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.

Note:
When the support from your OS vendor expires, Citrix might be limited in its ability to remediate problems. For deprecated or removed platforms, see Deprecation.
CentOS project shifts focus to CentOS Stream. CentOS Linux 8, as a rebuild of RHEL 8, ends at the end of 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux. For more information, see https://www.redhat.com/en/blog/centos-stream-building-innovative-future-enterprise-linux.
- At least one desktop must be installed. You can specify through the ctxinstall.sh or ctxsetup.sh script the GNOME, GNOME Classic, or MATE desktop environment to use in sessions.
- According to the Red Hat Enterprise Linux documentation, GNOME is the only desktop environment available in RHEL 9.

HDX 3D Pro
HDX 3D Pro of Citrix Virtual Apps and Desktops lets 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
- Amazon Web Services (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 15. For more information, see NVIDIA Virtual GPU Software Supported GPUs.
