Re: [Xen-users] img file to physical disk

[Christian <chris@xxxxxxxxxxxxxxxx>]

Hi Bas,

i stuck a bit. This is what I tried.
tyan:/var/lib/xen # cd images/api/
tyan:/var/lib/xen/images/api # losetup /dev/loop0 disk0
tyan:/var/lib/xen/images/api # sfdisk -l /dev/loop0
Disk /dev/loop0: cannot get geometry

Disk /dev/loop0: 1305 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

  Device Boot Start     End   #cyls    #blocks   Id  System
/dev/loop0p1          0+     65      66-    530113+  82  Linux swap / 
Solaris
/dev/loop0p2         66    1304    1239    9952267+  83  Linux
/dev/loop0p3          0       -       0          0    0  Empty
/dev/loop0p4          0       -       0          0    0  Empty

now I stuck
what to do to mount "loop0p2". This is the partition I want to mount.
Thanks for your help

Kind regards
Chris
