Please take a look at my previous reply.
It’s possible have VM’s in HA. Because when I does this test, I see
this issue.
“Highly Available VM failed. It will be restarted automatically.”
The issue is trying to manage the hardware using the power management interface.
If you need to power off or reboot a KVM host, use the Management button in the Engine
portal.
All HA configured VM will be restarted in another available KVM host.
