'drift-compensation-for-windows-guests' - this is at least what the

as short as 'td'...).
It would work for any guest that uses rtc as its main clock source.
First step is qdev conversion for the RTC. You can then introduce a
drift property. I'd suggest something like drift=none|catchup|gradual.
The default can be none. We can also introduce a kvm machine type where
the default is catchup. Obviously, we don't support gradual today.
You can modify the default rtc settings using the -set operation (we can
give the rtc a default id). This lets localtime, td-hack, etc. all be
aliases for -set.
