[Rdo-list] libvirtd default configuration

[Dafna Ron]

Perry,

in current setups nothing is logged at all, i.e there is no libvirt log 
until we configure the conf file to log something...
And sorry, but I disagree with Dan... working on ovirt for a few years I 
can tell you that the libvirt logs are in debug and are simply rotated 
and deleted if space is run out or after 30 days.
These are simple debugging tools that admin's need and if someone 
decided that they don't need them - that's ok, but our premise should be 
that we want to catch events since they cannot always be reproduced...

this is from an ovirt host where log level is debug and logs are rotated:
