libvirtd from git segfaults on shutdown in _dbus_warn_check_failed
Last modified: 2013-03-04 12:16:43 EST
Description of problem:
libvirt compiled from git (55bfd020d8d9de40977832c4762728090df2bee3).
Run the daemon like this:
$ ./run gdb --args ./daemon/libvirtd --timeout 30
Run libguestfs-test-tool against this daemon so that a single
transient guest is created and destroyed.
Wait 30 seconds for libvirtd to timeout and exit.

Yep, I've just seen that problem too & am investigating it
Oh btw the problem likely exists in previous libvirt, but we were missing the virStateCleanup call for a few releases, which would have avoided triggering the problem

Fix nwfilter driver reload/shutdown handling when unprivileged
Although the nwfilter driver skips startup when running in a
session libvirtd, it did not skip reload or shutdown. This
caused errors to be reported when sending SIGHUP to libvirtd,
and caused an abort() in libdbus on shutdown due to trying
to remove a dbus filter that was never added
I'm backporting this to v0.10.2-maint, and leaving it in POST until F18 picks up the fix.
