This is a list of dom0+domU combinations with plain
26502:d1bf3b21f783:

pvops dom0 + pvops domU
  - very first domU hangs in hpet_rtc_interrupt
 
  - xl migrate domU localhost
    migration works, but new domU hangs in hpet_rtc_interrupt


sles11 dom0 + sles11 domU
  - guest prints "hpet1: lost 2201 rtc interrupts"

  - xm migrate works



I will retest more combinations with the source state above.


Now I tried x86-HVM-RTC.patch, and the result is that the very first
pvops guest boots fine, and also two xl migrate to localhost work fine!
I will do some more testing to see if its consistent.
