Session host creation using a session host configuration
We extended the session host creation functionality from session host update and dynamic autoscaling to apply to all session hosts created in a host pool with a session host configuration. We also added support for Microsoft Entra-joined devices. This update brings the following changes:
• You can configure a host pool to use Microsoft Entra-join without needing to assign the Virtual Machine User RBAC role to a user.
• Error reporting is consistent across services and auto-retry functionality is added to session host creation to mitigate transient errors.
• Log analytics for a host pool now includes session host creation activity, providing a consolidated view of session host management. Resource group deployments no longer contain per-session host creation details.
• The host pool user interface, including banners, provides session host creation status on the session host menu item, though you should also enable log analytics on a host pool to see a detailed diagnostic history.
• You can now increase the host pool size via API or custom ARM templates, which triggers the Azure Virtual Desktop service to create new session hosts.
