[libvirt] LIBVIRT migration



Hello:
I did more tests, but I don't find the problem.
this is a debug I've got setting LIBVIRT_DEBUG=1, I'd appreciate any help.
Regards.
Marcela.

Hello
I'm having problem using migration. I'm working on ubuntu 10.4 and this versions of libvirt and virsh:
virsh # version
Compiled against library: libvir 0.7.5
Using library: libvir 0.7.5
Using API: QEMU 0.7.5
Running hypervisor: QEMU 0.12.3

This is the error.
virsh # migrate scompi1 qemu+ssh://rionegro/system
error: Unknown failure

This is the log on the destination, that show that there is no communication problem, but it has a problem starting the guest on destination.
