I sent supout file to mikrotik.

P.S. if we only had access to more verbose logs...

Some interesting info. I enabled writing debug logs to disk, and tried to catch some messages.

Of course i haven't found any useful info, but...

There were no virtual machine freezes
Instead, router crashes hard. I always saw that first virtual machine freezes, and then router crashes (if you do not disable VM via /metarouter _before_ router crashes - if you will be fast and disable VM router will not crash)
I tried that, well, somewhere around 10 times. VM _do not freeze_. Router crashes anyway...

Maybe that somehow related to filesystem?

I am just using metarouter so I can load OpenVPN into OpenWRT to use UDP as the transport protocol. If MT could just add the UDP option for OpenVPN instead of only TCP I bet it would solve some problems out there.

I wouldn't hold my breath.
Maybe a x86 Board like Soekris net6501 with KVM will be more usable; I didn't try.
I just use MikroTik/ROS for testing and home usage and gave up all planned and realized productive installations.

Re: RB450G + openwrt Metarouter strange problem

Thu Feb 02, 2012 6:08 am

Perhaps the problem is really in miscalculations in the design of power converters on the routerboard 450G. With a standard external power supply DVE DSA-20P-20 24V/0.8A router, when running metarouter, was unstable and often restart at arbitrary times, even in idle mode. ROS 3x, 4x, 5x - no difference. However, with the simple old transformer power supply 12V/0.5A router works fine for more than a day, with a test load in the form of Ping Speed between the router and metarouter (average 163 Mbps at a reduced up to 400 MHz cpu clock).
By the way, lowering the CPU clock from 680 MHz to 400 MHz did not affect the instability.
When using low voltage power supply, became less warm coils and capacitors in both the power converters to 3.3V on routerboard, which is an indirect proof of engineering miscalculation. And stronger heated coil, which supplies the switch chip and memory. In this scheme fits the fact, that router is a bit more stable in the mode "switch-all-ports=no".
IMHO, the designers of this model were to use a more powerful power converter, similar to that used in RB433x.
Another is the idea of replacing the electrolytic capacitors on the solid polymer capacitors. It is not excluded, that this may also solve the problem.

ps Forgive me my nice Google English :)

the frequency of reboots of the board is not connected to PSU in any way, of course, board has to have enough resources. It was tested at full CPU load.

I guess you only could try yourself, there is extremely less feedback on Metarouters altogether.
And, without wanting to bash MT, there seems to be no clear understanding of the cause on MIPSBE, so every MIPSBE based board should be viewed as affected. Even a small software update might tip those boards over the edge.
It's not just the MIPSBE, I have the same behavior with PPC platform, RB1000 and RB1100AH tested.
My bet is that the MetaROUTER software is unstable.
Have anyone configured the guest interfaces in dynamic mode only?
I'm wondering if the setup of static interfaces is not correctly configured in the underlaying Linux kernel.
I was convinced that static interfaces is a HW bypass directly to the guest, but I don't think so any more.

Can you elaborate on this? What specific configuration changes resolve MR issues on PPC routers?
Is there a wiki of sorts?

I had given up on Metarouter until mipsbe becomes stable. But if ppc is stable....

I'm installing an RB1100AH next week and could use MR for lots of things - if ppc Metrouter is stable.

Tweaking your configuration until the system runs stable isn't a solution.
At best that's a workarround and nothing you let your customers play with.
Do you have any experience of ROS x86 KVM stability?
No. I would like to think that this configuration might be usable, but I am unwilling to take the risk.

I'm starting to suspect that whoever wrote the MR code isn't longer working for MikroTik. So MR might be considered an abandoned technology.

Totally agree on this.
As long there aren't any description and manuals provided with confirmed and tested configurations, the MR aren't usefull.
No. I would like to think that this configuration might be usable, but I am unwilling to take the risk.
I will setup an x86 appliance for heavy tests the KVM.
I'm going to test it exactly same way as I'm testing the MR

Re: RB450G + openwrt Metarouter strange problem

good, waiting for your results.
Some results, or to be more precise, different config settings between MetaROUTER and KVM.
Janis! correct me if I'm wrong about my assumptions and conclusions.

I'm trying to understand the different configurations based on my Linux knowledge and how-to configuring tun/tap, vlan and bridges in Linux OS.
When creating static interfaces in MetaROUTER, you can select physical interfaces like Ether1.
The selection list on KVM show only the interfaces already added as Virtual Ethernet interfaces. (/interface virtual-ethernet)

In MR, if I use a physical (not configured on the host) interface in a guest and add VLAN on that interface on the guest, the VLANs works.

To do the same thing in KVM I need to create a bridge with a tap interface and the physical interface I want to bind it to.
The tap interface is the interface that is attached to the guest.

If I create the same configuration in MR with a bridge between a physical and virtual and the vif attached to the guest, all interfaces stops responding.
I have arp in the guest and the bridge host table looks alright, but the guest is not responding.
The difference between the configuration of virtual ethernet interfaces, is that in KVM you can assign MAC-address on both host and guest side, but not in MR.
If I, in MR, change from static to dynamic and assign the interface to the same bridge it all starts working again. And now, it assigns a MAC-address on the host side.

From Winbox (2.2.18) I can add and view Virtual Ethernet interfaces in KVM, but not in MR.

Is the MetaROUTER paravirtualization or just a software on the hosts that emulates a ROS?

More to come.....

this one is interesting, now if you could give full configuration of the "same" configuration would be nice (to avoid confusions. That is mipsbe router?)

when you assign physical interface to MR tap interface is tapped into the physical interface well before a lot of stuff that works with packets in RouterOS. There are some services that can get packets on the host from that interface, but could not work around that. In KVM that is not possible. When transmit happens from MR packets are put into interface send buffer and interface just sends them out (as it usually does, as interface only concern is OSI Layer1)

MetaROUTER is not just ROS emulation, as it is possible to have OpenWRT and, as some reports say, debian running as guests. Similar to KVM, MR requires CPU virtualization support.

RouterBOARD routers will not have Virtual Ethernet tab, instead use filtering to filter out virtual interfaces if you have a lot of interfaces on the router.

Maybe ... However, with a 12 volt transformer PSU 450G uptime for over 5 days. However, I did not banished tests this time, but with a 24 volt PSU uptime does not exceed several hours even under no load.

i have ability to set PSU voltage to value i desire in range where RB450G is working and change of that did not change stability of the setup. Maybe you could list what amperage you get at what voltage from these PSUs?

edit: check in what condition are your capacitors.

OpenWRT is heavily patched to run on MetaRouter. I seriously doubt you can get anything to run without heavy modifications, e.g. full paravirtualization.

Are you sure MetaRouter does hardware virtualization on MIPS?

Transformer PSU used DVE DV-1250UP 12V/0.5A
450G when operating this PSU at idle consumes 0.36A with running Metarouter and 0.31A with a stopped Metarouter

The problem with the electrolitic capacitors Suxxon me know :) see here and here. These capacitors from the main DC/DC converter (7...28V to 3.3V) were replaced in advance by electrolitic Nichicon 1000.0/6.3V, combined with a faulty motherboard. The input capacitor 330.0/35V I have not replaced, he works in a relatively comfortable conditions.

In the plans to test the stability of pulsed PSU Powertron PA1008-2DE 12V/0.5A. And how will his free time, to measure the waveform at several control points on the power rails. It also plans after checking power supplies want to replace electrolytic capacitors with polymeric and verify with the standard 24V PSU.

p.s. There is also a possibility that could fail PoE switch logic, such as short-term switch, which is why just lost power. Unfortunately, I have no design scheme to say this objectively.

with all links active and with CPU loaded 0.5A @12V can be too short. You could be lucky with any other PSU. But good to hear that you have it running for 5 days now.

No, only four active link and a regular on an Internet surfing. But even in this mode with 24V PSU uptime does not exceed several hours.
"Native" 24V PSU tried two things - with both equally unstable.
p.s. It is still checking PSU. Ahead - a study with an oscilloscope. ))

Today I began to test Metarouter on RB493G platform, ROS5.12

I'm runing defult configuration on host router and two MR - one with ROS 5.12, the other with DDWRT images from this manual http://wiki.mikrotik.com/wiki/Manual:Metarouter.

Every router has one static and one dynamic port. Thats all.
I'v got 3 crashes ( with systems reboot) with interval from 15 to 90 minutes.
I see that RB45x and RB49x devices not sutable for MR feature about 3 years :shock:

Could anybody answere below question?

1. Does this problem deal with only DDWRT or ROS Virtual machine too?
2. How it works on PPC architecture?
3. What device is the most stable for runing MR wit ROS Image? How long uptime they have?

As you can read from my previous posts, the MR aren't useful in any platform.
If you want virtualization in ROS, go for x86 platform and run KVM (Qemu) guests.
