I use the 'tap' net device with KVM to get my vm connect to the Internet. But I have to be root, or use 'sudo', which is inconvenient. I think I can put my user account into some group so I can access the net device without root privilege. I tried the netdev group, but does not work. My account is already in the kvm group.
What else should I do? Or is there any way to allow me using KVM freely without permission issue?
