Hi,

I guess this can be a generic question as well...

I have several para-virtualized VM's under XenServer, and I'd like to move them to KVM. Xen doesn't boot the kernel in the image, in fact, I'm not sure the XenServer VM even has a bootloader. I've tried Clonezilla to move the VM's, and it fails to boot under KVM.

Does anyone have a howto on moving from XenServer to Proxmox?

Thanks,
Gerald

Hi, I have done it with this script xenmigrate.py
http://jolokianetworks.com/70Knowle...te.py/Xenmigrate.py_import_and_export_example

It's exporting xenserver disk to .raw file.

For linux vms, just install grub and a kernel before doing the migration.
 
The problem is two-ways:
1) XEN uses an image per partition while KVM expects an image per disk.
2) XEN boots the VM with an off-VM kernel or more correctly a special XEN tailored boot method.

To fix these problems you need to do the following:
1) Create a VM image the size of the combined partition images
2) Partition this VM image so that each partition matches a ditto XEN image
3) Before transformation remember to install the kernel, udev, grub and acpid in the running XEN VM
4) Shutdown the XEM VM
5) Make a bit-wise copy from XEN-partitions to the KVM image using dd
