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) ?

Hi,
I just installed libvirt 0.5.0 on Debian Lenny with KVM 0.72 to try KVM migration support.
When I try to migrate a VM from one node to the other one, I have this error message:
libvir: error : this function is not supported by the hypervisor: virDomainMigrate
Is it really supposed to work ? Do I have to upgrade KVM to a newer version ?
Yes, it is supposed to work, but yes, you need a very, very new KVM. In particular, you need at least kvm-77, and it won't really work right until you get to kvm-79.
