Hey,

Are any of you running RHEL5 OpenVZ(stable) kernel on CentOS 6 and how does that work? Any issues so far?

Thanks

    I know it's possible RHEL6 OVZ kernel on CentOS5, its been working solid for a few months now. Never tried the other way around though...

    Why would you do that when latest stable kernel from ovz is RHEL6 based??

  • apollo15apollo15 Member

    Because it's not 100% stable on high loads.

    Link? or your personal feeling?

  • apollo15apollo15 Member

    Google for it, nvm, please get on topic(first post).

    CentOS 6 OVZ kernel, not sure what OS on the host. Ask @prometeus

    No problems with CentOS 6 and openvz here.
    A internal server here:

    [root@vz03 ~]# uname -r
    2.6.32-042stab039.10
    [root@vz03 ~]# cat /etc/redhat-release
    CentOS Linux release 6.0 (Final)
    [root@vz03 ~]# uptime
    16:55:10 up 160 days, 3:29, 1 user, load average: 1.58, 1.92, 2.03
    [root@vz03 ~]#

    Using vswap ?

    The days of "2.6.32 isn't stable!" are over, btw. You'll be fine to use 2.6.32 on Centos 6 with no problems.

    We've been using CentOS 6 with OpenVZ (with vSwap) for quite a while now. Overall, it is very stable. 2.6.32-042stab061.2 has a few bug fixes that have made a really big difference on a few of our nodes.

    I'm sure using a CentOS 5 kernel with CentOS 6 will be more trouble than it is worth; just go with the CentOS 6 kernel.

    Yes
