A note about this feature: we support live migration of redirected devices, but not of passthrough devices (which is kind of crazy... you would need a robot to re-attach the device to the destination machine and would run potentially run into al kind of racing problems).

I've added a requires_release_notes flag to the original bug.

Gerd's comment from Bug 840804
Hmm, there isn't much to document ...

In RHEL-6.3 it is impossible to live-migrate a virtual machine in case usb2 support has been enabled for it (by adding a virtual ehci controller).  In RHEL-6.4 this will work just fine.

No special action is needed to enable it.
