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

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

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?
