Bug Description

I tried starting nova-network, but I end in the following error. I couldn't find a flag to change the domain in nova-network --help.

relevant settings in /etc/nova/nova.conf:
--network_manager=nova.network.manager.VlanManager
--fixed_range=192.168.0.0/24
--network_size=5000

the string "novalocal" is hardcoded in nova/network/linux_net.py in the method _host_dhcp(). I don't like this and I suggest using a flag.

and dnsmasq needs the parameter --domain=, this fixes the problem with the unknwon domain. i extended the patch.
