There's probably more info in "/var/log/xen/xend.log", but I suspect the
whole problem is that you're trying to boot a Linux (para-virtual)
domain from "cdrom", which isn't supported at all (because the
Linux-builder doesn't run a BIOS, which is how the CDROM-boot normally
works - instead, it just loads the kernel and initrd into memory and
sets the VCPU registers to some values that makes it possible to run the
Linux kernel from there). 

I'm not sure, but I don't think ":cdrom" is a valid addition on a PV
domain. 

[It will probably work if you use a "hvmbuilder" form, e.g
kernel="hvmloader" and builder="hvm" instead of the kernel/linux
settings that you use now. And you'd have to give "whole disks" to HVM,
as it doesn't support partitions. [And it won't make a PV domain, of
course - it may be possible to convert it after install, but possibly a
messy business].
