1. what's the logic on deciding to move to next proxy ? is it per action 
(restart being comprised of stop and start. can the stop and start 
happen from different proxies)?

2. I'm guessing for 'engine' as proxy, vdsm will be installed with 
engine on same host.

is the plan to teat it as a separate instance of vdsm, listening on a 
separate port, or to assume an all-in-one deployment always?
if it is added as a host, just for fencing, it requires special 
treatment for that host. while if added as a separate instance (on a 
different tcp port), it doesn't have to be defined as a host in the system.

iirc, we can install vdsm, and launch multiple instances of it (at least 
we could in the past).

3. i didn't understand the fqdn/ip proxy mode, if it is not an existing 
host in the system, how will engine communicate with it over secure 
xml/rpc? (i can understand selecting a specific host, but not a text box 
for fqdn/ip).

thanks,
