How can I resolve the drifting clock for my Virtual Machine?

My Virtual Machine's clock drifts pretty significantly. There's documentation out there about dealing with this, but nothing seems to be working very well.

Anyone have any suggestions, things that worked well for them, ...

Supposedly updating regularly via ntp is not a good solution.

vmware have a really good PDF doc on this problem.

Basically, the host will slew the ticks delivered to your guests as it can. Don't run NTP or timed or junk like that. Just install vmware-guestd and let the host slew your ticks. If you still lose ticks, then any other solution will have major drift too.

If you can, use a guest OS that has a low frequency tick rate. Newer versions of Linux come with 1000Hz ticks, but it used only to be 100Hz. That seems easier for the host to deliver. A kernel rebuild is usually needed to change the HZ value.

That's the solution I would recommend, though. Why is it not considered good at your location?
