perhaps we have a misunderstanding... yogev wrote in the bug: 
configuration doesn't write logs -> no libvirt log exists :)
libvirtd.conf currently has # for any logging  - which means nothing is 
logged for libvirt, no debug, info, warn or error will be logged at all 
because the logs for libvirt are disabled.
we did have an error where a libvirt domain was killed and I wanted to 
look at the libvirt log to see what happened and this is when we found 
no log exists...
after we manually changed the libvirtd.conf file a libvirt log was 
created and than we also changed the log level to debug so that we can 
debug something :)

basically, we can debate the debug log level issue but can we agree that 
a log should exist and log erros?
