Hello everyone, TL;DR: Is ist possible to provide a secondary DNS (e.g. 8.8.8.8) via DHCP in addition to the gateway (in my case 10.0.1.1)? I use libvirt to manage all my qemu-based VMs. I have set up a local NAT-network which includes all my VMs (and some physical servers integrated via VPN). Everything works fine, but ocassionally, I have to restart the network (when I add instances for example). In that case, my VMs loose their local network connection until I restart them. However, some instances can not be restarted at will and so a change in network configuration means they loose their local connectivity. However, they still have a second network device that has an external static IP. This IP can still connect and be connected to, so it is feasible to loose the connection on the local network. Unfortunately though, libvirt (through dnsmasq's DHCP) broadcasts itself as the only DNS. This results in name resolution going down. If I add e.g. 8.8.8.8 to resolv.conf, I can resolve names again (except local ones, of course). So it would be nice if the DHCP would directly supply additional DNS servers. For dnsmasq, I would add to the configuration something like dhcp-option=6,0.0.0.0,8.8.8.8 However, looking through the archive, I found that you guys prefer to keep it implementation agnostic and thus you do not provide the option to set this directly (since this is dnsmasq-only). So I was wondering if there is any way to achieve this with libvirt? Is there already an implemented way I could not find? Or is there maybe a *generic* option to provide some kind of extra-configuration specific to the implementation? Or is my only solution to make sure the clients manually add a second DNS by themselves?
