Get minimum size of NTFS filesystem in bytes. This is used primarily for shrinking images. In case of a full images ntfsresize returns error code and does not print minimum size. So we calculate it manually by rounding 'volume size' up to 'cluster size'. --- daemon/ntfs.c | 68 ++++++++++++++++++++++++++++++++++++++++++++++++++++ generator/actions.ml | 17 +++++++++++++

This action moves second(backup) GPT header to the end of the disk. It is usable in in-place image expanding, since free space after second GPT header is unusable. To use additional space, we have to move second header. This is what sgdisk -e does. However, sgdisk -e may perform additional actions if the partition table has unexpected params (e.g. if we call sgdisk -e /dev/sda1, it may fix

Some OSes (e.g. Windows Server 2012 R2) fail to boot after virt-resize due to changed disk guid. To fix it, we add new APIs: part_get_disk_guid part_set_disk_guid part_set_disk_guid_random We also preserve disk GUID in virt-resize. Maxim Perevedentsev (3): New API: part_get_disk_guid and part_set_disk_guid. New API: part_set_disk_guid_random. resize: preserve GPT disk GUID.
