If you want to mount the domU LVM image, you can do the following : fdisk -l -u /dev/vg1/lv1 You will get something similar to this output : Disk /dev/vg1/lv1: 4294 MB, 4294967296 bytes 255 heads, 63 sectors/track, 522 cylinders, total 8388608 sectors Units = sectors of 1 * 512 = 512 bytes Device Boot Start End Blocks Id System /dev/vg1/lv1p1 63 899639 449788+ 82 Linux swap / Solaris /dev/vg1/lv1p2 * 899640 8385929 3743145 83 Linux So now, if you want to mount the second partition in the LVM, you must take the start number (899640) and multiply it by 512. This will give you the offset of the partition (460615680). After this, mount the partition with this command : mount -o loop,offset=460615680 /dev/vg1/lv1p2 /mnt -- Jean-François Saucier TC2L, http://tc2l.ca _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
