[ovirt-devel] Help with issues with migration

[David Caro]

Hi!

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

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

but it seems that the vm is starting up:
  Feb 04 02:56:50 ovirt-srv05 systemd[1]: Starting Virtual Machine qemu-el6-vm03-phx-ovirt-org.

  -- The start-up result is done.


But it shuts down:
