Problem booting Microsoft Windows KVM virtual machine

Hi all,
I'm having problems with a vm's startup, I cloned the entire disk of a Windows 2000 with dd on a drbd device, that disk was configured with two partitions. I'm able to see all the partitions contents by using kpartx and mount them:

# kpartx -l /dev/drbd0
drbd0p1 : 0 202751488 /dev/drbd0 32
drbd0p2 : 0 285567360 /dev/drbd0 202751520

The problem is that when i try to startup the vm with virsh it hangs on boot by saying "error on operating system load". Here are the details and the vm conf:

# cat /etc/libvirt/qemu/vm-sophos.xml

      <address type='pci' domain='0x0000' bus='0x00' slot='0x04'

    </memballoon>
  </devices>
</domain>

Note that I've tried to change "source file" parameter with /dev/dm-0p1, /dev/drbd0p1, but virsh don't let me boot the machine saying it is unable to find the disk.

The kvm command launched by virsh is this one:

/usr/bin/kvm -S -M pc-0.12 -cpu qemu32 -enable-kvm -m 256 -smp 1,sockets=1,cores=1,threads=1 -name vm-sophos -uuid 213a464c-73ad-8122-3647-7ff6b78d9e07 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/vm-sophos.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -boot dc -drive file=/dev/drbd0,if=none,id=drive-ide0-0-0,boot=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -device rtl8139,vlan=0,id=net0,mac=52:54:00:15:0d:68,bus=pci.0,addr=0x3 -net tap,fd=44,vlan=0,name=hostnet0 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 0.0.0.0:0 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4

I'd also followed the steps described here:

http://www.brandonturner.net/blog/2010/01/convert-windows-to-xen-guest/

to use fixmbr and the operation succeed, but the error on the vm is still the same.

What should else i check?

Hi,

Before you begin, prepare the running w2k to use ide disk (and boot on KVM with ide disks)
For w2k I followed this link (solution 2 worked for me): http://www.motherboard.windowsreinstall.com/problems.htm

And I am using clonezilla live cd´s to do cloning jobs, for me this is a fast and convenient way.
Also, take a look on our http://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE, including some hints for several sceanrios.

Br, Martin

Hi Martin,
I can finally confirm that the solution 2 of the link you gave me worked for me too!
I followed those indications before creating a vmdk with vmware converter, then I converted the vmdk in a raw image with "qemu-img convert" and finally doing a dd in the drbd device done the trick!

Still remains the fact that doing P2V with Win2k is some kind of wild horse (for example if you use the vmvga video driver it freezes), but you give me a big hand. So thank you very much!
