Hi Peter,
	I have been stress testing the box without any hypervisor software
loaded and all seems pretty stable.  I left parallel buildworlds running
along with a few background jobs of dd if=/dev/urandom count=10000 |
sha256 randomly running in the background for 24hrs. I am now running
the buildworlds along with maxing out the network card with
bidirectional traffic. Its been up for 6days without issue.

Any other thoughts / tests I can do to try and help narrow down this
issue ?

	---Mike
