losetup /dev/loop0 image.img
kpartx -a /dev/loop0
mount /dev/mapper/loop0p1 /mnt/image
If kernel parameter (as loop in compiled into Fedora¡¯s kernel) like
loop.max_part=63
added it is even simplier:losetup /dev/loop0 image.img
mount /dev/loop0p1 /mnt/image
Alternative way is to specify direct offset to partition:
mount image.img /mnt/image -o loop,offset=32256
To mount qcow2 images there is (at least in F-11 qemu) very useful qemu-nbd util. It shares image through kernel network block device protocol and this allows to mount it:
modprobe nbd max_part=63
qemu-nbd -c /dev/nbd0 image.img
mount /dev/nbd0p1 /mnt/image
If LVM is present on image it could be initialized with:
vgscan
vgchange -ay
mount /dev/VolGroupName/LogVolName /mnt/image
Finishing is done with (depending on how it was initalized):
umount /mnt/image
vgchange -an VolGroupName
killall qemu-nbd
kpartx -d /dev/loop0
losetup -d /dev/loop0
