[Pkg-libvirt-maintainers] Bug#938929: Dependency problem with iptables and libvirt-daemon-system

[Daniel]

Dear maintainer,

this problem is still existing with Debian 11.2 and is really annoying. 
VMs are not started because network is not up. While starting the 
network we get

virsh# net-start route

erreur :Impossible de démarrer le réseau route
erreur :internal error: Failed to apply firewall rules 
/usr/sbin/iptables -w --table filter --list-rules: # Warning: 
iptables-legacy tables present, use iptables-legacy to see them
iptables v1.8.7 (nf_tables): table `filter' is incompatible, use 'nft' tool.

Same info for ip6tables.

We are using nftables and loading rule on boot with
nft flush ruleset && nft -f rules.file
If we remove iptables libvirt-daemon-system is removed too !

To get everything working well again after a reboot:

virsh# exit
sudo systemctl stop libvirtd
sudo nft flush ruleset
sudo apt reinstall libvirt-daemon-system (which will reinstall iptables too)
sudo systemctl start libvirtd
sudo virsh
virsh# net-start route

and now we can start all our VMs manually. Not quite what we expected 
when switching to nftables :(

Thanks for your feedback
