Allow a VM with a locally-attached disk to live-migrate both VM and disk to another host
Note that this feature is already available in XCP 1.6: the request here is to implement this functionality in xl.

This already works in the most recent XenServer release, and requires that the host be running. The "Dundee" pre-release has added this option for hosts that are not running (just tested this yesterday).
