I keep getting an error message when trying to setup ESXi 5 on VMware workstation. The ESXi installer boots up and there is a progress bar at the top. When this bar 'fills up' the installer wants to start the kernel but it freezes and VMware workstation displays the error message: "The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point."
Yes you can do this. This have been done and tested.
You just need a 64-bit CPU and also VT-x supported.
After this, you can install VMware Workstation 8 and then create a vSphere 5 inside.
Take a look at this article, where you can do this, and what changes you need to do in your VMware Workstation or VM that will hold that ESXi.
Hope this can help you
Do it for your tests.
That is a really intersting question. Teorically you cannot do this, you cannot install VMWare EsXI or Hyper-V in a Virtual Machine. This is because they are hypervisor, bare metal sofware, that means, virtualization software that runs directly on the hardward without a host OS, as you can imagine it has lots of performance advantages.
However looks like in VMWare are really genius working and now you can do it, Since VMWare Worksation 8. (in earlies versions is not possible).
This is called Nested VMS. An impressive thing is even if your host computer dont support hardware assisted virtualization can run hypervisor on a Virtual Machine.
There is available this documment at the VMware Website that speaks about it and how to use it: Running Nested VMs.
Particulary for casa of running EsXI you will see details at the document, but for start and run the virtual Machine you will need to change the virtual machine processor settings and enable the checkbox "Intel VT-x/EPT or AMD-V/RVI."
