Download Latest Nutanix Virtio Driver For Windows OS

Download Nutanix latest virtio drivers for Windows OS 32 bit / 64 bit operating systems – Windows OS 32 bit / 64 bit 7, 8, 8.1, 10 and 11 Windows Server 2008R2, 2012, 2012R2, 2016 and 2019, 2022 and 2025 Nutanix Acropolis Hypervisor (AHV) support virtio driver for Microsoft Windows operating system to install basic core drivers.

Virtual machines running on Nutanix AHV require proper drivers to communicate efficiently with the underlying hypervisor. One of the most important drivers in this context is the Nutanix VirtIO Driver.
Without this driver, Windows virtual machines may run, but performance, stability, and functionality will be limited.

This section explains what the Nutanix VirtIO driver is, why it is required for Windows operating systems, and what advantages it provides in real-world environments.

What Is Nutanix VirtIO Driver

The Nutanix VirtIO Driver is a set of optimized paravirtualized drivers designed to improve communication between a Windows virtual machine and the Nutanix AHV hypervisor.

Nutanix Virtio Driver is basic required driver package for Microsoft Windows operating system which is installed during Windows OS installation on Nutanix AHV Hypervisor only.

In simple terms, it acts as a bridge that allows the guest operating system to interact directly and efficiently with virtual hardware such as:

• Data bus service – SCSI driver
• Network driver
• Memory Ballooning driver
• VM Mobility drive

Instead of using generic emulated hardware drivers, VirtIO drivers allow Windows to understand that it is running inside a virtual environment and to use optimized interfaces provided by the hypervisor.

What Is the Use of Nutanix VirtIO Driver in Windows OS

Windows operating systems do not natively include AHV-optimized drivers. During Windows installation on AHV, the installer may not detect storage or network devices unless VirtIO drivers are provided.

The Nutanix VirtIO driver is used in Windows virtual machines for the following key purposes:

1. Storage Device Recognition During Installation

When installing Windows on AHV, the installer often cannot see the virtual disk without VirtIO storage drivers.

VirtIO drivers allow:

• Detection of virtual disks
• Faster disk input and output
• Stable disk communication with AHV

Without these drivers, Windows installation may fail or require fallback to slower emulated devices.

2. High-Performance Network Connectivity

VirtIO network drivers replace slow, emulated network adapters with optimized virtual NICs.

This enables:

• Higher network throughput
• Lower latency
• Better packet handling
• Improved application performance

This is especially important for database servers, application servers, and web workloads.

3. Optimized Disk and I/O Performance

VirtIO storage drivers significantly reduce overhead between the VM and hypervisor.

Benefits include:

• Faster read and write operations
• Reduced CPU usage
• Improved response time
• Better scalability under load

This directly impacts overall VM performance.

4. Stable Windows VM Operations on AHV

VirtIO drivers ensure proper communication between Windows and AHV, reducing issues such as:

• Disk timeouts
• Network drops
• Driver-related crashes
• Performance bottlenecks

They are essential for production-grade Windows workloads.

5. Required for Advanced AHV Features

Some Nutanix AHV features work best or only when VirtIO drivers are installed, such as:

• Live migration
• Snapshot operations
• Storage optimization
• Consistent VM performance

Nutanix Virto Driver Version History

Nutanix VirtIO drivers are released and maintained alongside Nutanix AHV and AOS software updates. These drivers enable Windows virtual machines to communicate efficiently with the AHV hypervisor. Over time, Nutanix has improved performance, stability, and Windows OS compatibility through multiple VirtIO driver releases.

Below is a practical reference table that outlines commonly used Nutanix VirtIO driver versions, their approximate release timeframe, and supported Windows operating systems.
