A couple of months ago I tried to implement this for kvm.
I failed on rpc though.
If you got as far as writing some code for the QMEU driver do post it to
the list even if its not finished/usable. The RPC stuff can be a little
tricky to understand for those unfamiliar with it - but it is easy enough
for one of us to add.
It should be as "easy" as setting setpriority(2).
That's just one tunable - there are others like sched_setparam, and
sched_setschedular
