This patch plumbs the virtio-pmem device to the VMM. By adding a new command line option "--pmem", we can now expose some persistent memory to the guest OS, backed by the provided source. The point of having such support in cloud-hypervisor is to be able to share some memory between the host and the guest as DAXable. One interesting use case is to boot directly from an image passed through virtio-pmem, instead of going through virtio-blk. This can allow good performances while avoiding the guest cache, which would prevent the VM memory footprint from growing too much.
