Hello,

A stupid question -

Q1. Can I use a CentOS 6 x64 HW OpenVZ to run with CentOS 5 x64 guest?

Q2. Is it stable?

Q3. Is it supported?

Thank you very much for your kind attention.

Regards
George

I think it's a legitimate question... Anyway, yes to all three. We still run some CentOS 5 VMs on newer SL6/CentOS6 hardware nodes without any problems.

All of our CentOS 5 VMs have been freshly recreated, though. I'm pointing this out because there have been some reports about instability when using old VMs (ie. created on HN with Red hat 5 openvz kernels) that were transferred to newer HN (RH 6 kernels). YMMV... I'd search for such posts on the forum, mailing list archives and bugzilla to see what you might expect if you go this route.

I am happily running CentOS 5 VM's on CentOS 6 nodes and CentOS 6 VM's on CentOS 5 nodes.

The instability only seems to happen when you migrate from a 5 to 6 node an that was a few kernels ago so they may have worked that out now. One or two reboots seemed to correct it.
