[libvirt] libvirt 0.5.0 and KVM migration

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 ? Thank you for your answers and congratulation for your precious work. -- _______________________________________________________________________ Mickaël Canévet.
