Clarify that the number of extents provided in BlockdevCreateOptionsVmdk must match the number of extents that will actually be used. Providing more extents will result in an error now. This requires adapting the test case to provide the right number of extents. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
