KVM static IP lease / DHCP config

Power VM down

virsh  dumpxml  $VM_NAME | grep 'mac address'
virsh  net-list
virsh  net-edit  $NETWORK_NAME  #(default?)


<dhcp>
  <range start='192.168.122.100' end='192.168.122.254'/>
  <host mac='[MAC]' name='vm1' ip='192.168.122.xy'/>
...
..
.
</dhcp>
virsh  net-destroy  $NETWORK_NAME  
virsh  net-start    $NETWORK_NAME  

Host reboot should be unnecessary…
