[libvirt-users] virsh snapshot delete / live-migration issues

Hi, I'd like to live-migration after snapshots deleted. But it doesn't work.Here's my steps: # virsh snapshot-create VM # virsh snapshot-delete VM Snapshot # virsh migrate --live VM qemu+ssh://localadmin@compute3/system And It comes out this message: # internal error: unable to execute QEMU command 'migrate-set-capabilities': There's a migration process in progress Even I create a no-metadata snapshot, it still have same error. After I reboot the VM, the live-migration finally works. Does it has any suggestion way or command to solve this problem without reboot the VM? Here's my environment: Ubuntu 14.04.5 LTS Compiled against library: libvirt 1.3.1 Using library: libvirt 1.3.1 Using API: QEMU 1.3.1 Running hypervisor: QEMU 2.5.0 Best regards, Chihhang Wu
