Libvirt's monitor is trying to read from already-opened monitor fd.
Qemu has crashed, perhaps unable to find some backing store, perhaps for
some other reason.  /var itself is ok - even it it had gotten
overmounted, libvirt is reading from an fd and the overmount wouldn't
matter.

We need to figure out why qemu crashed.  There may be useful info in
/var/log/libvirt/qemu/ipcop-clone.log

Because yours has a different cause, and is therefore a different bug
with similar symptoms.  Globbing the info with that from other bugs
makes it harder to cleanly reason about it and minimizes our chances of
finding the root cause.
