Nutanix VirtIO 1.1 Drivers Released

If you are a Nutanix customer and using AHV (Acropolis Hypervisor), I have some great news for you. We have released VirtIO 1.1 drivers, and the big deal is that they are now Microsoft WHQL signed. I know the lack of signing was holding back some customers for production workloads. No longer!

VirtIO 1.1And there’s a nice Nutanix install wizard:

Nutanix VirtIOPlease do note, this signed driver package is for 64-bit operating systems only. The supported operating systems are:

  • Windows 7
  • Windows 8.x
  • Windows 10
  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows Server 2016

You can directly download the drivers from here. We have them in both .MSI format and ISO, depending on your needs. All of the related documentation can be found here, including the special case of 32-bit operating systems. And don’t forget, if you want to inject the VirtIO drivers into your Windows ISO, check out my blog post here.

As of 5/1/2017, AOS 5.1 has not been enabled for automatic download and 1-click upgrades. As always, if you don’t want to wait for the automatic download switch to be flipped (in the near future), you can grab the AOS binary from the support portal and use our 1-click upgrade process. As always, thoroughly read the full release notes on the support portal before attempting an upgrade.
