Hi,

As $subject, e.g. the monitor is being used by netcat.

Is it expected? Should we only skip to reconnect the domain monitor which is being locked by other app with a timeout specified on "qemuMonitorOpenUnix" (it blocks when trying to connect to the unix socket)? so that it can get a connection, and could manage other domains.

How to produce:

1) # service libvirtd stop 2) # nc -U /var/lib/libvirt/qemu/$guest.monitor 3) # virsh (hangs forever if nc process is not killed)

This is user error. Allowing the user to connect to the QEMU monitor for any libvirt managed QEMU instances is *not* supported while libvirtd is running. They must remove their 'nc' process before starting libvirtd again.
