How to Install Nested Esxi as VM on Esxi Server.
First…. download the Esxi Hypervisor and upload it on the datastore of your physical Esxi Server.
Then start creating a VM as per below procedure.
My way of creating a VM is just to go to the host of my choice and click Actions > New virtual Machine…
Select a creation type
I’ll call it esxi-nestvm and place it to the folder vSphere6.0 and select a host and a datastore with sufficient resources
The Compatibility with ESXi 5.5 and later is fine in my case, but you need to think about your migration possibilities and how they get limited. That’s the same as selecting the latest version of virtual hardware (10) on this installation as it is running on vSphere 5.5.
Since there is no Guest-OS nested vSphere 6, the guest-os type is other 64-bit with the Guest OS Name ESXi 6.0.
The configuration is pretty straightforward:
- 2 vCPUs (2 CPU is the minimum requirement)
- 6GB of memory (4 GB is minimum, 8 GB and more is recommended for productive infrastructures)
- 15GB of disk-space as a single hard disk
- vmxnet 3 for the network adapter type
If the summary screen shows all the correct settings hit Finish to deploy the VM and start the advanced settings.
Advanced settings of the VM
After creating the empty VM I have to change some advanced settings to to have ESXi 6.0 running smoothly.
CPU Hardware virtualization should be set to “Expose hardware assisted virtualization to the guest OS” to have full virtualization support on the CPU enabled.
And second to make sure to enable the Failed Boot Recovery option. Using this option the VM reboots frequently when no boot device is found. So it’s looping reboots till the .iso is attached to the system. This is only necessary for the installation process and can be unchecked when the installation is complete.
Installation of ESXi within the VM
You are ready now to install ESXi Hosts nested.
Boot the esx_nestvm and open the console to continue the standard esxi installation steps.
