v4 of: https://listman.redhat.com/archives/libvir-list/2021-June/msg00679.html diff to v4: - Rebased onto current master - Worked in David's suggestions, e.g. rename from <actual/> to <current/>, implemented offline memory update, implemented --node argument to virsh update-memory-device, prealloc is OFF and reserve is ON for virtio-mem Some suggestions are left as future work. For instance: - Don't require memory slots because virtio-mem lives on PCI bus anyway - Allow path backed backend for virtio-mem - support .prealloc for virtio-mem object (not memory-backend-* !)
