you can check dev mailing 2 or 3 week ago.

The main problem was with hot-unplug, and guest without acpi.
(removal was not working (notmal) but it's was breaking the nic or disk access.

Note since that I have improve the behaviour, and now it's safe for guests without acpi.

The only thing we need to add, is guest agent support, to verify that a disk/parition is not mounted before unplug.
(For windows it's ok without guest agent, acpi unplug will fail if disk is mounted/locked, but on linux it's forcing the removal if disk is mounted).

More than hundred hits but mostly regarding CPU and USB. Can you point 
me in the direction of the discussion you are referring to?
