Symptoms

After updating a working PVM guest, the next reboot will hang.  The boot messages display:

No Kdump initial ramdisk found
rebuilding /boot/initrd/.xxx

Since RHEL 6.3 there is limited support for kdump on full-virt Xen DomU
This kdump marker may now be removed on supported configurations
