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:

No matter how I change the CPU Units, the VM is always with those settings, 179MHz per core ..
Now, inside 101.conf
VMGUARPAGES="792576"
PRIVVMPAGES="792576"
Would be 3096m of ram, but when I run the command "free-m":
[root@skywalker conf]# vzctl enter 101
entered into CT 101
root@aurora [/]# free -m
total used free shared buffers cached
Mem: 8388607 406 8388201 0 0 67
-/+ buffers/cache: 339 8388268
Swap: 0 0 0
root@aurora [/]#
Memory limit is not imposed, I'm at an amazing machine, but I can't get any result with the VMs..
Using CentOS 6 on Host..
For this reason I was almost moving to xen, but I have complete vms hosting more than 100 sites, and I think a conversion would not be possible ..
Could anyone help me please?
I do not know what else to do ..
Can I perform a reinstallation of openvz?

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%
