Subject: [Qemu-devel] [PULL v2 for-2.4 v2 2/7] qemu-timer: initialize "timers_done_ev" to set
Date: Wed, 22 Jul 2015 12:43:40 +0100	[thread overview]
Message-ID: <1437565425-29861-3-git-send-email-stefanha@redhat.com> (raw)
In-Reply-To: <1437565425-29861-1-git-send-email-stefanha@redhat.com>

From: Paolo Bonzini <pbonzini@redhat.com>

The normal value for the event is to be set.  If we do not do
this, pause_all_vcpus (through qemu_clock_enable) hangs unless
timerlist_run_timers has been run at least once for the timerlist.
This can happen with the following patches, that make aio_notify do
nothing most of the time.
