The sched_credit.c part of this patch looks good to me (except for
the coding style issues). Before adding per-domain tunable time
slices though, shouldn't we make the global time slice tunable?

Hi,

This patch intends to add tunablity for time slice on credit scheduler.
Each domain can change time slice.

for example,
xm sched-credit -d 0 -s 20
(unit is msec)

c.f.
1)libxc(pyxc) forgets help message for cap.
I add it on tools/python/xen/lowlevel/xc/xc.c

2)time slice can set from 1 to 100(msec).
I have see VNC connection timeout problem for many domain on one CPU.
For this reason, it can set time slice from 1 to 100 msec.
Of course, default value is 30msec.


Thanks
