Awesome, this is exactly what I was looking for! Thank you!
One last thing - Is there a data dictionary available somewhere for the Ovirt Postgresql DB tables and views? Some way I can view the full schema and understand what data is located where? Documentation online seems very scarce in this regard.
Thanks again, I truly appreciate the help!

That should have worked, but if all else fails you can always set the host in maintaince in the database doing this in the engine database:
update vds_dynamic set status=2 where vds_id = <id_of_host>
you can figure out the id of the host by doing this
select vds_id from vds_static where vds_name='<name_of_host>'
If you are feeling brave you can combine the two into a single statement, but I would be sure you have the right host before you do that.
Then once you have updated the status, you can refresh the webadmin and the host should be in maintenaince mode and you should be able to remove it normally. I would not attempt more manual manipulation of the database than setting the status to 2 (which is maintenaince).
