The bandwidth plug and unplug functions were assuming that an interface's bandwidth setting was always specified directly in the domain's <interface> definition, but that's not necessarily true - it could have been obtained from a <portgroup> definition in the network definition. This patch fixes those functions to use virDomainNetGetActualBandwidth(), which gets the bandwidth pointer from iface->data.network.actual if it exists, otherwise returns iface->bandwidth. --- src/network/bridge_driver.c | 19 +++++++++---------- 1 file changed, 9 insertions(+), 10 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index c3cb63d..6f3c839 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -4518,7 +4518,7 @@ networkCheckBandwidth(virNetworkObjPtr net, { int ret = -1; virNetDevBandwidthPtr netBand = net->def->bandwidth; - virNetDevBandwidthPtr ifaceBand = iface->bandwidth; + virNetDevBandwidthPtr ifaceBand = virDomainNetGetActualBandwidth(iface); unsigned long long tmp_floor_sum = net->floor_sum; unsigned long long tmp_new_rate = 0; char ifmac[VIR_MAC_STRING_BUFLEN]; @@ -4597,6 +4597,7 @@ networkPlugBandwidth(virNetworkObjPtr net, unsigned long long new_rate = 0; ssize_t class_id = 0; char ifmac[VIR_MAC_STRING_BUFLEN]; + virNetDevBandwidthPtr ifaceBand = virDomainNetGetActualBandwidth(iface); if ((plug_ret = networkCheckBandwidth(net, iface, &new_rate)) < 0) { /* helper reported error */ @@ -4625,11 +4626,8 @@ networkPlugBandwidth(virNetworkObjPtr net, goto cleanup; } - plug_ret = virNetDevBandwidthPlug(net->def->bridge, - net->def->bandwidth, - &iface->mac, - iface->bandwidth, - class_id); + plug_ret = virNetDevBandwidthPlug(net->def->bridge, net->def->bandwidth, + &iface->mac, ifaceBand, class_id); if (plug_ret < 0) { ignore_value(virNetDevBandwidthUnplug(net->def->bridge, class_id)); goto cleanup; @@ -4638,11 +4636,11 @@ networkPlugBandwidth(virNetworkObjPtr net, /* QoS was set, generate new class ID */ iface->data.network.actual->class_id = class_id; /* update sum of 'floor'-s of attached NICs */ - net->floor_sum += iface->bandwidth->in->floor; + net->floor_sum += ifaceBand->in->floor; /* update status file */ if (virNetworkSaveStatus(NETWORK_STATE_DIR, net) < 0) { ignore_value(virBitmapClearBit(net->class_id, class_id)); - net->floor_sum -= iface->bandwidth->in->floor; + net->floor_sum -= ifaceBand->in->floor; iface->data.network.actual->class_id = 0; ignore_value(virNetDevBandwidthUnplug(net->def->bridge, class_id)); goto cleanup; @@ -4666,6 +4664,7 @@ networkUnplugBandwidth(virNetworkObjPtr net, { int ret = 0; unsigned long long new_rate; + virNetDevBandwidthPtr ifaceBand = virDomainNetGetActualBandwidth(iface); if (iface->data.network.actual && iface->data.network.actual->class_id) { @@ -4680,13 +4679,13 @@ networkUnplugBandwidth(virNetworkObjPtr net, if (ret < 0) goto cleanup; /* update sum of 'floor'-s of attached NICs */ - net->floor_sum -= iface->bandwidth->in->floor; + net->floor_sum -= ifaceBand->in->floor; /* return class ID */ ignore_value(virBitmapClearBit(net->class_id, iface->data.network.actual->class_id)); /* update status file */ if (virNetworkSaveStatus(NETWORK_STATE_DIR, net) < 0) { - net->floor_sum += iface->bandwidth->in->floor; + net->floor_sum += ifaceBand->in->floor; ignore_value(virBitmapSetBit(net->class_id, iface->data.network.actual->class_id)); goto cleanup; -- 1.7.11.7
