System requirements
The Current Release of the Linux VDA is aligned with Citrix Virtual Apps and Desktops. It is also backward compatible with earlier versions of Citrix Virtual Apps and Desktops that haven’t yet reached the end of their lifecycle. For information about the Citrix product lifecycle, and to find out when Citrix stops supporting specific versions of products, see the Citrix Product Lifecycle Matrix.
The configuration process for Linux VDAs differs slightly from Windows VDAs. Any Delivery Controller farm is able to broker both Windows and Linux desktops.
System requirements for components not covered here (such as Citrix Workspace app) are described in their respective documentation sets.
For information about using a Current Release (CR) in a Long Term Service (LTSR) environment and other FAQs, see Knowledge Center article.

Supported host platforms and virtualization environments
- Bare metal servers
- Citrix Hypervisor
- VMware vSphere Hypervisor
- Microsoft Hyper-V
- Nutanix AHV
- Microsoft Azure
- Amazon Web Services (AWS)
- Google Cloud Platform (GCP)
Note:
In all cases, the supported processor architecture is x86-64.
Starting with the 2203 release, you can host the Linux VDA on Microsoft Azure, AWS, and GCP for Citrix Virtual Apps and Desktops and Citrix DaaS (formerly Citrix Virtual Apps and Desktops service). To add these public cloud host connections to your Citrix Virtual Apps and Desktops deployment, you need Citrix Universal Subscription or Hybrid Rights licenses. For information about Universal Subscription and Hybrid Rights licenses, see Transition and Trade Up (TTU) with Citrix Universal Subscription.

HDX 3D Pro
The HDX 3D Pro capabilities of Citrix Virtual Apps and Desktops let you deliver desktops and applications that perform best using a Graphics Processing Unit (GPU) for hardware acceleration.
Hypervisors
For the Linux VDA, HDX 3D Pro is compatible with the following hypervisors:
- Citrix Hypervisor
- VMware vSphere Hypervisor
- Nutanix AHV
- Microsoft Azure
- AWS
- Google Cloud Platform (GCP)
Note:
The hypervisors are compatible with certain Linux distributions. To use HDX 3D Pro for Amazon Linux 2, we recommend you install NVIDIA driver 470.
GPUs
To learn which NVIDIA GPU cards your Linux distribution supports, go to the NVIDIA product support matrix and check the Hypervisor or Bare-Metal OS, Software Product Deployment, Hardware Supported, and Guest OS Support columns.
Ensure that you install the latest vGPU driver for your GPU card. Currently, the Linux VDA supports up to vGPU 14. For more information, see NVIDIA Virtual GPU Software Supported GPUs.
