List of oVirt/RHEV User Roles and its Permissions

Posted on 133 views

oVirt / Red Hat Virtualization environment has a variety of preconfigured roles. Users in the internal or external domain can
be assigned multiple roles at multiple levels in the oVirt/RHEV hierarchy. The roles listed in this article can be used to better manage user access and to delegate administrative authority in Virtualization environment. This enables you to limit access to [email protected] account while being able to properly track and manage users for compliance.

These roles that comes with the virtualization platform can be categorized in to two types of roles:

1. Administrative roles

Users with Administrative roles can access the Administration Portal and perform operations from there. By assigning less comprehensive roles to appropriate users, you’ll be able to offload administrative tasks.

SuperUser Role

  • A user assigned this role has full permissions across all objects and levels in your oVirt/RHEV environment
  • This role is assigned to [email protected] automatically
  • This role is fit for engineers with the responsibility of managing the Virtualization environment

ClusterAdmin

  • A user assigned this role will have administrative permissions for all resources in a specific cluster.
  • Fit for cluster administrators for specific clusters.
  • Users with this role assigned to one or more clusters are able to administer these clusters and their resources
  • User with this role can administer, but cannot create new clusters.

DataCenterAdmin

  • A user with this role has administrative permissions across all objects in a specific data center, except for storage
  • Meant for data center administrators for specific data centers
  • Users with this role cannot manage storage resources in data center, this is managed by a StorageAdmin.

PowerUserRole

  • A user assigned this role can create and manage virtual machines and templates at their assigned level, e.g within data center scope.
  • This role allows users to self-service their own virtual machines
  • A user will not be able to see virtual machines created by other users, unless at least UserRole is assigned on those machines

UserRole

  • With this role, a user can log in to the VM Portal – to see the virtual machine, start or stop that machine.
  • Users with this role cannot create new virtual machines, or edit or delete existing ones.

UserVmManager

  • Users with this role can manage virtual machines, create and use snapshots for the VMs they are assigned

  • A user is automatically assigned this role on a new virtual machine that user creates using the VM Portal

VmCreator

  • This role gives the user permission to create virtual machines using the User Portal.
  • Users assigned this role are able to create virtual machines from VM Portal

TemplateCreator

  • This role enables users to create, edit, manage, and remove templates

DiskOperator
