Any details about the problems?  HPET is important to some guests.

Seems like HPET reaction is too slow to satisfy some guests(for it would
replace PIT).

Here is the thread last time.

Thanks. We can address this in three ways: first, adjust the guest not to do timing related tests when virtualized (since no matter what we do, the tests may fail). Second, I think we should implement userspace ack notifiers (similar to tpr access notifiers already present). Third, we can implement a kernel hpet, which, after we solve the zillion bug it introduces, will also give a nice performance improvement for hpet intensive workloads.
