New OpenVZ Stable Kernel Released

| |

The OpenVZ development team sent out a email today announcing the availability of kernel-2.6.9-023stab037.3. The main difference was stated as:

In-kernel sysfs/uevent layer is now updated to be compatible with FC5 and SLES10 userland.

What that means, I believe, is that whenever one tried to create a VPS of a distro that expects a newer kernel than 2.6.9, that distro would get very cranky... so installing FC5 and SLES10 VPSes used to require using the OpenVZ testing kernel based on 2.6.18. With this kernel upgrade, that no longer seems to be the case. Since I don't have any FC5 nor SLES10 VPSes, I haven't tested this out. Hmm, I wonder if FC6 as a VPS is supported yet?

After looking at a lot of the changes on the changelog page, there seems to be a lot of fixes. I've updated my OpenVZ Host machines and rebooted and it seems to be running nicely... but one always has to watch /var/log/messages on the Host OS as well as /proc/user_beancounter on the VPSes.

I think I have all of my VPSes tuned up well enough because I haven't noticed any failcnt increments in some time.
