Re: [libvirt] Inconsistency with documentation virDomainGetMaxMemory(NULL)



Stefan de Konink schreef:
 From docs:

Retrieve the maximum amount of physical memory allocated to a domain. If domain is NULL, then this get the amount of memory reserved to Domain0 i.e. the domain where the application runs.

Doing it the 'proper' way gives an even more interesting answer:

    virDomainPtr domu = virDomainLookupByID(conn, 0);
    printf("%ld\n", virDomainGetMaxMemory(domu));
