You often see this error after doing a ''yum update'' or equivalent. Check that the reference to the xen bits in your grub config is pointing to the correct version and number you expect. HTH, Matt.

Did you install the gitco Xen packages? - I see this problem all the time if I *forget* to fix my grub.conf after an update. By the looks of it, you might have a mismatch between your kernel and module lines. This is what one of my boxes which uses the Gitco repos looks like (and looks very similar to your second entry): title CentOS (2.6.18-164.11.1.el5xen) root (hd0,0) kernel /xen.gz-3.4.1 dom0_mem=512M noreboot module /vmlinuz-2.6.18-164.11.1.el5xen ro root=/dev/VolGroup00/LogVol00 netloop.nloopbacks=128 module /initrd-2.6.18-164.11.1.el5xen.img Make sure your kernel, vmlinuz and initrd lines all point to the same versions of those three files.

I''m not quite sure Xen 3.4.2 will work with the stock CentOS Xen Dom0 Kernel.
