Xen users - Jun 2006 - Problems w/ spoofing VM clock, independent_clock

I''m trying to accelerate the system clock on a VM guest. I''m
setting the
independent_clock flag to 1, then using the "date" command to change
the
system clock. However, whenever I do this, the VM guest becomes
unresponsive. When I syncronize the VM clock to the host clock, everything
goes back to normal.

Two questions:

1) Why is the VM guest freezing when the host time does not agree with the
guest time?
2) How does the guest determine its own (independent) software and hardware
clock?
2) Is there an alternative to running "date" command to change /
accelerate
the system clock?

I''m using the Xen 3.0 Demo CD on a P4 2.7GHz, 2GB RAM.

Thanks,

Kevin Cheng
