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?
