Public bug reported:
Libvirt is not robust against failures.
For some reason libvirt segfaulted on me (separate bug):
[12031.895269] libvirtd[1374]: segfault at 10 ip 00007f68357a4224 sp
00007fff49a8aed0 error 4 in libpthread-2.11.1.so[7f683579b000+18000]
upstart tried to restarts it but fails:

Jan 21 14:40:06 rhea init: libvirt-bin respawning too fast, stopped
only after I tried to manually start libvirtd I found out what the problem is:
r...@rhea:/var/log# sudo libvirtd
14:51:53.380: error : qemudWritePidFile:498 : Failed to open pid file
'/var/run/libvirtd.pid' : File exists
r...@rhea:/var/log# cat /var/run/libvirtd.pid
1374
Obviously libvirtd should have removed the stale pidfile (process not longer
running), by itself on
subsequent restart.
Furthermore an warning should have been emitted in some logfile, that the stale
pidfile was removed.
Best regards,
Arnd
