Even when not using libvirt for a reason or another I usually hook my
virtual machines into virbr0 (libvirt default network).

I had the opposite problem.  Needed to use multiple bridges and have
some VMs behind NAT without a bridge (private IPs), and some using
separately firewalled bridges (needed to behave like real attached
hardware with their original MACs, but be firewalled).

No problem in theory. libvirt should detect existing bridges and allow you to attach virtual machines to them. So you can setup bridges and firewalling for them using usual distro tools and use them for virtual machines.

In practice I've seen this not working correctly in the past, i.e. my br0 didn't pop up in the virt-manager nic setup page.
