The same applies to virtio-mem (there are MM interfaces in Windows used by Hyper-V that could allow to make it work, however they are marked as not supported). At least for virtio-mem, only Linux is the focus for now. We can't fix closed-source operating systems, Microsoft itself would have to provide new interfaces, or mark the existing once as supported. > > Thanks > Kevin > > -- Thanks, David / dhildenb
