In a timer patch in RHEL5u1 (by Alan Cox), is the comment:

"Xen itself has issues with multiple differing guest GZ rates"
(and I assume that GZ is a typo, should be HZ)

Can anyone explain this further or are there experimental
results to back it up?  We are seeing some strangeness with
running multiple pvm guests with different HZ rates and wonder
if this is related.

Thanks,
Dan


===================================
If Xen could save time in a bottle / then clocks wouldn't virtually skew /
It would save every tick / for VMs that aren't quick /
and Xen then would send them anew
(with apologies to the late great Jim Croce)
