[Xen-users] [xcp] As for mounting the vm disk image file

[Fu Bin-zhang <fubinzhang@xxxxxxxxx>]

Hi all,

    I installed XCP and an VM (debian 6.0) on simics (a simulator). In simics, I have dumped the disk image file (xcp-vm.rebooted).
Now, i want to mount this file to my host machine. But, i get the error that "mount: you must specify the filesystem type".

    I find that fdisk reports "Partition 3 has different physical/logical beginnings (non-Linux?)". Is it the problem? And, what should i do to fix it?
   
    Any hint is appreciated. Thanks!

You must set cylinders.
You can do this from the extra functions menu.

Disk xcp-vm.rebooted: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders, total 0 sectors
