Please note that some people use the balloon for actual memory unplug - so initiating to deflate the balloon under any circumstances is undesired. It's different with "VIRTIO_BALLOON_F_DEFLATE_ON_OOM" being set - however that is barely the case (at least in the setups I know :) ). So yes, free page reporting is a different thing, because it really is used to "hint" and not to "agree to unplug" in any scenario. -- Thanks, David / dhildenb _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
