Submitted bug to bugzilla.
I am now changing my scheduling and have noticed some different results,
perhaps you could help me in my studies....
I am running CPU intensive VMs and am trying to find out at what
scheduling they'll run the best (since the simulation being run over a
long duration, short periods and slices are not important). I have 8
VMs so my first few tests were running in periods of 1, 2, and 10
seconds, divided among the 8 domUs...
So I typed
Xm sedf (1,8) 1,2,10e9 125,250,1250e6 0 0 0
(ie, xm sedf 1 1000000000 125000000 0 0 0)
In this case, I excluded scheduling for dom0...
Could you please help me refine my scheduling.
Thanks,
David

sched=rrobin is not in unstable anymore.
The default is the SEDF scheduler, but you can still set sched=bvt
As I recall, there is some documentation on SEDF in tools/misc
We should file a bug that using a scheduler op on a non existent
scheduler does bad things.
