Description of problem:
When pressing the Power Off button on a Libvirt VM in Foreman, I get a message that the VM is now Running and the button shown in the VM dialog is still the Power Off one.

How reproducible:
always on Libvirt compute resource

Steps to Reproduce:
1. go to Infrastructure -> Compute resources -> <Libvirt resource> -> Virtual Machines
2. Power Off one of the VMs found

Actual results:
The VM is actually and really powered off but Foreman declares success for the VM now Running and still shows the "Power Off" button in the VM dialog then appearing.
If I then click again on the "Power Off" button, it executes actually a "Power On".

Expected results:
Foreman congratulates me to the VM now stopped and shows the "Power On" button.

Additional info:
The UI dows not reflect the actual state of the VM. It takes a little while for the VM to power down, but the refresh after submit is 'too quick' and does not pick up the changes. When I refreshed the page after the VM powered, everything was as expected.
