Thanks for your advice. So what do you think, is it really a good idea
to start with
so many VCPUs before we see what kind of performance we get from only one?

They use Vmotion extensively in the VMware cluster so I don't think
the VMware admins have a lot of concern where the individual VM's are
running. I will diskuss this issue with them.
