New subject: [libvirt] [PATCH 5/5] qemu: domain: Forbid copy_on_read option also for floppies
Using copy_on_read for removable disks is a hassle. It also does not
work for CDROMs at all as the image is supposed to be read-only and we
might ignore it for floppies when they are started as empty. Forbid it
for floppies completely rather than trying to support what probably
nobody is using.
