[libvirt-users] network configuration for guest specific dns-servers

Hello,

similar to how one can configure guest specific IP addresses via mac
addresses:
<ip address="192.168.122.1" netmask="255.255.255.0" localPtr="yes">
  <dhcp>
    <range start="192.168.122.100" end="192.168.122.254"/>
    <host mac="00:16:3e:77:e2:ed" name="foo.example.com" ip="192.168.122.10"/>
    <host mac="00:16:3e:3e:a9:1a" name="bar.example.com" ip="192.168.122.11"/>
  </dhcp>
</ip>

We would like to configure guest specific dns-servers as would be done
with the --dhcp-option of dnsmasq.  I was expecting to be able to do
something like:

    <host mac="00:16:3e:77:e2:ed" 
	name="foo.example.com" 
	ip="192.168.122.10" 
	dhcp-option="dns-server,127.0.0.1" />

but it seems that this isn't the correct approach, as virsh net-edit
default removes that attribute definition.

Could someone point me to the correct documentation?

Thank you!
David Ayers
