I have jboss AS 4.0 running on Ubuntu Dapper 6.06.1 LTS amd64 domU on 
Ubuntu Dapper 6.06.1 LTS amd64 dom0, hardware is Dell PowerEdge 1850 
dual Xeon 2 GB RAM, I think it's PERC 4e/Si RAID1.  I don't remember the 
exact Xeon, but it was pre-HVM.  There was nothing special at all about 
it except that jboss loves lots of RAM, so I had to give more to the 
domU, think it was about 768 MB - 1024 MB, didn't notice much difference 
in performance vs. running native with a regular kernel on the same OS / 
hardware.  OTOH I am only running a few simple applets, it's not a 
heavily loaded jboss.
