Hi Alexander:

I rebooted and now everything works. Very strange.

Cheers,

Joe

Hi Alexander:

No problem. Based on your suggestion, I just manually verified that
xen.gz was correct:

   1. rpm2cpio xen-3.4.3-3.el5.x86_64.rpm | cpio -idmv
   2. ls -l boot/xen.gz-3.4.3
      -rw-r--r-- 1 root root 548386 Sep 28 03:40 boot/xen.gz-3.4.3
   3. Verified that it matched /boot/xen.gz-3.4.3

Any other ideas would be greatly appreciated. I am stumped.

Regards,

Joe
