So I'm getting further, but now the bootstrap.log has more errors below.
If I follow the test day instructions, it indicates to install vdsm and
includes instructions, but it's clear that ovirt-engine is configured by
default to push out vdsm and install it.  If I've already configured and
installed vdsm on the node is there any way to not attempting to bootstrap vdsm
at all and just attempt to have it connect?
