Hi,
I have a little question about scheduling the vservers. I have a server:
processor0 => Intel(R) Xeon(R) CPU 3040 @ 1.86GHz
processor1 => Intel(R) Xeon(R) CPU 3040 @ 1.86GHz
processorcount => 2
productname => ProLiant DL320 G5
and two vservers on it:
HOST:impec20:/usr/local/.aqadmin/home/aqadmin%(root)> more
/proc/virtual/40265/sched
FillRate: 6,0
Interval: 10,10
TokensMin: 15
TokensMax: 125
PrioBias: 0
cpu 0: 9830 44 0 0 0 RI 62 15 125 6/10 0/10 0 0
cpu 1: 6210 28 0 0 0 RI 62 15 125 6/10 0/10 0 0
HOST:impec20:/usr/local/.aqadmin/home/aqadmin%(root)> more
/proc/virtual/40266/sched
FillRate: 4,0
Interval: 10,10
TokensMin: 15
TokensMax: 125
PrioBias: 0
cpu 0: 3047 26 0 0 0 RI 62 15 125 4/10 0/10 0 0
cpu 1: 7750 25 0 0 0 RI 62 15 125 4/10 0/10 0 0
So basicaly i should have a 60/40 % for the servers, i disable idle cpu
by using a fillrate2 of 0.
So now i run a cpuburn program on each vserver:

4 root 34 19 0 0 0 S 0 0.0 0:00.04 ksoftirqd/0
Here i got a 50/50 distribution of the cpu. Is it normal ? Is it because
i have 2 cpu core and there is one more step to use for this case ?
i use:
