[libvirt] virsh save command will throw an error when used with qemu

[oliver]

Hey subscribers,

I have a problem with the actual libvirt/virsh release and qemu-kvm 
0.13. if i want to save the actual status of my virtual machine i get 
the following error:

lserver ~ # virsh save windows /virtual/windows_ram
error: Failed to save domain windows to /virtual/windows_ram
error: internal error unable to execute QEMU command 'migrate': An 
undefined error has ocurred

First i asked in OFTC but there was said, that this could be an error 
with the qemu console command.
The system details:

lserver ~ # uname -a
Linux lserver 2.6.36.2 #2 SMP PREEMPT Wed Dec 29 02:58:41 Local time

It was for me not possible to get further debug info from libvirt.
