virsh live migration

[Marcus Paiva]

Hi,
i do not manage to do a virsh migrate live command.
Using Ubuntu Server 10.04 x64

root@svr50abl:~# virsh list
 Id Nome Estado
----------------------------------
 18 Winxp executando
 19 teste executando

root@svr50abl:~# sudo virsh migrate --live 19 qemu+ssh://10.1.5.1/system
root@10.1.5.1's password:
erro: unable to set user and group to '116:127' on '/var/lib/libvirt/images/teste.img': No such file or directory

teste.img has root:root (xrw)

10.1.5.1 is a functional kvm host too

The image file should be shared (for example over NFS) and visible on
both hosts. It looks like you are migrating to a host that does not
have /var/lib/libvirt/images/teste.img.

Please check with libvirt, this is not a QEMU bug.

You can try to copy the image file from source to destination before migration.

Closing, as this is a libvirt issue, not a QEMU bug.
