Statically Defining a Network
by richard.schmitt＠starlab.io 13 Jun '24

We install libvirt in a AlmaLinux 9 Kickstart file. The version of libvirt we are using is 10.0.0. What we'd like to do is to statically define a network in the kickstart file without having to run `virsh net-define`. In other words, we had hoped that by installing a <network>.xml file in /usr/share/libvirt/networks, that that network would be recognized by libvirt the first time the system is booted. This does not appear to be the case. Is there a way to statically define libvirt networks without needing to run 'virsh net-define'? Thanks

However I'm not sure how to see if that is running. Like I opened Systems Monitor and can't find any process with that name. > > So may be that's the problem? Well, have you restarted the network? You need the 'virsh net-destroy default && virsh net-start default' combo to restart it. After that you should see dnsmasq process, e.g. via 'ps axf | grep dnsmasq'. Michal
