Automatically re-image used hosts on log-off

Applies to: Nerdio Manager for MSP (NMM) v2.0.1+

The "auto re-image used hosts on log off" feature ensures that users always log into a pristine, image-based session host by refreshing (re-imaging) used host VMs after users log off. You can enable this setting while configuring autoscale settings on your dynamic host pool.

Let us explore how you can configure "auto reimaging of used host VMs" feature.

Login to NMM portal and click "Manage" option on an existing account:


From the main menu on your account's page, select "AVD->Host pools" tab as shown below:


Select a host pool say "Nayan-Test" and expand "Manage Hosts" drop-down on it:


Select "Manage Hosts->Auto-scale->Configure" option to configure auto-scale settings on your dynamic host pool:



You need to enable the auto-scale toggle switch (located on the right hand side of the screen) for your dynamic host pool and choose appropriate settings for Host pool sizing, Scaling logic, Pre-stage hosts and Messaging sections as shown below:


Refer this article to understand how to configure autoscale settings on your host pool.

Enable "Automatically re-image used hosts" flag under the "Manage auto-scale" section of your dynamic host pool. Enabling this flag makes sure that users logged onto the selected host pool always have access to a refreshed, image-based session host. Once the last user logs off, the session host will be re-imaged based on the "Desktop image (template)" specified on the host pool which is "Windows 10 (1909) EVD (multi-session)" in this case. This feature is available for both single-user host pools and multi-user host pools. In single-user pooled scenarios, desktops will be automatically re-imaged when users log off.  In multi-user pooled scenarios, session hosts will be re-imaged as soon as the last user logs off.  This way, all hosts will be always kept up-to-date and in a pristine state.
