Currently, domains get statically assigned in a round-robin
fashion to CPUs. It makes sense to add a dom0_op to enable a
domain to be pinned to a specified CPU -- I'll knock up a patch
for this.
In the future, we intend to load balance (non pinned) domains
between CPUs, but this isn't very high on our todo list.
[BTW: If you can't wait for my patch, then you can 'hack' it by
creating tiny domains 2 and 4 that you never start. You'll end up
with 0 on CPU 0 and 1,3,5 on CPU 1. ]
Best,
Ian
