Hi,

Is there a way by which I could find out what %age or weight of CPU a
particular domain is being alloted with?

For instance,
I have 3 domains up

# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      128     1 r-----   713.9
vtux01                             1       64     1 -b----   564.4
vtux02                             2       64     1 -b----   557.9
vtux03                             3       64     1 -b----   553.1

How do I find out what %age of CPU is being given to each of the domains?

Also,if I want to give these domains a CPU share like this dom0 :
vtux01: vtux02: vtux03 = 1:3:3:3, how do I accomplish this?

I have executed the following commands, but I am not sure if any
modification is required.

#xm sched-bvt 0 10 0 0 0 0
#xm sched-bvt 1 30 0 0 0 0
#xm sched-bvt 2 30 0 0 0 0
#xm sched-bvt 3 30 0 0 0 0

Please explain.
