Re: [Xen-users] how to boot a para-virtulized vm from cdrom after installation

[Mark Pryor <tlviewer@xxxxxxxxx>]

Jun,

before you try again, mount the ISO and copy locally the vmlinuz-xen/initrd-xen 
from the DVD.

Those two files will be referenced from your config or the xm/xl cmdline.

In your disk=[] line, put the DVD first (sometimes it matters).

Now,
xm create kernel=/home/me/vmlinuz-xen ramdisk=/home/me/initrd-xen xen_vm_config

the boot files should now see the DVD and source it.
