I tried a P2V migration last week and here might be a better spot to document the results. I have an aging physical host running Windows 2003 Server and I want to P2V that host in to a libvirt VM. The physical host uses a Compaq Smart Array 532 Controller with a Compaq Logical Volume SCSI disk device. The logical volume is a RAID 5 set.
I first tried using the new virt-p2v approach, but haven't been successful. So I tried doing it the old-fashioned way. On a RHEL 6.1 host, I built a libvirt Windows 2003 VM from scratch using a virtio system drive. Then, on the physical host, I ran ntbackup and backed up all the system drive files to a network share viewable from my newly provisioned VM. I also backed up the system state. From the 2003 VM, I restored the system drive files and system state and rebooted. When rebooting, the VM flashes a couple of POST SeaBIOS lines, then the console window goes black. No BSOD, just black. Virt-manager shows the VM is still powered on, but the console window just sits there, black, until I force the VM to power off. I tried pressing F8 to see if I could get to a Windows boot menu, but this never worked. I have a hunch something is going on with the new system virtual drive and the driver for the old system drive. I can boot the VM from a virtual CD and launch the Windows recovery console, and from there I can see the Windows installation. The login uses the new password, so I think the ntbackup - restores did their jobs. I tried a fixboot and fixmbr, but neither of these did any good. I tried another ntbackup - restore, this time using an IDE system drive in my VM (the restore took 50 percent more time than with virtio), but this also made no difference. I ended up re-enabling the NIC on the physical host again and now I'm trying to come up with a plan C. Are there any other ideas I'm not thinking of? Thanks - Greg Scott
