Sounds like we have two use cases :-) I am not seeing anything against it but I wonder if other virtualization offerings would benefit from this as well? As in would it make sense to export the virtio-ballon or the microsoft one as well? And perhaps have an unified API? So that the ballloon drivers register and then have a "virt_mem_set_new_target" exported? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
