Hi all,

I have created a virtual machine with open vz. My problem is, when I'm setting cpulimit to the machine. Doesn't show errors, but not setting the parameter.

I read the manual open vz:

--cpulimit num[%]Limit of CPU usage for the VE, in per cent. Note if the computer has 2 CPUs, it has total of 200% CPU time. Default CPU limit is 0 (no CPU limit). --cpus num sets number of CPUs available in the VE.I have proved these examples:

vzctl set VMID --cpulimit 25 --save

and

vzctl set VMID --cpulimit 25% --save


What is the problem?? Thanks for you help

pls post the output of 'pveversion -v'
 
Hi, version of proxmox is 1.5.

The command set the cpulimit is executed correctly and returns "Setting CPU LIMIT: XX".

Which I see the cpu limit in the virtual machine?

Thanks for your response

Sorry.

running kernel: 2.6.24-10-pve
proxmox-ve-2.6.24: 1.5-21
pve-kernel-2.6.24-10-pve: 2.6.24-21
qemu-server: 1.1-11

vncterm: 0.9-2
vzctl: 3.0.23-1pve5
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1dso1
pve-qemu-kvm: 0.11.1-1
 
The vzctl-command return code 0 which means success. So why it returns 0 ? Because the changes can be written to the config but not be "interpreted" by some kernel versions.

So why is the field shown in version 2.6.24 ? The developers should answer this question. For me it isn't really bad but if someone doesn't know the background the person will be irritated.

EDIT: dietmar was a little bit faster ;)
 
Hi,

I'm using server compatible with set cpulimit...

How can I see if the changes are done? Exists some command with linux that's show the cpu limit?

Thanks!!
