We were unable to find any info googling. It appears you cannot boot a Paravirtualized DomU directly to CD-ROM? So we temporarily changed our Paravirtual Xen DomU to boot from HVM or Full Virtual Machine. Our environment has Xen running on HVM capable hardware (we can run Full Virtualization) with LVM Block devices for disks. Our Paravirtual DomU is called guest-1 First backup your Running Xen config. Save it to /etc/xen/vm/guest-1.run xm list -l guest-1 >/etc/xen/vm/guest-1.run You will use this file later on. Novell’s documentation on how to save Running Xen DomU config. http://www.novell.com/documentation/vmserver/pdfdoc/config_options/config_options.pdf Look for “Virtual Machine Settings”. I found it easier to modify the startup config in /etc/xen/vm/guest-1 than modify the file that is outputted from the Novell Running config backup. Backup the original Startup config (I believe this file gets created when you first build a new VM in virt-manager.)
