[Libguestfs] Change partition type

Hi, Is there any way to change the partition type using python-guestfs? I'm trying to recreate an NTFS partition, but can not change the type to NTFS (7 identifier in frisk) Filesystem from my disk g.list_filesystems() {'/dev/sda1': 'ntfs', '/dev/sda2': 'ntfs’} Fdisk print g.sfdisk_l(device) Disk /dev/sda: 51200 cylinders, 64 heads, 32 sectors/track Units = cylinders of 1048576 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sda1 * 1 100 100 102400 7 HPFS/NTFS /dev/sda2 101 51199 51099 52325376 83 Linux /dev/sda3 0 - 0 0 0 Empty /dev/sda4 0 - 0 0 0 Empty Marcos Amorim
