CDROM's are only used in fully-virt guests - your config here is a paravirt
guest so there's no boot option available. Paravirt guests can only boot
off a kernel/initrd (or via a bootloader like pygrub). Fullyvirt guests
have a real BIOS so boot from the MBR of the disk, from CDROM, Floppy
or PXE from the network.
