[libvirt] [RFC PATCH 10/10] libvirtd: fix crash on termination
From: Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com>
[NB: Taken from earlier patch, although I'm not sure this patch
would be necessary any more...]
The problem is incorrect order of qemu driver shutdown and shutdown
of netserver threads that serve client requests (thru qemu driver
particularly).
Net server threads are shutdown upon dispose which is triggered
by last daemon object unref at the end of main function. At the same
time qemu driver is shutdown earlier in virStateCleanup. As a result
netserver threads see invalid driver object in the middle of request
processing.
Let's move shutting down netserver threads earlier to virNetDaemonClose.
Note: order of last daemon unref and virStateCleanup
is introduced in 85c3a182 for a valid reason.
