Hi, have you installed NGT?  This should include the latest supported drivers.

You mean Nutanix Move?  Move will attempt to inject drivers if you give it the right permissions but they may not be up-to-date.  I would definitely recommend you install NGT (Nutanix Guest Tools) on the guest VM through Prism.

Hi,

This is indeed strange issue here, i will advise to open ticket with Redhat / Nutanix. There was a known issues with lshw package, updating that might help.
