Thanks for the quick reply.

Is this process scheduling we're talking about here? Hmm, and I wonder how I
find out what scheduling algorithm my kernel is using.
So, this sounds feasible... except if virtual CPUs must have time shared equally
as the VMWare co-scheduling explanations imply. A scheduler for threads /
processes presumably wouldn't guarantee such a thing?
Maybe I'll go and investigate the KVM list....
Thanks
