As far as I know, nova now only support disk snapshot of vm, but libvirt can snapshot memory of vm. Is there a plan to add this feature?

In OpenStack terminology, an instance snapshot is an image. Since an image doesn't include RAM contents, I'd say the answer is "never".

On the other hand, openstack server suspend saves an instance's memory to disk without creating an image.
