Problem booting Microsoft Windows KVM virtual machine

Problem booting Microsoft Windows KVM virtual machine

[RaSca]

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
<domain type='kvm'>
   <name>vm-sophos</name>
   <uuid>213a464c-73ad-8122-3647-7ff6b78d9e07</uuid>

       <source bridge='br0'/>
       <address type='pci' domain='0x0000' bus='0x00' slot='0x03'

       <model type='cirrus' vram='9216' heads='1'/>
       <address type='pci' domain='0x0000' bus='0x00' slot='0x02'

     <memballoon model='virtio'>
       <address type='pci' domain='0x0000' bus='0x00' slot='0x04' 
function='0x0'/>
     </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

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!
