sudo virsh net-start default fails on Debian 11 (Bullseye)
Software environment
- Operating system: Debian 11
- Architecture: x64
- kernel version: 5.10.0-13
- libvirt version: 8.0.0
- Hypervisor and version: QEMU 7.1.0
Description of problem
It is not possible to start virtual network 'default' because of replacement of iptables in Debian with nftables.
Steps to reproduce
Run
sudo virsh net-start default
/usr/sbin/iptables -w --table filter --insert LIBVIRT_INP --in-interface virbr0 --protocol tcp --destination-port 67 --jump ACCEPT
: iptables v1.8.7 (nf_tables): unknown option "--destination-port"
Try `iptables -h' or 'iptables --help' for more information.
See https://blog.zentria.company/posts/its-2021-nftables-still-does-not-integrate/
Unfortunately, I must use nftables. Iptables are not compiled into my kernel. How do people run KVM on Debian ?
