Hi, I was trying to pass ip address to scripts/vif-bridge by putting <ip address=""/> in guest config xml file, however, I found that libxlMakeNic(which located in libxl/libxl_conf.c:956) doesn't set x_nic->ip. So I patched myself but I'm not so sure about VIR_DOMAIN_NET_TYPE_ETHERNET. It seems like vif-route, correct?  Here is my patch: diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 0555b91..0effc59 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -1047,10 +1047,18 @@ libxlMakeNic(virDomainDefPtr def,              if (VIR_STRDUP(x_nic->bridge,                             virDomainNetGetActualBridgeName(l_nic)) < 0)                  return -1; -            /* fallthrough */ +            if (VIR_STRDUP(x_nic->script, l_nic->script) < 0) +                return -1; +            if (VIR_STRDUP(x_nic->ip, l_nic->data.bridge.ipaddr) < 0) +                return -1; +           break;          case VIR_DOMAIN_NET_TYPE_ETHERNET:              if (VIR_STRDUP(x_nic->script, l_nic->script) < 0)                  return -1; +            if (VIR_STRDUP(x_nic->ip, l_nic->data.ethernet.ipaddr) < 0) +                return -1; +            if (VIR_STRDUP(x_nic->gatewaydev, l_nic->data.ethernet.dev) < 0) +                return -1;              break;          case VIR_DOMAIN_NET_TYPE_NETWORK:          { Regards, Jihoon
