I've had some hardware trouble lately, with hard-drives failing with some VMs on these, and my Hyper-V Mover tool hase saved me a great deal of time.

I've had some time to improve it and this time, it is possible to attach and detach VMs from remote machines, and particularly those that are on Hyper-V Server machines.

I've created a page for this tool, the Hyper-V Virtual Machine Mover, version 1.0.1.0.

Still no sources available but they'll be available on CodePlex soon.
