Hello Experts,
I recently bought an intel-Core2duo-E7400 processor(VT-enabled) and a compatible mother board
with the VT enable/disable option in the BIOS.
When I try to install ESX-4 on work station 6.5 it gives the error as "This version of ESX requires a CPU capable of 64-bit operation."
The processor supports 64bit,EMT64t and VT-enabled. I have also set the option of Intel-v in the CPU setting of the VM.
Could you please suggest me what could be done to over come this? Your inputs are highly valuable.
Thanks
Vamsi
See .
According to Intel, the E7400 does not support VT.
E7400 supports VT.I have attached a screenshot of the e7400 with VT-x option.I have got the same chip.
You can find the same at this URL
I can also see the Intel-VT featured written on the processor box.
Could you suggest me the probable reasons for a CPU showing up the message "This version of ESX requires a CPU capable of 64-bit operation" ,even though it is VT enabled?
Check to see if your motherboard manufacturer has a later BIOS available for your motherboard.

Also, check to be sure that you're using Red Hat Linux 5 64bit as the client type when you building the VM for VMware Workstation.
Also, make sure you're using VMware Workstation 6.5.3 and have chosen Workstation 6.5 as the version type when building your VM.
If you're not already, use this document to build your ESX 4.0 VM under VMware Workstation:

Can you post a vmware.log file for your ESX VM?
This is a VMware Workstation question therefore I am moving the post to that sub forum.

What do you use for your Guest operating System? is it 64bit or 32 bit? (By guest I mean the OS that you are running your VMware WorkStation on it)
If you don't have 64 bit Guest OS, then you can not create a 64bit VM.
Let us know what guest OS are you using.
Thanks,
Hi Saadat - we usually use the terms guest and host the other way round. The guest is the OS inside the VM and the host is the OS that runs VMware.
And in this case the guest is ESX4 and this guest can run on 32bit and 64 bit hosts

Hi,
Continuum is right, Host Operating system is the OS that you have installed on your computer directly, and then you have installed VMware workstation on it.
and Guest OS is your virtual Machine that you want to use it as ESX 4 Server.
What I meant in my previous post was Host OS, But it seems (not sure) that Host OS is not important. As long as you have a supported 64bit CPU you should be able to create 32bit or 64bit Virtual Machines.
I never tested this myself because If I use a 32bit Host OS, I will limit myself to 4GB of RAM and that is not enough memory to run two or three ESX Servers in VMware Workstation.
According to VMware user guide
"Support for 64-Bit Guest Operating Systems
Workstation supports virtual machines with 64‐bit guest operating systems, running
on host machines with the following processors:
Revision D or later of AMD Athlon 64, Opteron, Turion 64, and Sempron
Intel Pentium 4 and Core 2 processors with EM64T and Intel Virtualization
Technology
Workstation supports virtual machines with 64‐bit guest operating systems only on
host machines that have one of the supported 64‐bit processors. When you power on a
virtual machine with a 64‐bit guest operating system, Workstation performs an internal
check. If the host CPU is not a supported 64‐bit processor, you cannot power on the
virtual machine.
VMware also provides a standalone utility that you can use without Workstation to
perform the same check and determine whether your CPU is supported for
Workstation virtual machines with 64‐bit guest operating systems. Download the 64‐bit
processor check utility from the downloads area of the VMware Web site.
Workstation supports virtual machines with 64‐bit guest operating systems only in
versions 5.5 and later. If your version of Workstation is 5.0 or earlier, upgrade to version
6.0 or later for 64‐bit guest operating system support. A virtual machine created in
Workstation version 5.5 with a 64‐bit operating system cannot be powered on or
resumed in Workstation versions 5.0 and earlier."
I am getting the error" This version of ESX requires a CPU capable of 64-bit operation", when I was trying to install ESX 4.0 in a VM of work station 6.5.2.
I strictly followed the document , which is meant for building ESX 4.0 VM under VMware Workstation.
I tried with the workstation installed on both win xp professional and also on win 2003 x64.
The following log is taken from vmware.log.
This host does not support VT. You have configured this virtual machine to use a 64-bit guest operating system. However, this host is not capable of running 64-bit virtual machines or this virtual machine has 64-bit support disabled. For more detailed information, see .
According to the URL ,my processor e7400 supports VT-x. I have enabled the VT option in the BIOS too.
Currently my BIOS is on version 65, Intel currently providing the latest BIOS (version-68) for my DG31PR mother board..Shall I go for a BIOS update?
But the version-68 doesn't have a fix for any of the VT related issues.
Only the following are fixed in version-68. Shall I go for a BIOS update still?
New Fixes/Features:
Changed post Logo file to correct resolution.
Added support to block BIOS update if using new LAN Chip.
New Fixes/Features:
Fixed issue where microcode does not get updated when flashing
BIOS version from 0053 to 0064.
Fixed issue where setting hard drive pre-delay has no affect on
boot time.
Fixed issue where wrong CPU temperature is displayed.
Please find the attached doc for more detailed information.
Please post the entire vmware.log file as an attachment.
Have you tried using Workstation 7, it is in beta but it supports ESX as a guest.

Have you tried using Workstation 7, it is in beta but it supports ESX as a guest.
The problem seems to be the board which does not support VT - changing to WS 7 will not change this

The problem is actually with the CPU. Either it really doesn't support VT (two out of three E7400 skus don't support VT), or it suffers from erratum AW67 (see Intel® Core™2 Duo Processor E8000 Series and E7000 Series Specification Update). A glance at the vmware.log file would help to decide which it is.
According to this post http://clintspot.blogspot.com/2009/01/vmware-cpu-vt-features-and-asus.html which has a similar problem with a different mainboard, I would recommend to upgrade the Bios.
See if that solves the problem.
Thanks,
Have you checked that (if it exists) "Trusted Execution" is disabled in the host BIOS?

The E7400 processor that I am having supports VT. The processors SPEC Code is "SLGW3".You can find the details of the processor in the below url.
My processor is mentioned in row two(BX80571E7400).
Please find the attached vmware.log file and kindly suggest me a solution for this.

I don't find any "Trusted Execution" option in the BIOS.But i can see a option called XD which is set to enabled.
