Subject: Re: [PATCH RESEND v2 0/5] virtio-mem: VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE and interaction with memory properties

Looking into supporting virtio-mem
a) without a shared zeropage for the memory backing of the device --

b) on architectures with memory properties for RAM (e.g., s390x with

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.

Okay, let's request a vote to get this integrated:

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/118

Thanks for the review Conny!
