You should be able to boot another domain from the CD, using the
initrd to create a ramdisk as the root file system (populated
from root.tar.gz), with the CDROM mounted as a read-only /usr.

> [8];Unable to find CD-ROM and NFSDIR not specified

The above message suggests that it was unable to mount the CDROM
for /usr. This is pretty odd, as if your domain0 image managed to
find the CD, its very strange that domain1 couldn't find it.

>From domain0, please can you send me the output of "df", "mount"
"ls -l /dev/cdrom_link".

Presumably you're using the default /etc/xenctl.xml and
/etc/xen-mynewdom script, and invoking xenctl with the following
vommand line?

 xenctl script -f/etc/xen-mynewdom
