Am I correct in saying that setting HVM_PARAM_CALLBACK_IRQ to 0 disables interrupts in a HVM domain? I'm finding that an interrupt in a HVM domain is getting called well after I do the above. My theory is that there is something about the way HVM stuff works that an interrupt could be 'in the pipeline' and could still occur even though I set HVM_PARAM_CALLBACK_IRQ to 0 and mask off the interrupts (evtchn_upcall_mask = 1 for all CPU's) If that could happen, I'll need to work around it...
