When trying to update bandwidth limits on a running domain, limits get updated in our internal structures, however XML parser reads bandwidth limits from network 'actual' definition. Commiting this patch

This will set net->data.network.actual->bandwidth to NULL It's also remove it when net->bandwidth == NULL thus causing actual to be lost, which it doesn't seem is desired, but perhaps it is. Gues

Making this irrelevant, but I wonder if the < 0 here meant to do something else perhaps?

The above hunk needs some space formatting. Also since the virNetDevBandwidthCopy() has a if (!src) check, "(!net->bandwidth) ||" is unnecessary. if (net->type == VIR_DOMAIN_NET_TYPE_NETWORK) { virNetDevBandwidthFree(net->data.network.actual->bandwidth); if (virNetDevBandwidthCopy(&net->data.network.actual->bandwidth, net->bandwidth) < 0) goto cleanup } Whether this is what is "expected" is perhaps something Laine can answer...
