[ovirt-users] hosted engine vm.conf missing

Tue Dec 1 10:13:44 EST 2015

There was an error message on the setup, but everything continued on and
the hosted engine was available so I didn't think much of it.

If there is some way of recovering this setup I would like to give that a
try, if you can provide some instructions that would be great, thanks.
