Linux Virtual Delivery Agent

What’s new

What’s new in 2603

New .NET version required

Starting with this release, you must install .NET Runtime 10 on all supported Linux distributions before you install the Linux VDA.

If your Linux distribution contains the .NET version that you require, install it from the built-in feed. Otherwise, install .NET from the Microsoft package feed.

New hypervisor and cloud platform support

Linux VDA operation has been validated on OpenShift Virtualization, Amazon WorkSpaces Core, and Nutanix Prism Central, expanding support for modern infrastructure deployments.

MCS-based deployments are supported on Amazon WorkSpaces Core and Nutanix Prism Central. OpenShift Virtualization supports Linux VDA operation but does not support MCS deployment.

Support for light weight database option

Since release 2603, Linux VDA supports built-in registry (light weight database) service for configurations instead of using database like PostgreSQL or SQLite. To use built-in registry service, set “DbType“ to “ctxregd“ in /etc/xdl/db.conf after installing. By default, for newly installed Linux VDA, DbType is set to ctxregd. For upgraded Linux VDA, the db.conf should use the old one and DbType will not be overwritten.

Clipboard file size control support

Added file size enforcement to clipboard size control policies to enhance clipboard security.

When Limit clipboard client to session transfer size or Limit clipboard session to client transfer size policy is enabled, below configured file size(in kB) limits are enforced.

Linux VDA GUI‑based setup tool available

Added a new GUI‑based Linux VDA setup tool to simplify provisioning workflows and reduce manual configuration errors.

Adapted to MCS prepared image workflow

Linux VDAs now support the MCS prepared image workflow, enabling reuse of pre‑generated images across catalogs to lower storage costs and streamline image management and updates.

Adcli‑based machine password management in the MCS workflow

Linux VDAs provisioned with MCS now use adcli for machine account password rotation, replacing Samba to enhance security compliance and minimize administrative overhead.

Support for Audio volume synchronization

Starting from release 2603, Linux VDA now supports synchronization of audio volume between the VDA and your audio devices. You can now adjust the volume using the VDA audio volume slider and have the same volume on your device and this also applies to the other way around. This feature is enabled by default.
