I have already created a post for this on the Arch Linux Forum two days, but I didn’t recieve any reply there, so I’m trying it here.

I have multiple KVM virtual machines thatI use on a semi regular basis. After reinstalling dnsmasq, because it wasn’t installed for some reason, I get the error message that network default is not active every time I try to boot one of them.

Running virsh net-start default doesn’t solve the problem though, as it outputs error: Failed to start network default error: internal error: Child process (VIR_BRIDGE_NAME=virbr0 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper) unexpected exit status 2: dnsmasq: failed to create listening socket for 192.168.122.1: Address already in use

I don’t know how to proceed from here and I couldn’t really find anyone that ran into the same problem.

Any advice would be appreciated. Thank you in advance.

    I had the exact same issue! I was going crazy troubleshooting this, anyway it turned out to be the firewall on my arch install. I disabled ufw and everything started working as usual. I really should enable the firewall again and check what rules are screwing it up.
