Verif y wh ich kern el is in u se
The kernel-xen package may be installed. Use the uname command to determine which kernel
is running:
$ uname -r
2.6.18-159.el5xen
The present kernel, "2.6.18-159.el5xen", is running on the system. If the default kernel,
"2.6.18-159.el5", is running you can skip the substep.

The grub.conf file determines which kernel is booted. To change the default kernel
edit the /boot/grub/grub.conf file as shown below.
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz

Notice the d ef au lt = 1 parameter. This is instructing the GRUB boot loader to boot the
second entry, the Xen kernel. Change the default to 0 (or the number for the default
kernel):
default=0
