Do they use -clock rtc? -clock dynticks should still work on RHEL 5
it's just that you won't get very accurate timer events.

You can only use -clock rtc with a single guest at a time so I doubt
people use it seriously. The other option would be -clock unix but I
can't see why you'd use -clock unix instead of -clock dynticks.

The only reason to keep -clock unix around is for non Linux unices.
