Okay, applied after having rebased the previous patch and fixed an
array indexing problem in getIPv4Addr() after the ntoh conversion.
This fixes 524280 and with the usual default network we have
/usr/sbin/dnsmasq --strict-order --bind-interfaces
--pid-file=/var/run/libvirt/network/default.pid --conf-file=
--listen-address 192.168.122.1 --except-interface lo --dhcp-range
192.168.122.2,192.168.122.254 --dhcp-lease-max=253
running,
Daniel
