There is a postparse callback which deals with _ABSENT (see commit
8cd7196974d):


static int
virDomainDiskDefPostParse(virDomainDiskDefPtr disk,
                          const virDomainDef *def,
                          virDomainXMLOptionPtr xmlopt)
{
    ...
    if (disk->src->type == VIR_STORAGE_TYPE_NVME) {
        if (disk->src->nvme->managed == VIR_TRISTATE_BOOL_ABSENT)
            disk->src->nvme->managed = VIR_TRISTATE_BOOL_YES;
    }
    ...
}

But maybe the callback is not called from tests where virStorageSource
is parsed directly?
