Also is any scheduler going to include any algorthm to handle
gang scheduling of multiplie vcpus?
It remains to be seen whether gang scheduling is actually necessary. I'd
like to see how well some combination of "bad pre-emption"
avoidance/mitigation coupled with biasing the scheduler to run vcpu's of
domains that already have vcpu's running.
Strict gang scheduling is likely to lead to a lot of wasted cycles, and
I expect we can do better. The first step is to define a set of
workloads we want to optimise for, and collect some traces.
