I will second Corey's request - we've been working to make sure that dynamic memory and other features of Hyper-V are first class experiences on Linux, if you can share details on what issues and what versions you had them on that would be really helpful.
Hi Justin,
We are doing most of our working in a branch right now (https://github.com/microsoft/docker/tree/jjh-argon), as we stabilize the Windows Server Container and Hyper-V Container foundation the work we are doing to develop new drivers into the docker engine will stabilize and we’ll be pushing it upstream.
