Ah, I just find that autoDumpPath is for watchdog event to auto-dump a
guest.  But I think the files libvirtd put in the cache directory
(except capabilites) are just temporary files instead of cache files.
So IMHO, a subdir in the cache directory is also not the perfect path
for these files.  How about putting these files in the pre-domain dir
(e.g. /var/lib/libvirt/qemu/domain-1-test)?
