   Severity: grave   
      
   I'm not sure I know exactly what's going on here. I marked this bug as grave   
   at it makes KVM completely unusable unless you don't use networking. I believe   
   Debian unstable moved from iptables to nftables a while ago, which broke   
   libvirt networking. I've    
   been getting around that by using an older kernel (6.17.x, don't remember   
   exactly which one) but that stopped working after I upgraded yesterday.   
      
   I get the following error when I try to start the default (NAT) network:   
   $ sudo virsh net-start default   
   error: Failed to start network default   
   error: internal error: Failed to run firewall command iptables -w --table   
   filter --list-rules:   
      
   Running that command manually I get:   
   $ sudo iptables -w --table filter --list-rules   
   modprobe: FATAL: Module ip_tables not found in directory /lib/mo   
   ules/6.18.12+deb14-rt-amd64   
   iptables v1.8.12 (legacy): can't initialize iptables table `filter': Table   
   does not exist (do you need to insmod?)   
   Perhaps iptables or your kernel needs to be upgraded.   
      
   Again, I'm not sure exactly what's going on here. It's possible this issue was   
   already reported, but I couldn't find it.
