Citrix Systems 6 User Commands, VBD Commands, Update-upload, User-password-change, VBD Parameters

update-upload

update-uploadfile-name=<name_of_upload_file>

Streams a new software image to a OEM edition XenServer host. You must then restart the host for this to take effect.

User Commands

user-password-change

user-password-changeold=<old_password> new=<new_password>

Changes the password of the logged-in user. The old password field is not checked because you require supervisor privilege to make this call.

VBD Commands

Commands for working with VBDs (Virtual Block Devices).

A VBD is a software object that connects a VM to the VDI, which represents the contents of the virtual disk. The VBD has the attributes which tie the VDI to the VM (is it bootable, its read/write metrics, and so on), while the VDI has the information on the physical attributes of the virtual disk (which type of SR, whether the disk is shareable, whether the media is read/write or read only, and so on).

The VBD objects can be listed with the standard object listing command (xe vbd-list), and the parameters manipulated with the standard parameter commands. See the section called “Low-level Parameter Commands” for details.
