[PATCH v2 0/3] python/qemu/machine: fix potential hang in QMP accept

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

As reported earlier by Richard Henderson ("virgl avocado hang" thread), avocado
tests may hang when QEMU exits before the QMP connection is established.

v2:
 - use a socketpair() for QMP (instead of async concurrent code from v1) as
   suggested by Daniel Berrange.
 - should not regress (hopefully)

Marc-André Lureau (3):
  python/qmp/protocol: add open_with_socket()
  python/qmp/legacy: make QEMUMonitorProtocol accept a socket
  python/qemu/machine: use socketpair() for QMP by default
