I think this is really a simple matter of which type of cdrom is being emulated by kvm.  In my experience, there are at least two behaviors of CDroms that have their tray ejected on boot.
a.) pull in the tray (eject -t) which would have a cd in it, and then would be available for the bios boot selector.  This is typical behavior of desktop machines.
b.) do not pull in the tray , leave out, and thus theres no CD available to boot. My thinkpad has this type of CD, the cdrom is not capable of "eject -t".  Ie:
 | $ eject -t /dev/cdrom
 | eject: CD-ROM tray close command failed: Input/output error

KVM implements 'b'. It appears that the bug opener expects 'a'.
