[ovirt-users] Hung task finalizing live migration

[Maton, Brett]

Thanks for the pointer Mikhail, however I don't get any tasks listed with
that command:

vdsClient -s 0 getAllTasksStatuses

/usr/share/vdsm/vdsClient.py:33: DeprecationWarning: vdscli uses xmlrpc.
since ovirt 3.6 xmlrpc is deprecated, please use vdsm.jsonrpcvdscli
  from vdsm import utils, vdscli, constants

{'status': {'message': 'OK', 'code': 0}, 'allTasksStatus': {}}
