[libvirt] [PATCH v2 0/4] qemu: use FD passing for chardev UNIX sockets

This series makes use of the chardev fd passing arriving in QEMU 2.12
to get rid of the startup race wrt opening the QEMU monitor. It is
actually enabled in all chardev UNIX sockets for sake of having the
same codepath everywhere, but is only important for the monitor socket.

Daniel P. Berrangé (4):
  qemu: probe for -chardev 'fd' parameter for FD passing
  qemu: support passing pre-opened UNIX socket listen FD
  qemu: don't retry connect() if doing FD passing
  qemu: remove pointless connect retry logic in agent
