Hey Alexander,

I did those exact steps roughly two days ago...the host is still stuck in preparing for maintenance mode.  Confirming the host has been rebooted seems to have no effect.

Any other ideas?  Some way to hit the Ovirt Database and manipulate the value for what state the host is in?  Remove the host entirely from the back-end database?

IIRC when I had that issue (I removed the host physically before removing it from oVirt) I had to do the following:

- Right click in the grid on the host, and select confirm host has been rebooted (this is basically you telling oVirt the host has been fenced).
- After a while the host should end up as down (or unknown state).
- You should be able to select maintaince at that point, this might take a while (timeouts etc).
- This should put the host in maintaince and you should be able to remove it then.
