Nutanix AHV Appliance Quick Start

Beta

Nutanix AHV support is currently in beta. The QCOW2 appliance image is built from the same AlmaLinux 9 base and provisioning scripts as the VMware OVA. Please contact support if you encounter any issues.

Every new release automatically builds a QCOW2 disk image based on AlmaLinux 9. All security updates are applied during the build, and you can update packages as needed using standard Red Hat tools like dnf update.
