I've observed this failed assertion:
libxl_event.c:2057: libxl__ao_inprogress_gc: Assertion `ao' failed.
AFAICT, this is happening in qmp_proxy_spawn_outcome where
sdss->qmp_proxy_spawn.ao is NULL.
The out label of spawn_stub_launch_dm() calls qmp_proxy_spawn_outcome(),
but it is only in the success path that sdss->qmp_proxy_spawn.ao gets
set to the current ao.
qmp_proxy_spawn_outcome() should instead use sdss->dm.spawn.ao, which is
the already in-use ao when spawn_stub_launch_dm() is called. The same
is true for spawn_qmp_proxy().
With this, move sdss->qmp_proxy_spawn.ao initialization to
spawn_qmp_proxy() since its use is for libxl__spawn_spawn() and it can
be initialized along with the rest of sdss->qmp_proxy_spawn.
Fixes: 83c845033d ("libxl: use vchan for QMP access with Linux stubdomain")
