From: "Daniel P. Berrange" <berrange@redhat.com> When opening a stream to a device which is a TTY, that device may become the controlling TTY of libvirtd, if libvirtd was daemonized. This in turn means when the other end of the stream closes, libvirtd gets SIGHUP, causing it to reload its config. Prevent this by forcing O_NOCTTY on all streams that are opened Signed-off-by: Daniel P.
