Can you attach the VMX file for the VM you're trying to install in?

Did you shutdown and start back up after enabling VT in the BIOS.

ESX Service Console being 32bit has nothing to do with the 64Bit support. The vmkernel is what passes through the capabilities of the hardware to the VM's.

Typically not restarting or doing a powerdown/powerup after enabling VT is what causes the issue with not being able to run 64bit guests.

Edit..not making sure you have selected the 64bit version when selecting the operating system for the VM can cause that as well...

Hi,
What Rumple says it's correct, this document helped me to realize that just simply rebooting the server it wouldn't work! I must set the VT enabled and shutdown the server, not restart it, then power on again. And it works!! it sounds silly but it works!!

Depends on what you mean by shutdown. I've rebooted, removed AC power (over at least 40 times while playing with the BIOS options). Please let me know if I'm doing something wrong here. I'm pretty sure I selected the 64bit OS for the VM because the drop down list is pretty obvious unless there are other places I must specify 64-bit. Please do let me know if there are.

I've attached the vmx file for the VM i'm trying to install Gentoo 64-bit OS onto.

I've noticed that on the host machine, when I do cat /proc/cpuinfo, I only see 1 CPU. Not sure if that might cause this weirdness:

============================

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Xeon(R) CPU E5320 @ 1.86GHz
stepping : 7
cpu MHz : 1861.966
cache size : 4096 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 10
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss tm nx lm
bogomips : 3709.33

==============

Thanks for everyone's quick response!

Hi,

Ok, in the BIOS settings, in Advanced Options, there is Intel Virtualization Technology feature (or VTx or EM64T) and it must be enabled. There's another feature, something like executable bit disable or something like that, I don't remember the exactly name, but you must set enabled too, just in case, it will help you someday with vmotion.

After making these changes, and save your configuration, your server will reboot and use "shutdown -h now", shutdown completely the server, disconnect the power like for 2 minutes, and power on the server again. That's what I did. And it works.

After this, you must be able to create either "Other 64 bit" VM or/and Win 64 bit/linux 64 bit.

Let me know your results after trying this again.

I hope this helps.

Regards.

Wow, thanx guys. Now it works. What I did was:

1) Reset BIOS settings to default
2) Unplug power for 5 minutes (just to be safe)
3) Boot up and turn Intel VT on again
4) Unplug power for 5 minutes (just to be safe)

and now I get 64-bit virtualized CPUs. You guys are great help!

I am having a similar issue but i am using Unisys ES7000/600 machines which I believe does support 64 bit. Is there any fixes for this issue for ES7000?

I have 3 hosts. Our first 2 which we started with are IBM System X3650 Type:7979AC1. These 2 systems have Intel Xeon E5440 CPU's (2 quads) Been running virtual machines on them fine and vmwotion works great. We recently added a 3rd host which is where the Vmotion problems began. The 3rd host is a IBM 3650 M2 Type:7947AC1. This server has Intel Xeon X5570 CPU's (2 quads). We cannot vmotion machines between the 2 orginal hosts and this new one. The first 2 hosts the look fine have the Virtualization Technology enabled in BIOS (no other options then just the "Virtualization Technology") The new 3rd host has the same option enabled as well. I've even tried shutting down a VM and setting that "hide CPU flag" option and still get the same problems.

We get the following errors:
