[Libguestfs] [PATCH v2 00/13] virt-resize: add support for resizing MBR logical partitions

[Hu Tao]

The test script:

#!/bin/bash -
set -e

# test case 1: only primary partitions

guestfish -N disk <<EOF
part-init /dev/sda mbr
part-add /dev/sda p 64 255
part-add /dev/sda p 256 -128
EOF
virt-filesystems --all --long -h -a test1.img
truncate -s 1G test2.img
virt-resize --expand /dev/sda1 test1.img test2.img

if [ ! $? -eq 0 ]; then exit 1; fi

rm -rf test1.img test2.img

# test case 2: only logical partitions

guestfish -N disk <<EOF
part-init /dev/sda mbr
part-add /dev/sda extended 64 2048

EOF
virt-filesystems --all --long -h -a test1.img
truncate -s 1G test2.img
virt-resize --expand /dev/sda5 --resize /dev/sda6=+2000% test1.img test2.img

if [ ! $? -eq 0 ]; then exit 1; fi
