Hi George,
With credit2 is it possible to assign the same scheduler with different
scheduling quantum (or configuration) to different cpu pool? For
example, 2 cpu pools all
use credit1 scheduler, but one's tick_time is 10ms (default timeslice
is 30ms) and the other one's tick_time is 5ms (default timeslice is
15ms). Thanks.
Regards,
Cong

There is no default quantum for credit2; it sounds like you're talking
about credit1.
It is possible, but not all the patches are in yet. There patches in
xen-unstable which create libxl calls that will change the scheduler
quantum of the scheduler of a cpupool. There are also patches
recently submitted which implement an xl command-line interface as
well, but they haven't been applied yet. Here is the information for
those, if you want to search for them:
Message-ID: <patchbomb.1330685517@kodo2>
Subject: [Xen-devel] [PATCH 0 of 2] [refresh] Implement xl interface
for setting credit 1 scheduler parameters
Hope that helps,
-George

Hi,
With credit2 is it possible to assign a same scheduler with different
scheduling quantum to different cpu pool? For example, 2 cpu pools all
