Hi,
I followed this tutorial:
https://trisquel.info/en/wiki/virtualization-using-kvm
I tried both fixed and DHCP, but none works for me.
I'm stuck here,
sudo ifdown br0
It gives me:
ifdown: interface br0 not configured
Tried to searx it, and the only thing I barely understood was the file
at "/run/network/ifstate"
which only contains "lo=lo"
I tried to add randomly "eth0=eth0" and "br0=br0", but no success.
By the way, I'm not linked through the internet.
So I also tried to modify the network part (/etc/network/interfaces)
where it says
"bridge_ports eth0"
to "all" instead of "eth0".
Doesn't work either.
I also restarted the network services in between.
