While 'usb-bot' and 'usb-storage' are ABI and migration compatible for disks it's not the case for cdroms. When migrating from a new config using 'usb-bot' to an older daemon which would use 'usb-storage' the guest os will get I/O errors. Thus we must properly fill in models for 'usb' disks so that cdroms can be handled properly. When parsing XML fill in the models and drop the appropriate models when formatting migratable XML. The logic is explained in comments in the code. Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Jiri Denemark <jdenemar@redhat.com>
