Can I set CPU0 to > xenolinux0 and CPU1 to 3 others? 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 |
