[Libvir] [patch 0/9] Preliminary patches for virtual networks support

Hi, Yesterday I went ahead and committed the virtual networks support in time for DV to make a release. I thought it'd be worth sending them here so that people can look over them and hopefully sport any problems. So, here's the first batch - various fixes to the qemu support and small bits of re-factoring in other parts of libvirt. Cheers, Mark. --
