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 ?
