Unable to Power on 64-bit VM’s on Nested ESXi Host

This post will be utilitarian for the vSphere Home lab. It is not then easy to buy multiple hardware for each ESXi servers running on your lab systems. You may need to run ESXi server as virtual machine on top of your physical ESXi host which is referred as “ Nested ESXi host ”. Have you tried to run 64 moment operating system on your nest ESXi host ?. If yes, then you may have come across the trouble oneself to power on 64-bit operating systems on top of your nest ESXi. Below error message will appear when you try to exponent on your 64-bit Guest OS virtual car on your Nested ESXi host ( virtual ESXi host ). The virtual machine requires hardware features that are unsupported or disabled on the prey host : ” ” ” ” ” ” ” * Longmode : required for 64-bit node OS defend. On Intel systems, longmode requires VT-x to be enabled in the BIOS. On nest virtual ESX hosts, longmode documentation normally requires upgrading your VM to ESX 5.1 compatibility level ( VM version 9 ) and enabling the “ Virtualized Hardware Virtualization ” flag on the outer VM. ” ” ” For incompatibilities other than NX/XD or longmode : if possible, use a bunch with Enhanced vMotion Compatibility ( EVC ) enabled ; see KB article 1003212.

ESXi 5.0

With ESXi 5.0, virtualized HV is prohibited by default. This have is used internally within VMware for testing purposes, but it is not recommended for production systems. It is available on hosts that support Intel VT-x or AMD-V, but it is not recommended for systems without irregular level address translation ( EPT or RVI ), because of its poor operation without SLAT. You must add the take after shape option to the /etc/vmware/config file on the physical master of ceremonies to run 64-bit Guest OS on your Nested ESXi host. vhv.allow = TRUE ESXi 5.1 & ESXI 5.5

With ESXi 5.1 and 5.5, Virtualized HV is fully supported for virtual hardware version 9 or 10 VMs on hosts that support Intel VT-x and EPT or AMD-V and RVI. you no need to add shape options to run your 64-bit node operating systems on your Nested ESXi host. You can follow the dim-witted steps mentioned below which will enable you to ability on your 64-bit virtual machines on top of your Nested ESXi. access your vCenter server using vSphere Web client, Power off your Nested ESXi host ( virtual ESXi host ). good cluck your virtual ESXi host ( Nested ESXi horde ) and Edit settings. see that VM compatibility is set as ESXi 5.5 and late. If it is not set, Upgrade your VM compatibility by good snap on VM – > All vCenter Actions – > Compatibility – > Upgrade VM Compatibility Edit your Nested ESXi Virtual Machine using vSphere Web customer – > Edit Settings– > Virtual Hardware – > Expand the CPU options. Select the option “ Expose the NX/XD flag to guest and select the checkbox “Expose hardware assisted virtualization to the guest OS” on Hardware virtualization choice. This choice will only be available in vSphere web node not on vSphere windows node. You can set the Guest OS version under – > VM options – > General options – > under Guest OS, Select early and Select VMware ESXi 5.x under Guest OS version. This is an optional step to track the Guest OS type. Click on Ok and exponent on your Nested ESXi ( Virtual ESXi car ).

With the above 3 simple steps, you will be able to power on 64-bit node operate on system on top your nest ESXi host. That ’ s it. I hope this is informative for you. Thanks for Reading ! ! !, Be Social and share it in social media, if you feel worth sharing it.
