Basically I am looking for the whole code patch that triggers the virtio_balloon. The trigger is QEMU's balloon command, which you can use if you invoke QEMU directly, or virsh's setmem command if you use libvirt.

Thanks Paolo. What's the user space tool / command to trigger the virtio_balloon functionality? Basically I am looking for the whole code patch that triggers the virtio_balloon.

Would you let me know who is the consumer if there's any? The virtio-balloon driver is in drivers/virtio/virtio_balloon.c. Right now it only does manual ballooning though, not automatic.
