>>> Well that solves that. You have upgraded and upgraded... but not rebooted to switch kernels... or maybe you DID reboot but it still has the old kernel as the default.

>>> What I recommend you do is to remove any of the kernels you don't plan on using, and make sure your /etc/grub.conf is set to boot the kernel you want as default. I think the rpm package the OpenVZ project provides tries to update your grub.conf every time a new kernel is installed but it isn't always successful setting the new kernel to be default. SO... the lesson is, whenever you install a new kernel, make sure your /etc/grub.conf file is how you want it, then reboot if you want to switch kernels.
