Hypothetical scenario:

  • 2 machines running Hyper-V Server 2008 R2
  • configured as a cluster
  • VHD files stored on each machine

Is it possible to do a live migration without using shared storage? I imagine that it could take a very long time to copy the VHD files, but I want to know if Hyper-V has the intelligence to keep plugging along with a live migration that might last hours or days.

No, live migration requires shared storage (on both Hyper-V or VMware ESX).

KVM live migration has an option to enable block migration, which doesn't require the shared storage. Available starting from qemu-kvm-0.12
