Frame Guest Agent
Frame Guest Agent (FGA) is a collection of Frame-specific services that manage VM configuration and functionality. FGA provides the following services:
Communication between the VM and Frame backplane.
VM configuration, orchestration, and session management.
Session customization and scripting (stateful/stateless sessions, scripting, etc.)
Verification, migration, and upgrade orchestration.
Collection of server diagnostics and a variety of logs.
Frame Remoting Protocol (FRP) which is responsible for the capture, encoding, and streaming of virtual applications/desktops to end user devices.
FGA 8 supports both Frame Remoting Protocol (FRP) 7 (based on Secure WebSocket and TCP), and FRP 8 (based on WebRTC and UDP).
The required ports/protocols for Frame Guest Agent 8 (using FRP7 or FRP8) are documented in the Networking Requirements based on your Frame account's deployment model.
If your configuration relies on an OS-level firewall (e.g., Windows Firewall with Advanced Security or a third-party firewall) on a Sandbox, Utility Server, and/or persistent desktops, you will need to update firewall configurations on those workload VMs. For non-persistent Frame accounts, update the Windows Firewall on the Sandbox VM and publish, or use a GPO.
For example, using Windows Firewall with Advanced Security, Frame administrators would enable an inbound rule
UDP ports 4503-4509 (either via GPO or directly within the workload VMs) for FRP8.
- Go to Windows Firewall with Advanced Security
- Select “Inbound Rules”
- Right click > “New Rule…”
- Port > UDP > Specific local ports:
4503-4509> Allow the connection > Check all, Domain, Private, Public > Enter a name > Finish
Refer to the Networking Requirements for the complete list of inbound and outbound protocols/ports your OS firewall must allow for your workload VMs, specific to your deployment model, to work with your end users and Frame Platform using FRP7 and/or FRP8.
For non-persistent Frame accounts, Frame requires Windows updates to be applied in the Sandbox. Frame admins can then publish those updates to their test or production pools. During the provisioning of test or production workload VMs (triggered by a publish or the increase in the max Default Capacity), the Frame Guest Agent will disable Windows Update Services in the newly-provisioned non-persistent workload VMs.
Frame does not disable Windows Update Services in Sandbox, Utility server, or persistent desktop VMs.
App Mode 2.0
Administrators delivering Frame sessions via Application Launchpad can now provide an enhanced experience to end users with App Mode 2.0. App Mode 2.0 allows end users to access their onboarded applications from the Frame start menu within the session.
In legacy app mode, users are prompted to end their session if they close the application they selected from their Launchpad. With App Mode 2.0, users can now open multiple onboarded applications within the session and leave the session running without apps open (similar to a Desktop session).
Administrators can use App Mode 2.0 simply by enabling the toggle in the application Launchpad's settings.
Administrators can hide the Windows Task Bar with App Mode 2.0. Refer to Autohide the Windows Task Bar in App Mode 2.0 to understand how to use FGA Scripting to set the appropriate registry key to autohide the Windows Task Bar.
Frame Guest Agent logs can be found in the
C:\ProgramData\Nutanix\Frame directory within the session.
After filing a support ticket, you may be asked by Frame support personnel to provide these logs, if available.
