Re: [PATCH 00/10] Introduce virtio-mem <memory/> model

Technically, this is another version of: https://www.redhat.com/archives/libvir-list/2020-December/msg00199.html But since virtio-pmem part is pushed now, I've reworked virtio-mem a bit and sending it as a new series. For curious ones, David summarized behaviour well when implementing virtio-mem support in kernel: https://lwn.net/Articles/755423/ For less curious ones: # virsh update-memory $dom --requested-size 4G adds additional 4GiB of RAM to guest; # virsh update-memory $dom --requested-size 0 removes those 4GiB added earlier. Patches are also available on my GitLab: https://gitlab.com/MichalPrivoznik/libvirt/-/tree/virtio_mem_v3
