Hi there, I've uploaded version 4.0.1 of xen-qemu-dm that fixes a quite nasty bug fixed by upstream: read-only file images were in fact write-also. The debian packaging didn't change at all, it just includes the 2 last commits here: http://xenbits.xensource.com/gitweb?p=qemu-xen-4.0-testing.git;a=summary As I believe this is an important bug/feature fix, I think version 4.0.1 should be unblocked.
