CentOS - Sep 2009 - mounting images created using dd that contain two partitions

Hi all,

I am trying to mount images that I previously created with dd and the
images have two partitions (swap and LVM). I use these images to house
data for my Xen Guests.

For some reason (possibly Kernel conflicts for paravirtualized
domains) I am unable to boot my Guest images. Failing which I would
like to mount the disk images and atleast get my data out of them.

dd -o loop server.img /media/diskimage

asks me to provide a file system. How can I mount these images?

I have been Googling around for this and have failed to find and
answer, can someone please point me in the right direction.

Appreciate your time.

You'll probably need at least kpartx to mount the partitions out of the
image.  Maybe even the LVM tools, if you've created some of the
filesystems inside the image as LVs.

Perhaps the page at the following may give you some inspiration:

Is your local host using LVMs and if so, is your volume group  
something like VolGroup00?

Is your image file also of a VolGroup00?
