Definitions of permissions

This section provides additional details about permissions:

  • Add and remove users
  • Add and remove roles from users
  • Enable and disable Active Directory integration (being joined to the domain)

This permission lets the user grant himself or herself any permission or perform any task.

Warning: This role lets the user disable the Active Directory integration and all subjects added from Active Directory.

Log in to server consoles

  • Server console access through ssh
  • Server console access through XenCenter

Warning: With access to a root shell, the assignee could arbitrarily reconfigure the entire system, including RBAC.

Server backup/restore

  • Back up and restore servers
  • Back up and restore pool metadata

The ability to restore a backup lets the assignee revert RBAC configuration changes.

  • Import OVF and OVA packages
  • Import disk images
  • Export VMs as OVF/OVA packages

Set cores-per-socket

  • Set the number of cores per socket for the VM’s virtual CPUs

This permission enables the user to specify the topology for the VM’s virtual CPUs.

Convert VMs using XenServer Conversion Manager

  • Convert VMware VMs to XenServer VMs

This permission lets the user convert workloads from VMware to XenServer by copying batches of VMware VMs to XenServer environment.

Switch-port locking

  • Control traffic on a network

This permission lets the user to block all traffic on a network by default, or define specific IP addresses from which a VM is allowed to send traffic.

Log out active user connections

  • Ability to disconnect logged in users
