[Libguestfs] Virt-resize error (ntfs) : Fatal error: exception Guestfs.Error("ntfsresize_opts: /dev/vda2)

Hi. Libguestfs 1.14 Ubuntu 11.10 I am trying use virt-resize on NTFS partitions. I have installed Windows 2008 in an LVM partition (in order to use RAW) - I am trying to resize to a larger LVM partition. I have ntfsresize installed on the server - the windows partition is not encrypted. root@kvm1:~# ntfsresize -v ntfsresize v2011.4.12AR.4 (libntfs-3g) The attempt ends with an error Fatal error: exception Guestfs.Error("ntfsresize_opts: /dev/vda2) I have attached a txt file of the results where I have used export LIBGUESTFS_DEBUG=1 ; export LIBGUESTFS_TRACE=1 I have also tried using virt-resize --expand /dev/sda2 /dev/vgpool/w2008webtemplate /dev/vgpool/wintest2 as well as virt-resize --expand /dev/vda2 /dev/vgpool/w2008webtemplate /dev/vgpool/wintest2 Any ideas how to get it working ?
