Vagrant stuck on Waiting for domain to get an IP address...

When you get stuck with "Waiting for domain to get an IP address..." while running a vagrant box with libvirt provider, you should look at your logs (`journalctl -f`) and you may find the following error :

dnsmasq-dhcp[]: DHCP packet received on virbr1 which has no address

This means there is no IP address on our bridge. A simple solution is : delete vagrant network :

sudo virsh net-destroy --network vagrant-libvirt
sudo virsh net-undefine --network vagrant-libvirt

Then, we can try to boot our box again:

vagrant destroy --force
vagrant up
