This host does not support 64 bit operating system (Vmware Esxi)

Hi guys

I have a Windows 7, 64bit OS. I've been inside of the BIOS and enabled Intel-VT and all Virtualisation capabilities that exist.

I have installed Vmware Workstation on my PC. In there, I loaded the Vmware Esxi 5 (pic 1).

Then I used the Vsphere client to access the hypervisor. And within there, I attempted to install a Windows 2008 Server from an ISO file (pic 2).

And it constantly comes up with an error (pic 3).

Any way I can get this working? I know that my cpu and motherboard support 64-bit and Vm hardware virtualisation.

Any ideas?

Thanks a lot
Yashy

the issue is not your motherboard and cpu, but you will need to enable Intel VT to pass through into the VM, when using nested Hypervisors.

see my blog you will need to make somevtweaks

Is your processor on the compatibility list?

but please note there are some motherboard and processors combinations, that DO NOT work, and have not been able to get to work, because of Intel VT passthrough to the VM.

Hanccocka - where do I go to change the 'add vhv.allow = "TRUE" to  /etc/vmware/config ?

Hanccocka, you won't believe it.

I uninstalled the Vmware Workstation 7 which I was running and installed Workstation 8.0 instead. Seeing as I had downloaded the Vmware Esxi 5, the Workstation 7 would only recognise up to 4.0. On 8, it has the option to recognise version Esxi 5.

The other thing that in 8.0 exists, is the ability to virtualise the engine (attached picture) and select the 'Intel VT' checkbox. I wonder whether all of this helped?

Also, I couldn't SSH to the machine. Firewall turned off and yet I couldn't SSH to it. So that's why I decided to uninstall it and attempt with the new workstation.

VMware Workstation 8.0 supports nested Hypervisors better.

Follow the above links, will give you the information which needs to be configured.

Use a single Processor, and reduce the ram to 4GB for test.

Access ESXi from the console to make the modifications.
