[libvirt] [PATCH 07/10] network: Bridge - don't offer dnsmasq DHCP services when DHCP relay is enabled



From: TJ <linux iam tj>

When dnsmasq's DNS services are required but the network is configured
to use a DHCP relay agent (other than dnsmasq's proxy services) the
configuration generated for dnsmasq should not enable DHCP services.
