[libvirt] libvirt 0.5.0 and KVM migration

[Mickaël Canévet]

Thanks for your quick answer.

I forgot to restart libvirt on one node.

Now I have an other error message:

libvir: QEMU error : operation failed: failed to start listening VM

Is there any kernel limitation also ? will it work with my distro 2.6.26
kernel with kvm-79 userspace component or do I have to have kvm-79
kernel module also, or even kernel then 2.6.26 ?

In other (debian) words, will an "apt-get update kvm -t
experimental" (which provides kvm-79) be enough on my lenny (I would
like to limit unstable or experimental packages) ?

Thanks
