Thanks a lot!

I did so; It could be that there is a slight error in that wiki page, or that
something in my configuration is a bit different.
I tried to mount an image which was installed on a regular file.
It was slightly different than the wiki; any case I did manage
to solve it ; down below is what problem I had and how it was solved,
so that others may benefit from it (and maybe the wiki should be changed, I really do
not know).
The "Accessing guest disk image" says:
"Note that this only works for block devices, not for images installed on regular
files. To use file images, you'll need to set up a loopback device for the file
first:
# losetup -f
/dev/loop0
# losetup /dev/loop0 /xen/images/MyImagefile.img
# kpartx -av /dev/loop0
add map loop0p1 : 0 208782 linear /dev/loop0 63
add map loop0p2 : 0 12370050 linear /dev/loop0 208845
In this case we have added an image formatted as a default Fedora install,
so it has two partitions: one /boot, and one LVM volume
containing everything else. They are accessible under /dev/mapper:
# ls -l /dev/mapper/ | grep guest1"
***In my case***, ls -l /dev/mapper/ does ***NOT*** contain guest1;
ls -l /dev/mapper/ shows:
crw------- 1 root root 10, 62 Mar 17 11:43 control
brw-rw---- 1 root disk 253, 0 Mar 17 13:22 loop0p1
brw-rw---- 1 root disk 253, 1 Mar 17 13:22 loop0p2
But continuing with
mount /dev/mapper/loop0p1 /mnt/boot/
instead:
mount /dev/mapper/guest1p1 /mnt/boot/ (as in the Wiki)
did the job.
The same is for kpartx:
kpartx -a /dev/mapper/loop0p2
and then :vgscan
**instead of:**
kpartx -a /dev/xen/guest1
and then :vgscan
(as in the wiki)
did the job.

Hello,
I had created an image file with virt-install under Fedora 6 with
something like:
virt-install -n guset2 -r 256 -s 4 -f /var/lib/xen/images/guest2/guest2File -l ftp://mirrors.hpcf.upr.edu/pub/Mirrors/redhat/download.fedora.redhat.com/6/i386/os -p --nographics
Is there a way to mount Read-Write or Read-Only this file
(/var/lib/xen/images/guest2/guest2File) from within dom0 ?
