[Xen-users] problems mounting HPFS/NTFS domU partition

[Studio Rivadossi <studio@xxxxxxxxxxxxx>]

Hello,

I'm not able to mount a HPFS/NTFS  domU partition.

My system:

dom0 is on a debian (Lenny) machine, using xen-hypervisor-3.2-1-i386 Xen 
Hypervisor.

domU is a Windows XP machine, that works well.
My target is to mount file system domU machine (when domU is not active).

In my domU configuration file I have:
disk = ['phy:/dev/virtual_machines/xp_disk,hda,w', 'phy:/dev/hda,hdc:cdrom,r']

My disk's partitions are:

fdisk -l
...
/dev/sda6            2678        6375    29704153+  8e  Linux LVM


pvscan
  /dev/cdrom: open failed: Read-only file system
  Attempt to close device '/dev/cdrom' which is not open.
  PV /dev/sda6   VG virtual_machines   lvm2 [28.32 GB / 5.32 GB free]

sfdisk -l -Us /dev/virtual_machines/xp_disk

Well, I would mount XP domU machine with "mount" command:

mount /dev/virtual_machines/xp_disk /mnt/lvm_disk/
mount: you must specify the filesystem type

If I use -t ntfs, I obtain:

mount -t ntfs /dev/virtual_machines/xp_disk /mnt/lvm_disk/
mount: wrong fs type, bad option, bad superblock 
on /dev/mapper/virtual_machines-xp_disk,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

tail /var/log/syslog

I think that I must use "mount" command with some options...
Can someone help me?

Thanks in advance,
