 - You must grant Azure Virtual Desktop access to power on session host VMs, check their status, and report diagnostic information. You must have the `Microsoft.Authorization/roleAssignments/write` permission on your subscriptions in order to assign the role-based access control (RBAC) role for the Azure Virtual Desktop service principal on those subscriptions. This is part of **User Access Administrator** and **Owner** built in roles.

 - If you enable Start VM on Connect on a host pool, you must make sure that the host pool name, the names of the session hosts in that host pool, and the resource group name don't have non-ANSI characters. If their names contain non-ANSI characters, then Start VM on Connect won't work as expected.
