Upstream phoenix lab has stabilized, but after the outages we are finding some issues probably caused by it. One of them is that th vm migration is not working, ew have two hosts srv05 and srv06, and we want to migrate vms from 06 to 05 but we find those errors on vdsm on 05: Feb 04 02:56:50 ovirt-srv05 vdsm[5170]: vdsm vm.Vm WARNING vmId=`43415276-a7bf-4c86-b0e9-70a5f6d39a40`::Unknown type found, device: '{'device': 'unix', 'alias': 'channel0', 'type': 'channel', 'address': {'bus': '0', 'controller': '0', 'type': 'virtio-serial', 'port': '1'}}' found Feb 04 02:56:50 ovirt-srv05 vdsm[5170]: vdsm vm.Vm WARNING vmId=`43415276-a7bf-4c86-b0e9-70a5f6d39a40`::Unknown type found, device: '{'device': 'unix', 'alias': 'channel1', 'type': 'channel', 'address': {'bus': '0', 'controller': '0', 'type': 'virtio-serial', 'port': '2'}}' found Feb 04 02:56:50 ovirt-srv05 vdsm[5170]: vdsm vm.Vm WARNING vmId=`43415276-a7bf-4c86-b0e9-70a5f6d39a40`::Unknown type found, device: '{'device': 'spicevmc', 'alias': 'channel2', 'type': 'channel', 'address': {'bus': '0', 'controller': '0', 'type': 'virtio-serial', 'port': '3'}}' found Feb 04 02:56:50 ovirt-srv05 vdsm[5170]: vdsm vm.Vm ERROR vmId=`43415276-a7bf-4c86-b0e9-70a5f6d39a40`::Alias not found for device type graphics during migration at destination host

After that sanlock complains: Feb 04 02:56:50 ovirt-srv05 sanlock[1055]: 2015-02-04 02:56:50-0700 1453 [1055]: cmd 9 target pid 6479 not found
