Read the files from a Xen virtual disk img

Yesterday I had to read the data from a Xen virtual disk img.
First I checked the partitions on the img file with:

#fdisk -l /storage/virtualMachines/templates/my.img

Second I run kpartx

#kpartx -a /storage/virtualMachines/templates/my.img


#ls -l /dev/mapper/
brwxr-xr-x 1 root root 253, 2 2010-06-29 22:16 loop0p1
brwxr-xr-x 1 root root 253, 3 2010-06-29 22:16 loop0p2

I mounted the first block device:

mount -o rw /dev/mapper/loop0p1 /mnt/

and found that it contains the /boot partition.
I umounted the first device, and mounted the second block device:

mount -o rw /dev/mapper/loop0p2 /mnt/

but I found that this is just a LVM2 volume.
I scan my system for LVM volumes and identify in the output the volume group name that has my Fedora volume:

vgscan

I activated my volume:

vgchange -ay vg_sender

Found the logical volume that has my Fedora root filesystem:

lvs

and mounted it:

mount /dev/vg_sender/lv_root /mnt/
