-
-* Reboot your XenServer into Grub boot menu.
-* Use arrows keys to locate an appropriate XenServer boot menu entry and press **e** key to edit boot options.
-* Locate read-only parameter **ro** and replace it with **rw**. Furthermore, locate keyword **splash** and replace it with **init=/bin/bash**.
-* **Hit F10** to boot into single-mode
-* Once in single-mode use **passwd** command to reset your XenServer's root password
-* Reboot xenserver by entering the command **exec /usr/sbin/init**
-* If everything went well you should now be able to login with your new XenServer password.
