Hi,
for kvm yes - you have one kvm-process for each vm.
look with "ps -aux | grep VMID" and "top".

Hi,
e.g. with

top -b -n 1 -p 20725

there a certainly other options...

You can also do something like this:

top -b -n1 -p `cat /var/run/qemu-server/111.pid`

Thanks,
But these numbers are in difference with what Proxmox shows in the web interface, and the memory is in percentage of whole server's memory,
Can't we get more accurate numbers?

There will be an API in V2.0, where you can get all those values - for now, you need use values form ps/top.

Are we allowed to use Proxmox source and get these information as Proxmox get them?

Thanks, Would you please help me a little bit, in which package I must look into the source? ftp://download.proxmox.com/sources/
There was nothing useful in pve-manager_2010-02-04.tar.gz

There was nothing useful in pve-manager_2010-02-04.tar.gz

in pve-manager, take a look at bin/test/testrpc.pl

that way you can call all methods from lib/PVE/ConfigServer.pm (i.e. 'vzlist')
