- pzmarzly 4y agoThe mechanism is called balooning and technically doesn't need cooperation on guest kernel side (but it makes everything much smoother). Not idea about HyperV, but it is implemented e.g. in virtio https://pmhahn.github.io/virtio-balloon/ https://pmhahn.github.io/virtio-balloon/ . You can google some failed experiments to add it to qemu
