Thanks Conny! I'll wait for more feedback before I open a github issue / request a vote.On Mon, Sep 20 2021, David Hildenbrand <david@redhat.com> wrote:Looking into supporting virtio-mem a) without a shared zeropage for the memory backing of the device -- not allowing the driver to read unplugged memory b) on architectures with memory properties for RAM (e.g., s390x with storage keys and storage attributes) requires extension of the spec to handle both cases cleanly and describe the expected semantics. I'll open a github issue soon; in the meantime, I'll work on the actual implementation in QEMU and Linux.LGTM, but would like a second opinion.
