Hi, this is an idea that is based on Andrea Arcangeli's original idea to host enforce guest access to memory given up using virtio-balloon using userfaultfd in the hypervisor. While looking into the details, I realized that host-enforcing virtio-balloon would result in way too many problems (mainly backwards compatibility) and would also have some conceptual restrictions that I want to avoid.
