As we don't want to assume that this test xen will even boot, the safest thing is to edit your /boot/grub/menu.lst (or use yast [System -> Boot Loader]) to copy your current xen boot entry.  Leave everything identical between the two entries except for the hypervisor (change /boot/xen.gz to /boot/xen-test.gz) and the title line to indicate the test entry (add something like "- test" to the end of the title line).  If you use yast, the title entry is in the label column.

Copy your newly created xen.gz to /boot/xen-test.gz (be careful not to copy your new file on top of any existing /boot/xen.gz).

Reboot the node and manually select the test selection.  If the boot succeeds, try your experiment.  If the boot fails, just reboot normally and verify your changes to the menu.lst.
