Hi,
Libvirt currently fails to start with dnsmasq >= 2.56.
since dnsmasq now bails out with empty arguments. See
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=613944
for the Debian bug and
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=589885
for the upstream reasoning.
Tested with 2.55 and 2.56. O.k. to apply?
Cheers,
-- Guido
