- Cross Hypervisor migration – Nutanix NGT tool offer to convert the virtual disk from qcow2 to vmdk or vmdk to qcow2. If you are using two different hypervisors like VMware vSphere ESXi at DC and Nutanix AHV at DR site. When you replicate the VMs from to or from DC to DR then virtual disk will be converted in hypervisor supported virtual disk format.
- In-Place Hypervisor Conversion – Nutanix NGT tool provide in-place hypervisor conversion from VMware vSphere ESXi to Nutanix AHV and vise-versa after installing the Nutanix NGT tool in guest VM ( Windows / Linux )
Note1: Windows VMs, uninstalling the NGT software inside a VM does not uninstall the Nutanix virtIO package. This ensures that the VM always have the required drivers for mobility purpose.
For example, the VM might be migrated from one hypervisor to another ( Cross Hypervisor Migration To-from Nutanix AHV )and if drivers are uninstalled, the VM might not be able to start properly.
Note2: Uninstalling Nutanix VM Mobility drivers removes SCSI virtIO drivers leading to VM boot failures.
Nutanix NGT Tool Security Features
Nutanix NGT tool offer the three layer of security feature for VM communication. the communication will be considered successful only if all the three conditions are met as shown below.
Nutanix NGT tool offer the three layer of security feature:
- SSL certificates
- Capability based authorization
- System / BIOS UUID of the VM should be same as seen by the hypervisor – Nutanix AHV – Boot VM in BIOS UEFI Mode
Example, if a guest VM that has Nutanix NGT installed is cloned, then the new guest VM will not be able to communicate with the Controller VM.
