We prefer explicit tests for (non-)zero values for anything that's numeric (e.g. not a boolean or pointer). Also there's no point to continue if 'n' is zero here. Usually copy functions also allocate memory; document that this one does not. Since 'virDomainThrottleGroupUpdate' below has weird semantics of not doing anything when given group doesn't exist consider merging these two together. This will also prevent the situation when virDomainThrottleGroupAdd is called on an existing definition which would add it without checking that it already exists and none of the other functions consider that scenario. At the very least document that this does absolutely no checking. Replace by Update corresponding throttle group in @def new config @info. If a throttle group with given name doesn't exist this function does nothing. Replace by: Delete throttle group @name in @def. Since this is not the same code that parses/formats the <disk> throttling definition add a comment to both places stating that anyone adding fields must also change the other place as well. 'nthrottlegroups' is 'size_t' (see below) so 'n' ought to be as well. [ ^^^^ ]

If it's just meant to free the contents please use the 'Clear' naming instead of 'Free' This doesn't report error ... And you break out here .. ... and here too so this function will not report an error. Use virXMLPropStringRequired instead if the function field is required. virDomainDiskDefFormatThrottleFilters below checks only the 'nthrottlefilters'. In fact all of the above check is not needed as the loop simply won't find anything in a 0 sized array and return NULL at the end. Add a separator comment here here as node name is a qemu driver implementation detail and not a configuration field. This will also later have to be serialized into the qemu driver's disk private data (I didn't check if it is). Rest looks okay to me.

[...] I don't think we should do the 'change a subset of' semantics any more. It was proven that it doesn't make sense. Specifically it's not possible to distinguish between "I don't want to change this field" and "I want to delete/revert to default for this field". The users must be instructed to always post the full required config. 11.1.0 For getter APIs you can't set both because there's no way the API can return both configs at once. The actual value of 'nparams' at call doesn't matter, thus makes no sense to be logged. At the same time, 'group' which is a much more useful info is not logged. [...] This also must correspond to the proper version and this one can't be fixed later. This is a weird construction, 'group' is supposed to be a nonnull string, so why should it ever be NULL? Spacing broken. Also 'group' is a mandatory argument, so why it's being checked? This line makes no sense to me. Alignment of args seems to be broken. 11.1.0 Deletion of the throttle group needs to have same ACLs as the SET, thus also the 'save' perms need to be copied.

As noted, this getter is mostly pointless as it just returns what should have been recorded in the XML in the first place so I don't think this makes too much sense to have. As noted you can't really combide VIR_DOMAIN_AFFECT_LIVE VIR_DOMAIN_AFFECT_CONFIG as it'll return garbage. The rest looks reasonable.

Referencing 'attach-disk' makes no sense. Stick to mentioning that it's used by a disk. Missing note that --live and --config together makes no sense. This is querying throttle groups; not block devices. This will most likely need to be reimplemented by querying the data from the XML as the API itself IMO doesn't make too much sense to exist as it simply queries what we've set.

As noted in our guidelines tests must pass after every commit, so this kind of fix up later on is not the correct fix. I'll start a proper review of these patches once I close up few other things, so please be patient. This feature is rather complex and thus potentially involves maintenance burden on the maintainers so I'll need to make sure it's as minimal as possible.
