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.
