I did.  I basically followed "Up and Running with oVirt 3.5", except I 
used 3.6 packages.

Well, I pre-created the 'ovirtmgmt' bridge, as I had to do that under 
3.5 otherwise I ran into problems during setup.  I can't recall offhand 
what the bug was (I posted about it a while back), but perhaps whatever 
it was has been fixed in 3.6, and I shouldn't pre-create the 'ovirtmgmt' 
bridge?

After I sent my earlier e-mail on this issue, I played around with a 
couple things and actually got it up and working (the interfaces turned 
green, etc.).  As a test, I rebooted the host, but now I can't even ping 
the host.  it is at the office, so I won't have physical access to it 
until I go in in a few hours.

CentOS 7 minimal (after 'yum update', I think it it 7.2?).  oVirt is 
3.6.1, I believe (whatever version is installed form latest repo packages)

Since I have lost access, I suspect something happened to the 
'ovirtmgmt' interface.  There is nothing on it that matters, so I may 
just do a fresh install, but without pre-creating the 'ovirtmgmt' bridge 
and see if the setup does it (which I understand itis supposed to?)
