I forgot to mention that if you want high performance you might also want to
isolate all except one CPU from Linux so that they can't be used for anything
except your virtual machines (see the CPU tuning > Isolating section in those
same notes).
Also you might want to disable any power saving modes in your CPU if you hate
trees and want lower latency (see the CPU tuning > frequency section in those
same notes).
There is also some notes on NUMA and PCI affinity.
Cheers,
James.
