Hi,

When support to resizing logical partitions is enabled, there is a
problem about resizing the extended partition: whether the extended
partition is automatically resized (expanded or shrunk) by virt-resize
based on the resizing of logical partitions?

All the cases can be categorized as these two:

1. user doesn't explictly resize the extended partition. In this case it
   seems reasonable to automatically expand the extended partition as well.

2. user explictly resizes the extended partition. If the extended
   partition is resized as user requested, then we should deal with the
   conflicts about resizing extended partition and logical partitions,
   this is somewhat tricky in the current implementation; But if the
   extended partition is automatically resized, user will be confused as
   the resulting size may be what he/she expects.

Ideas?

Regards,
Hu
