non-root bridge set-up on Fedora 39 aarch64

Hello- I'm somewhat new to the libvirt world, and I've encountered a problem that needs better troubleshooting skills than I have. I've searched Google/Ecosia and stackoverflow without finding a solution. I set up libvirt on an x86_64 system without a problem, but on my new aarch64 / Fedora 39 system, virsh doesn't seem to want to start virbr0 when run from my own user account: cel@boudin:~/kdevops$ virsh net-start default error: Failed to start network default error: error creating bridge interface virbr0: Operation not permitted cel@boudin:~/kdevops$ cat /etc/qemu/bridge.conf allow virbr0 cel@boudin:~/kdevops$ Where can I look next? -- Chuck Lever
