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.

Time OUT!

I don't know when you rebooted last and when you last updated but it
looks like the default boot (0) is a non-ovz kernel.  If you look at
entry #2 (third entry), isn't that the PAE ovzkernel you are looking
for?  Change default to 2 instead of 0 and then reboot.
