      <driver name='qemu' type='raw'/>
      <source file='/var/lib/libvirt/images/systemrescuecd-6.0.2.iso'/>
      <target dev='hdc' bus='ide'/>
      <readonly/>

sudo qemu-img create -f qcow2 /var/lib/libvirt/images/centos7.qcow2 15G

sudo iptables -t nat -A POSTROUTING -j MASQUERADE
or
firewall-cmd --zone=external --add-masquerade --permanent
firewall-cmd --reload

This helps avoid errors like: dracut-initqueue[688]: Warning: unknown network kickstart URL: ...
