xen+x86 when?

[dorijan]

Hi…
I suppose nobody have magic ball to see when xen will be working on x86, but I was wondering is it even in plans to make this work? thank you

My guess is probably not. However, there’s a KVM package in v4.x that should replace Xen for virtualization. It requires your CPU to support hardware virtualization though.

I’m trying to use my Xen vm machine on v4.1 but no success which perfectly runs on v3.22. Only thing seems to be inappropriate is the main memory parameter under the xen menu which i can set but os is not getting aware of it.

Do you guys have a plan to fix this issue so we can use our existing stuff with the new router os versions? We don’t have a kvm capable cpu so kvm paclkage is not an option.

Thanks
Gokalp

What image are you using in 3.22?
Can you post more info about the setup(export setting etc)?
BIG THX!

This is a confirmed problem. There appears no problems with images, but rather the Xen package itself.
This problem started in v3.23 and still isn’t fixed in v4.2. Email support [at] mikrotik [dot] com and ask them to fix it.

IMO, you did everything right, tombrdfrd66, but there’s a problem with memory-for-main xen parameter in RouterOS versions 3.23 and 3.24 - seems like it’s simply ignored.

I was using centos xen image with 3.22 and noticed it didn’t work any more after upgrade to 3.23 (failed-to-setup-vm status). It was reporting full physical memory size for main and ignored any setting I entered for memory limit in xen parameters - and the same thing happens with 3.24, too. After downgrade back to 3.22, everything is back to normal.

So it’s either waiting for a fix from MT or back to good ole 3.22… that is, if you need xen.

im using router os 3.22 with xen.
i have created ROS image, its up & running.
but im unable to Shutdown & reboot the child OS loaded in xen. also im unable to restore the settings from backup file in child OS.
my settings are
name=“EverNew” disk-images=hda:EverNew.img initrd=“” kernel=“”
kernel-cmdline=“” cpu-count=2 memory=64MiB weight=256
console-telnet-port=2323 host-shutdown-action=shutdown state=running

i did almost everything to solve it myself. plz advise something

[janisk]

due to problems with XEN at the time - XEN support was removed from RouterOS in v.4.4

Current RotuerOS released version is 5.12 and you should use KVM to virtualize guests.

[jp1]

You can still use another linux distribution as the xen “hypervisor” and routeros as virtual machines.

You can still use another linux distribution as the xen “hypervisor” and routeros as virtual machines.

And pay for a license for each one - possibly not such a good idea.

[wpeople]

if you have a ‘master’ image with a basic ROS-x86 install, and copy to different image files, it will work.
However i don’t know if it violates the EULA or not.
(Running several virtual router on mikrotik “hypervisor” is allowed - so running several virtual routers on different “hypervisor” maybe the same

RouterOS license implies that each running copy of RouterOS has to be licensed.

[wpeople]

hmm. so running ROS in ROS’s metarouter means different copies? (and needs different licenses?)

[janisk]

RouterOS as MetaROUTER guest will not require license key. RouterOS installed as guest in KVM or whatever virtualization - will.

[lahoras]

Is very inportant this question, becouse at the moment, as metarouter only run on rb1000 or rb1100 and this are discuontinued, in new line rb1100ah and rb1100ahx2 dosen’t run, only is possible use on rb450g and is not very realiable, too many users can confusind and try virtualization on KVM, beliving that is same as metarouter.

[janisk]

it works on rb1100ah same as on rb1100, just have to use newest version of RouterOS where problem encountered on rb1100ah has been resolved.

[lahoras]

Then the problem dosen’t memory storage?, how many metarouters can run simultaneously on rb1100AH?, can you help me with this?, I have purchased a RB1100AHx2 and is not support metarouter, is incredible perfomance with respect RB1100.

rb1100AHx2 does not support MetaROUTER, and on any other metaroutere out there you can run 8 guests as per manual here:
