We are currently testing with your patch. Your patch gives dom0 greater
than 75% of the CPU. This is fine if dom0 is allowed to run only I/O
intensive workloads. Is this an implicit assumption here.
Our view has always been that dom0 is primarily a service domain. If
that isn't the case then you may want to reduce its guarantee (easily
done) but bear in mind that this can have a bad effect on domU I/O
performance. Hopefully my patch gives a balance that strongly favours
dom0 but not so much that other domains get starved for significant
periods.
