I seem to be having a problem where I have created a 20GB xen image of centos 5.2 on my centos 5.2 host. It works perfectly on the host and is setup and ready to be put into action on my RouterOS machine. However I would like to know what would be the best way to copy across the image from the hout to the router? I have gone about it the long on tedious way by first copying it to my windows machine from the host using WinSCP and then to thr MT router again using WinSCP but once it gets to the 2GB mark it stops the copying with an unknown error.
Am I missing something here? I am still relatively new to the virtualization scene but feel I am making big steps everyday. Albeit that this (what I feel should be a rather small step) is now throwing a bit of a spanner in the works.
Maybe 2gb is a file system limit? Have you tried using the fetch command from routerOS to grab the file from your CentOS host? Put the file somewhere in an FTP path and pull it. If that stops at 2gb also, then it’s a filesystem, limit.
Or maybe this is not what you are trying to do at all? I’m confused over your setup. Is the machine running RouterOS, running it in a virtual session, and you want to run CentOS virtually as well? Maybe if you explain the setup, and what you are trying to do, then you might get the answer you need. Remember this is Mikrotik forum, and setting up CentOS would be a frowned upon topic here
Thank you for the response Jimbo, and too true, I should have explained the setup.
I am running RouterOS on a PC with the XEN package installed and then have created a centos image which I want to run virtually on the ROS box which will run the mailserver side of things. I have done it with a 2GB iamge no problem, so my image creating and setting up is not the problem, just when I increase the image size that needs to be copied across.
I have posted before regarding this problem I am experiencing and was told that it can be done and has been done with 10GB & 20Gb images and could be my hardware causing the limit, however I don’t understand how it could be my hardware.
Like I say, I am still new to this so learning every day and it could just be me. I hope I have explained properly.
Have you had a look at http://wiki.mikrotik.com/wiki/Xen specifically, the section entitled Example: Preparing Centos 5.1 Image Maybe you can adjust the default setting of 2gb, to 20gb and see if it will install ok that way? I know thats not exactly what your trying to solve, but if it works, it would get you up and running
What you’re trying to do should be possible. I have an almost identical setup - PC with 80gb HDD running MT3.23. My Xen VM’s have two images (two virtual drives each) one being 20gb and the other 30gb. I didn’t try loading with SCP, but used FTP instead and worked fine - just took a long time!
Sorry I can’t offer much advice, but can at least confirm it does work for my setup. One thought was that maybe your SCP client has a 2gb limit.
You should be able to send it right from the centos machine using scp to the destination, without an intermediate windows system for copying the files.
