read LVM from windows

i want to recover old files from server to new disk

updates: this software not works. i'm using vmware player with centos and mount using this

To mount xen guest image (with lvm)

1. Check the partition on the image
# fdisk -lu /path/to/image

2. You have to install kpartx to handle lvm partiton
# yum install kpartx

3. Run kpartx on the image
# kpartx -av /path/to/image

4. Run vgscan to scan volume group available
# vgscan

5. Run vgchange to activate the volume group in the image
# vgchange -ay VolGroup00

6. Use lvs to see what is the name of your low volume group
# lvs

7. Mount the low volume group
# mount /dev/VolGroup00/LogVol01 /mnt

8. You can access your lvm image at the mounted directory which is /mnt

9. To unmount it, a few commands have to be executed (umount for unmounting, vgchange -an to deactivate volume group, kpartx -d to delete device map and losetup -d to delete loop device used)
# umount /mnt/
