xen reset guest root password

I need to reset a root password on a Debian xen guest domain. Is there a way to do this without remounting the domain and chrooting into it? If not, is there someone who can give an example of how to do that?

 

I don't think so.

Like this:

Code:

mount -o loop /vserver/images/vm01.img /vserver/vm_base
chroot /vserver/vm_base

passwd root

exit
umount /vserver/vm_base

 

thanks a lot falko, this saved a lot of time and allowed far fewer angry e-mail users on domU

 

I tried to boot like this but got error message:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,

am i doing anything wrong?

thanks for any help

 

Run

Code:

modprobe loop

and try again.

 

This gives an error: "you must specify the filesystem type". My file system is Linux LVM.

Hi falko and cameron, I found the following on Skipfast blogspot which worked for me (Debian & LVM)

Recover XEN Guest Root Password

Have you come across a situation when you need to reset the root password of a XEN virtual box.

Logon Host machine run following command to boot guest OS in single usermode and simply recover root user password as normally we do.

#xm create -c /etc/xen/guest_vm_name extra=1

Cheers!
