2014-05-25virtio-balloon: return empty data when no stats are availableJán Tomko1-2/+3
If the guest hasn't updated the stats yet, instead of returning an error, return '-1' for the stats and '0' as 'last-update'. This lets applications ignore this without parsing the error message. Related libvirt patch and discussion: https://www.redhat.com/archives/libvir-list/2014-May/msg00460.html Tested against current upstream libvirt - stat reporting works and it no longer logs errors when the stats are queried on domain startup. (Note: libvirt doesn't use the last-update field for anything yet) Signed-off-by: Ján Tomko <jtomko@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.
