Description of problem:
I started a HA VM (migratable but with preferred host) through run once and set the preferred host as the one VM should run on. After that when the host gets fenced or goes down with whatever reason, the HA VM is not restarted on another host.

Version-Release number of selected component (if applicable):
4.1.1-1

How reproducible:
always

Steps to Reproduce:
1. edit a VM, set it as highly available and set preferred host and auto migration when necessary policy
2. run the VM with run once and set preferred host as the one VM should run on
3. fence the preferred host

Actual results:
HA VM is not restarted

Expected results:
HA VM should be started on another host
