Re: [libvirt] [PATCH 2/4] Avoid bogus I/O event errors when closing the QEMU monitor

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; After calling qemuMonitorClose(), it is still possible for the QEMU monitor I/O event callback to get invoked. This will trigger an error message because mon->fd has been set to -1 at this point. Silently ignore the case where mon->fd is -1, likewise for mon->watch being zero. Signed-off-by: Daniel P.
