If your CPU only supports Intel-VT or AMD-V, then you can still install nested ESXi, but you will only be able to run nested 32-bit VMs and not nested 64-bit VMs. Note: If this box is grayed out, it means that your physical CPU does not supported Intel VT-x + EPT or AMD-V + RVI which is required to run VHV OR that you are not using Virtual Hardware 9. Step 3 – During the customize hardware wizard, expand the “CPU” section and select “Hardware Virtualization” box to enable VHV. Step-2: Select “Linux” as the guestOS Family and “Other Linux (64-bit)” as the guestOS Version. Select the Resources ( Datacenter and Host) Step-1: Create a new Virtual Machine using the new vSphere Web Client that’s available with vCenter Server 5.1 To Enable VHV (Virtual Hardware-Assisted Virtualization) for ESX You can now enable VHV on a per VM basis and using the new vSphere Web Client which basically adds the vhv.enable = “true” parameter to the VM’s. This also allows for better portability between VMware’s hosted products such as VMware Fusion and Workstation as they also support the vhv.enable parameter. In the earlier versions we used to set vhv.allow = “true”, this is no longer is use from the ESX 5.1 to enable VHV, new parameter has been introduced in the recent version called vhv.enable = “true” now that has to set for all the VMs to provide finer granularity of VHV support. Nested Virtualization with the 5.1 Release Intel VT-x or AMD-V is required for running “Nested Virtualization” which supports nested 32-bit VMs, Intel EPT or AMD RVI is required for running nested 64-bit VMs.Ī quick way to verify whether your CPU truly supports Intel-VT+EPT or AMD-V+RVI, you can paste the following into a browser: You will need to login with your root credentials and then look for the “nestedHVSupported” property and if it states false, it means you may be able to install nested ESXi or other hypervisor, but you will not be able to run nested 64-bit VMs, only 32-bit VMs, assuming you have either Intel-VT or AMD-V support on your CPUs. Nested ESX / Virtualization is the ESX or any hypervisor running as a pseudo-machine, in this blog we will see how to set up ESXi 5.1 as a VM in ESXi 5.1 and Installing ESXi 5.1
