[libvirt] patch for dnsmasq parameters is not complete

Although the patch with "--domain xxx --local=/xxx/" for dnsmasq command line parameters is good as far as it goes, it is not complete. As it is, dnsmasq will no longer forward names in its name-domain, but it will forward reverse lookup (IP address) queries. I am going to need to look at the code more. Instead of "--domain virt --local=/virt/" or just "--local=//" they need to look something like: "--domain virt --local=/virt/ --local=/122.168.192.in-addr.arpa/" or "--local=// --local=/122.168.192.in-addr.arpa/". I have dome some virtual testing and manually configured dnsmasq in a virtual machine and adding the second "--local" works rather well. Coming up with a new patch that works, that will take a lot more effort. Gene
