RedHat SWAP memory
Admins,


How can I configure the server so that it will utilize the swap file as little as possible? Please correct me if I'm wrong, I would say change the value of sysctl - vm.swappiness? And if, how can I keep it permenatly even after rebooting the system? since no related parameters in /etc/sysctl.conf?

You can add a line to /etc/sysctl.conf, for example
Code:
vm.swappiness=0

I wouldn't go zero. That would disable swapping entirely:

My box living with another VMs in the same host, so I don't want my box swap the others!

Swapping won't happen if you have more than enough ram. If swapping becomes necessary, and you have no swap, your system will stall terribly. If all else fails, you might consider a separate/private swap partition for your own VM?
