Hi Rich, This is v5 series to add support for resizing MBR logical partitions. please review. Thanks! changes to v4: 1. add support to resize extended partition (--resize or --expand extended partition) 2. fix the problem of deficit of 512 bytes when expanding a logical partition (this problem can be reproduced in v4 by only expanding a logical partition, without resizing any other

Hi Rich, This is rebase of v5 series. Meanwhile, I found a bug when shrinking partitions, and the fix is incuded in this version (patch 2).

In current virt-resize, only primary partitions(including extended partition) are supported. They are collected in an array for resize operations. Logical partitions are not supported. This series add support for resizing logical partitions. v2: 1) Add 3 variables to describe relationship of logical and extended partitions: - partitions flat list of primary partitions (as now, the global

Some simple refactoring of virt-resize. I originally had the idea that we could turn virt-resize into a library (cf. virt-customize) and use it from virt-builder, but I now don't think that would make any meaningful difference. In particular we'd still have to open the handle the same number of times. These two patches are left over from my work on that. Rich.

Hi Rich, This is v3 series to add support for resizing MBR logical partitions. changes to v3: 1. merge patch 1 and patch 3 in v3 2. let mbr_part_type return 'primary' for GPT partitions 3. add test for resizing logical partitions 4. fix extending the extended partition (yet). see patch 7. changes to v2: 1. remove p_part_num 2. remove filter_parts 3. name the function
