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.
