Re: [libvirt] [PATCH v5 04/24] conf: add APIs to convert virDomainNetDef to virNetworkPortDef

Helper APIs are needed to - Populate basic virNetworkPortDef from virDomainNetDef - Set a virDomainActualNetDef from virNetworkPortDef - Populate a full virNetworkPortDef from virDomainActualNetDef Signed-off-by: Daniel P. Berrangé <berrange(a)redhat.com&gt;
