This driver provides access to virtio-mem paravirtualized memory
devices, allowing to hotplug and hotunplug memory.
This driver was only tested under x86-64 and arm64, but should
theoretically work on all architectures that support memory hotplug
and hotremove.
This driver currently only supports x86-64 and arm64. Although it
