Hello,

Few months ago, I have no issue using Qemu - Virt Manager - Libvirt

Due to work, I havent use my system for 3 months. And now I am back and after updating full, I cant get it to ran or start a vm, error occured as no network

when I start the virtual network manually, I have this error

Code:
Error starting network 'default': internal error: Failed to apply firewall command '/sbin/tc filter add dev virbr0 prio 2 protocol ip parent 1: u32 match ip dport 68 ffff action csum ip and udp': Error: Failed to load TC action module.
We have an error talking to the kernel
