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

Onestly I don’t know; I have migrate VM from VMWare to AHV using Nutanix appliance 

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.  

Hello @bxxst 

Please follow the below link for how to install NGT on a Linux VM:

Hi,

The strange fing is that encrease the RAM, OS see more ram but never the one set on VM configuration

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.
