This implements support for MBR logical partitions in nbdkit-partition-filter, complementing existing support in the partitioning plugin. Rich.

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). Regards, Hu 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...

An evolution of the patch I posted yesterday to qemu-devel (https://www.mail-archive.com/qemu-devel@nongnu.org/msg588920.html) which (a) works and (b) has a test. Rich.

I think this addresses everything in Eric's v2 review. Note that the first patch is best viewed using ‘-w’ to ignore whitespaces changes. Rich.

For MBR, logical partitions laid inside extended partition. Add 3 variables to describe this: - partitions flat list of primary partitions (as now, the global 'partitions'). extended partitions is essentially primary partition - logical_partitions flat list of logical partitions - extended_partition one...

Hi Rich, This is v3 series to add support for resizing MBR logical partitions. changes to v2: 1. remove p_part_num 2. remove filter_parts 3. name the function calculate_target_partitions 4. remove the code to restart guest introduced in v2 changes to v1: 1. spit the patches so it's easier to review 2. fix the parted error caused by unaligned logical partit...

Hi, if I inspect an hybrid ISO with tools like fdisk and gdisk, then looks like hybrid ISO has both the MBR and GPT in order to support both the BIOS and UEFI: # gdisk -l /dev/sdb GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: present Found valid MBR and GPT. Which do you want to use? 1 - MBR 2 - GPT 3 - Create
