Exactly my point of view.

I have read the qemu plans
(http://wiki.qemu.org/Features/LiveBlockMigration) which seems to me
they are taking an approach centered around a VM meaning they will
perform migration where the entire VM is moved accordingly. I was
thinking more about added a extra button under the hardware tab which
will be available when a harddisk is having focus. The name will
obviously be 'migrate' or 'move'. When the user presses the button an
overlay menu should open showing the following:

Disk: The name
Target: A drop-down list displaying available shared storage

I will not show a checkbox for choosing online since this will be
implicit - connected to a running instance means online, offline
otherwise.

Next part will be to move the disk to the new location and change
vmid.config accordantly.

Finish by refreshing the GUI with the new information.
