Permissions available for each role Definitions of permissions Table 2. Definitions of permissions Page Page Working with RBAC using the xe CLI To list all the available defined roles in XenServer To display a list of current subjects: To add a subject to RBAC To assign an RBAC role to a created subject To change a subject's RBAC role: Auditing Audit log xe CLI commands To obtain all audit records from the pool To obtain audit records of the pool since a precise millisecond timestamp To obtain audit records of the pool since a precise minute timestamp How does XenServer compute the roles for the session?
