Installing openVZ in a production server [message #47148]

Hello,

I have a dedicated server running centOS with cPanel (Web hosting management control panel) installed.
Also, I have another VPS server which has a special website in it. in order to decrease the hosting costs I was thinking of creating a VPS container in the dedicated server and cancelling the VPS server.
My question is: Is it OK to install openvz software in the active dedicated server (which has cPanel with some sites) ? and then creating a VPS account? will this cause compatibility issues with the cPanel?

Thanks

It's only kernel (few extra syscalls + changes in memory managament (vSwap), filesystem (quota support for ext{3,4}, reiserfs (AFAIK) & nfs), etc) and one tool (vzctl).
Your cPanel should work without any problems with OpenVZ kernel.

First of all try to reboot with new kernel and if everything will work them install vzctl.

Remember: /vz need some extra disk space so if you don't have enought free space on a root partition (/) then mount any other free volume (for example LVM, or extra disk) at /vz.

And what if it didn't work? Can I uninstall openvz kernel and back to the original CentOS kernel?
