Nutanix Hyper HCI developed it’s own KVM based hypervisor known as Acropolis Hypervisor (AHV) which enterprise cloud ready platform to build Hyper HCI infrastructure to run any type of applications in production.

To change the Nutanix Acrpolis Hypervisor AHV host name is very important to make entry in Domain Name Server (DNS) for name resolution.

Lets proceed to do hands on changing Nutanix AHV host name will have to run simple command and do edit two scripts to change the Nutanix AHV hostname.

Step 2 : check current Nutanix AHV host name first

ahv@root# hostname

Run Acropolis command to avoid AHV host reboot
