Hi, Tristan,
Good news anyway, however I'd like to suggest adding either domU or
domVTI running together with dom0, while on different physical processors. Most
host SMP bugs we sent out recently are only seen with multiple domains on
different processor. Idle domain is special which may shade some potential SMP
issues there. ;-)
Thanks,
Kevin
