I’m wondering whether there is any difference between VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON and ‘memory’ member from virDomainInfo structure.

Based on the documentation those values should correspond to current balloon and memory used by the domain respectively.

Is it always the case that those values will be equal?


Is there a reason why maximum memory allowed (‘maxMem’ from virDomainInfo structure) cannot be retrieved from virDomainMemoryStats API?

It seems that it’s required to call 2 different APIs to get all memory metrics for a domain.
