Looks like the VE is running out of memory. Give it more!

Hi jarg,

Thanks for your advice.

This box is for testing purpose running Athlon 64 with 1G RAM on box. There are 4 VEs created but NOT all running simultaneously.

Memory
======

root@vz2:/# free -m

             total       used       free     shared    buffers     cached
Mem:           256        245         10          0          0          0

The running VE, in problem, is identified as 102. Please advise how to increase the memory on this VE? Whether run;

vzctl set 102 --vmguarpages 371M:372M --save

vzctl set [vpsid] --vmguarpages 371M:372M --save

And how to increase the memory on all VEs simultaneously? TIA

vmguarpages is not actually the problem. It is privvmpages and probably others. I would recommend to set all parameters as in http://wiki.openvz.org/UBC_configuration_examples_table "C".

When you have one working config, copy it, edit it with a text editor, delete the VE unique stuff (hostname, VE ID, IP address, ...) and use
vzctl set XYZ --applyconfig XYZ (or something like that, please see the man page)
to apply the config to other VEs.

On host:-

I found the sample file. Copied and renamed it as ve-vps.revise.conf

Changed it as follow;

$ cat /etc/vz/conf/ve-vps.revise.conf

But some of the items I can't find on the table. I'll remove "#...." later. They are for easy reference.

Quote:

and use
vzctl set XYZ --applyconfig XYZ (or something like that, please see the man page)
to apply the config to other VEs.

However I have no idea how to use the file. The guest 102 (VE) is running. Please advise. TIA

Furthermore on creating VE running;

$ sudo vzctl create 102 --ostemplate ubuntu-8.04-i386-minimal --config vps.basic

Where is vps.basic ?
