---------------------------------------------
We probably don't want to assume kvm_intel.
In trying to reproduce it, I failed to add the host the first time with the
error:

Then I did nothing but try to add host again and it worked. So it seems that
something during the host add did the work, even though it ultimately failed.
Then I blew the zone away and rebuilt it without rebooting/rebuilding the host,
and it worked the first time. I still get this ssh command null pointer though,
which looks like it may have been introduced in March.
