We are using a Dual Opteron with 8 cores and 32 GB RAM running Ubuntu with this Kernel :

2.6.24-openvz #2 SMP Fri Oct 31 23:39:58 CET 2008 x86_64 GNU/Linux


We need to increase the power of our VE 106 !



vzcpucheck
Current CPU utilization: 255000
Power of the node: 880229



vzcpucheck give us the Power of the node: 880229

VE0CPUUNITS=5000 /etc/vz.conf

with vzsplit we have divided the unit into 3 VE and with

vzctl set 106 --cpuunits 220037 --save

we have reached the maximum value of cpuunits


increasing cpuunits gives us an error :

vzctl set 106 --cpuunits 293383 --save
Setting CPU units: 293383
Saved parameters for VE 106
root@vic:/etc/vz/conf# vzcpucheck
ERROR: VE0 CPU units not set, or set too high!
Probably you have not started /etc/init.d/vz



This is our configuration for VE 106

What can we do to give this VE more Power ?

Which asterisk optimizations can be done ?

Some more information om this problem...

- VE0 shows barely any load / CPU utilization usually < 10%
- Guest VEs show frequently 100% usage on all 8 CPU cores.
- processes seem to be stalled and system/kernel time is very/unusually high on the guest VEs

System should have plenty of power available but obviously it does not get to the guests...
