bit of my system info here.

You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup01/LogVol00
# initrd /initrd-version.img
#boot=/dev/mapper/pdc_bfiahedhf
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-238.5.1.el5.028stab085.3)
root (hd0,0)
kernel /vmlinuz-2.6.18-238.5.1.el5.028stab085.3 ro root=/dev/VolGroup01/LogVol00 rhgb quiet
initrd /initrd-2.6.18-238.5.1.el5.028stab085.3.img
title CentOS (2.6.18-194.32.1.el5xen)
root (hd0,0)
kernel /xen.gz-2.6.18-194.32.1.el5
module /vmlinuz-2.6.18-194.32.1.el5xen ro root=/dev/VolGroup01/LogVol00 rhgb quiet
module /initrd-2.6.18-194.32.1.el5xen.img
title CentOS (2.6.18-194.el5xen)
root (hd0,0)
kernel /xen.gz-2.6.18-194.el5
module /vmlinuz-2.6.18-194.el5xen ro root=/dev/VolGroup01/LogVol00 rhgb quiet

Change default=1 to default=0 in grub.conf and reboot.

Kernels are counted starting with 0 so if your openvz kernel is the first listed, it should be 0.
