Hi,
got some strange problems installing Windows 2008 64bit on out ESXi-Server. the Host machine is 64 bit, Hyperthreading enabled, if i try to install Windows 2008 directly the 64 bit versions is installed correctly. if i install ESXi on the same machine and try to install a new virtual machine with windows 2008 64 bit the installation stops with 0xc00035a Error saying
Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.
strange ?!?
is it neccessary to use some special settings for the virtual machine ?
hope anybody can help me
Hi,
In order to use 64 bits windows virtual machines on vmware esx server the cpu needs to have virtualization technology enabled in BIOS. I am pretty sure
that the processor on your x346 does not have this option - hence 64 bit guests is not possible.
Best regards
Frank Brix Pedersen
Could you post the model processor you have (e.g. Intel Core2 6400)?
Hi Frank,
thanx for the quick answer. But if i install W2008 x64 on this machine directly the server works normally only Hyper-V isn't supported. Hyperthreading in Bios is enabled and as said if i only install w2008 x64 Enterprise on the machine standalone it works. Only with ESXi installed i'm not able to install a virual machine with 64bit OS

hardware data:
2x Xeon 3.2GHz/800MHz (1MB L2 Cache),
IBM x346 Model 8840 Type 2BG - latest BIOS Updates, latest Firmware,...
sorry that i can't post the exact model of CPU but i do not see it in BIOS or Diagnostics

Those CPUs sound old enough that I doubt they support VT technology, which, as mentioned in a previous thread, is required for 64-bit guest support. You can go look up IBMs documentation on the system and see if they mention it, but I think you might be out of luck in getting 64-bit guests on that system.
Hi Nick,
as mentioned before - i am able to install w2008 Enterprise 64bit on this machine so could it be that if i install 2008 directly on the hardware i can use 64 bit and if i try to install 64 bit in a virtual machine on the same hardware the installation says Sorry - your system is not 64 bit ?!?!
really strange behavior.
Installing a 64-bit O/S onto a system is not the same as being able to run a 64-bit VM. I have a Dell PE1850 that has a Xeon processor in it (with an 800 MHz FSB) that is a 64-bit processor. I can install the 64-bit version of Windows, but I cannot run 64-bit VMs on it because the chip does not have VT. Your processor MUST have VT capability and have it enabled in order to run 64-bit VMs.
Hi Nick,
ok I think thats the reason - f... IBM - the processor supports the VT Flag but the current latest BIOS on this machine doesn't.
looks like we must use 32bit systems and wait till IBM serve a new BIOS

We have a fleet of the x346 8840 - 11M and 25 M Spec machines and are exploring what to do with them now they are getting a bit older.
I was expecting we could run ESX 4 on them but it seems not !
IBM's Doco indicates they won't run ESX4
I also fond this usefull for training and investigation

Ultimate White Box has few entriesrelating to the 8840
If any one finds a way to enable VT Support as per the last post please post it here and we'll test and advise
