Re: [libvirt] PATCH: Fix booting QEMU off CDROM

KVM supports an alternate syntax for indicating a boot device when the -drive parameter is available. Instead of -boot c, it allow 'boot=on' to be set for the -drive parameter. Unfortauntely it turns that this doesn't work with certain CDROM images, in particular Fedora 9 https://bugzilla.redhat.com/show_bug.cgi?id=452355 Discussion with upstream indicates we're lucky it ever worked at all for CDROM media. So this patch removes use of the boot=on flag for CDROM devices. NB, even when we added boot=on, we always still added -boot d param too, so merely removing the boot=on flag is sufficient to make it work again.
