        You guys are running in circles.  The original poster said G4, then changed his description to G5 later.

         

        Get DLx80/x60 G5 with a processor that supports VT.  Then go into the host bios and enable it.

         

        Some very late model G4 would be able to run 64 bit oses as they're EM64T, but don't have VT technology, so 64-bit under ESX wouldn't happen.

         

        If you only have HT options with the latest bios you need to buy a different server.

          Hi All,

           

          Latest BIOS of my DL 380 G4 only support HT as an option and not VT. Also saw this is not a Xeon MP processor. So freed up a DL 580 G3 with single core Xeon MP 3GHz, 8MB L3 cahce (I thought this used to be codename Truland). This is for sure a 64 bit proc, if you at the specs at HP, DL 580 G3 does not even ship with a less proc then 64. OK, so I found the VT, turned it on, completely power cycled the machine (even removed the power supplies and drunk a cup of coffee). Then powered the system back up, but still cannot install a 64 bit guest OS =(

           

          What am I missing ? Should I reinstall ESX (makes no sense since code is directly put on the proc), is there another option, should I disabled HT when VT is on ?

           

          Any help appriciated.

           

          BR,

            Please download this ISO , burn to a CD, and boot from the CD.  It will verify that VT is enabled on each core of your host.

              Best is also to disable the HT

                Hi there,

                 

                I have also disabled HT now, ROMpaq flashed to the newest BIOS version of DL 580 G3 supported by VI3 (8-8-2006), power cycled (with iLO) and still no success.

                 

                Tomorrow monring I will drop by at my hosting centre to see if power cycle with full power off helps (alredy tried, but with older BIOS). I will also try mattsons iso cd.

                 

                I opened a case now at vmware and they said to run the vmware cpu compat tool (also a bootable cd). Last time it said 64bit longcode supported, 64 bit guest not supported. Sounds contradictionairy or not ?

                 

                I just enabled VT on my notebook (T7200 proc) and I could load 64 bits VMs right away with workstation. Why is this so difficult to solve, we have a machine, BIOS level, proc level and vmware level, not to many parameters I should say.

                 

                BR,

                  It's not contradictory.  Long-mode only requires EM64T.  64-bit guests on Intel hardware require both EM64T and VT.  VT is required because Intel does not provide segment truncation in 64-bit mode.  That means that without VT there is no way to protect the virtual machine monitor from the guest.

                   

                  I think you are going to find that your BIOS does not enable VT, or that it does not enable VT for each core.

                    Hi Mattson,

                     

                    I run the vt.iso and I see the following :

                     

                    CPU 0 This core does not support VT

                    CPU 1 This core does not support VT

                     

                    I have enabled VT in the BIOS of the machine ... ? What does this mean ? That the option is there in the BIOS but is of no use, since my procs do not support it ? Or that I did not power cycle enough (should have unplugged for a little longer then 30 seconds).

                     

                    And if these procs do not support VT, I have to buy others. Do you know what procs for sure will work in my machine ?

                     

                    Any ideas ?

                     

                    BR,

                      It means that these processors do not support VT at all, no matter what options you set in the BIOS.

                       

                      And if these procs do not support VT, I have to buy

                      others. Do you know what procs for sure will work in

                      my machine ?

                       

                      I don't know what processors would work in your system. I would suggest that you contact your HP representative.  I'm sorry that I can't be of more help.

                        Hey guys,

                         

                        I want to be able to check through the command line if VT is enabled in the BIOS for scripting purposes. I know we can check if VT is supported by the chip using the following:

                         

                        http://www.howtogeek.com/howto.....pports-vt/

                         

                        But is there any way to check if its enabled in the BIOS? Perhaps there is a small test to run that uses VT that can fail if its not enabled in the BIOS?

                          Is this DL380 G4 incompatibility with the CPU only or the CPU and Mainboard? I'm trying to determine if purchasing new Processors only for my G4's will get me up to spec here?
