Hello, I'm having some trouble allocating resources using openvz. It simply ignores memory limits, and does not allocate the CPU correctly.

Below are some details:

[root@skywalker ~]# vzcpucheck
Current CPU utilization: 10064
Power of the node: 1276960

for memory settings please read this article:
http://wiki.openvz.org/Vswap

on rhel6 based kernel you set memory limit with physpages parameter

take a look to ve-vswap-*.conf-sample config files

about cpu
You have set some with cpulimit and maybe other cpu related parameters
if you want set it to unlimited set --cpulimit 0

if you have more questions please paste CT config file

Paparaciz, thank you for your reply.
When I set CPU Units to be 0, I received this error:

I said cpulimit, not cpuunits

in your config you are setting limit 90

please take a note, that to calculate cpulimit you have to sum all cores which you give for CT
so if you have 8 cores cpu all power is 800%
8cores*100% = 800
if you want that CT don't use more than 50% of cpu you have to set it to 400
with limit 90 you set ~10% of cpu power.

if you set for CT 2 cores (--cpus X)
than to calculate limits you need to sum: 2cores*100%=200%
with limit 90 it would be little bit less than 50%

Oh, thank you so much! It worked Smile

Sorry to have confused cpuunits with cpulimit.

Could explain to me how I should configure the memory limit with 6 RHEL kernel?

Thanks again,
I set using the commands:
vzctl set VMID --swappages: XXXXM --save
vzctl set VMID ---physpages: XXXXM --save

Problem solved =)
