xenguest-install from python-xeninst-0.94.0-1 creates an entry like this when using iso images (hardware based virtualization): cdrom="/path/to/your/file.iso" This no longer (with the xen version currently available in fedora pre) works, the syntax is now like this: disk = [ 'file:/path/to/your/disk,hda,w', 'file:/path/to/your/file.iso,hdc: cdrom,r']
xenguest-install shouldn't ever be writing out a cdrom= line in the config; we use it only for the install and that's all done via libvirt. Can you provide the config you're getting spit out?
