Basic high level question re updating drivers in IaaS VM

Microsoft support asked me to update my NIC driver to resolve an issue we have been having.
I'm running a Windows IaaS VM in Azure.
I was under the impression that manually updating drivers via device manager would not be necessary due to virtualisation layer.
Am I mistaken? Are driver updates still required when running IaaS VM's?

Hi,

I don't see why the virtual machine drivers would need to be updated, it is the underlying hardware that requires updating drivers & firmware.
Unless you are running GPU driven VMs, then those will require driver updates for the GPUs.


Best regards,
Leon

Yes - this is also what I thought.
To elaborate slightly - this is the nic for accelerated networking. The Mellanox ConnectX-3 Virtual Function Ethernet Adapter.
I have been asked to update the driver for this. I should not attempt?

Ah I see, if it's an accelerated Networking Azure VM, in this case you might indeed need to update the drivers.

Hi,

As Leon mentioned, you can only attempt to Nvidia GPU drivers to leverage GPU capabilities

Along with that, you will be able to update accelerated networking
