Yes, at the driver level, there are some things that are unimplemented, as you
say. Some of those changes would be very scary (like changing params
underneath a device that''s in use) so will probably stay unimplemented,
unless
you have a very good reason to need to do that. xm block-configure is most
useful for changing the "disk" inside a CD-ROM drive that''s
being emulated by
QEMU.
