Yeah, I'll submit it this afternoon once I head into the office.  Once I 
saw 2.6.16, I realized we're out of time :-)  I hope we can fix the 
xm-test regressions though before 3.0.2...

Yeah, I just allocated a faultcode for VmError and XendError and handled 
those specifically.  In general, we could probably an exception to
