What exactly is the problem here? 'change' is for floppy and CD, right?
The device stays realized/connected and guest-visible during that time,
and the guest should be able to live with no media while the new drive
is not yet decrypted. Are we just lacking a QMP command to enter the
password and complete the change while the guest is executing?
