After posting your network configuration, I see you are using a different subnet for Libvirt. This is wrong, especially considering that you use 192.168.2.100 on the bridge interface that you use for Libvirt, while the virtual machines (that are on the same bridge) get allocated 192.168.122.0/24. Anyway, if you insist on doing double NAT, reflect this in ...

EDIT: It turns out that OP uses a bridge with two different subnets. This was not clear from the question before an edit, and this answer was written with the assumption that both ends on the bridge have the same subnet. You are not using NAT on your Libvirt box.

You can't use switch port security on the Cisco since all the VMs will be sharing a physical switch port. And you can't use Linux iptables because the traffic is being bridged, not routed, through the hypervisor machine. But you can emulate switch port security on the hypervisor with Linux ebtables, which is a lesser-known layer 2/3 firewall on the Linux ...

I have been able to make dnsmasq 'see' the newly added IP-MAC mapping by simply sending a -HUP signal to the dnsmasq process. After that, rebooting the new guest was enough to have the correct IP assigned to it, without the need to restart libvirtd nor the network itself. The official libvirt documentation ...
