Enable VT-d and IOMMU. For more information, refer to steps one and two in
`Create Virtual Functions`_.
For Hyper-V compute nodes, the requirements are as follows:
* Windows 10 or Windows / Hyper-V Server 2016 or newer.
* VT-d and SR-IOV enabled on the host.
* Assignable PCI devices.
In order to check the requirements above and if there are any assignable PCI
devices, run the following Powershell commands:
.. code-block:: console

If the compute node passes all the requirements, the desired assignable PCI
devices to be disabled and unmounted from the host, in order to be assignable
by Hyper-V. The following can be read for more details: `Hyper-V PCI passthrough`_.
