Hey folks,just set up a new KVM host on Bullseye and ran into the same problems. Our automation purges iptables after setting up nftables to have clean slate which also would remove libvirt-daemon-system here.
As I don't use any networking related features offered by libvirt I would consider it great if there wouldn't be a hard dependency on any related packages. Maybe the dependency on iptables could become a recommends?
Thanks and best regards, Max
