Windows 7: Hardware virtualization BLOCKED - mistake by Dell ??

Hardware virtualization BLOCKED - mistake by Dell ??

Hello experts - hope you all had a great and tasty Thanksgiving - but this one is a doozy:

I have a new Dell Optiplex 7010 MT with with 8GB RAM, a 500GB hard drive and an Intel Core i5-3470 CPU @ 3.20GHz – this is a genuine quad core processor with hardware virtualization. I am dual booting Win 7 Pro 64-bit and Win 8 Pro 64-bit.

Also, I have BIOS A16 with the following settings:
Virtualization Support:
Virtualization – Enable Intel Virtualization Technology is ON
VT for Direct I/O is Enabled – ON
Trusted Execution is OFF

HOWEVER, in Win 7 Pro, I am getting ready to do XP Mode but when I first run the havdetectiontool.exe from Microsoft, it says “Hardware-assisted virtualization is not enabled on this computer”.

Hardware virtualization should be working but something is blocking it – and it’s some type of weird BIOS - hardware problem.

The MS havdetectiontool can create a detailed report - and I am pasting it below. BUT I HAVE ALREADY POWERED DOWN AND UP THE MACHINE MANY TIMES WITH THE ABOVE BIOS SETTINGS. Something is wrong. What is it?

This is the full report:

►SO WHAT TO DO ?? Hey, Dell, did you make a dumb mistake in the BIOS?

►MORE INFO:

I ran an odd test from Intel called BITS, and it showed an error in the MP Table and two errors in MSR. Don't know what that means, except that "MSR" shows in the "havdetectiontool" results I posted above.

Also, I strictly followed AGAIN the instructions above in the havdetectiontool test -

1) changed the BIOS to DISABLE the two virtualization options, did a complete power down, waited, pulled out AC plug, waited, pushed power button to discharge the capacitor, waited, connected the AC cord, waited, powered up, ran the havdetectiontool test, got the same results.

2) changed the BIOS to ENABLE the two virtualization features AND the Trusted Execution feature, did all the same power down and back up recycling and got an immediate boot error: "Alert! Invalid Trusted Execution Technology Configuration. Please refer to the Trusted Execution Technology Setup option helptext for details." But I have no idea where that helptext is. In any case, it is EXPECTED that Trusted Execution not work. But surprised it prevented boot-up.

3) Went back into BIOS, turned OFF Trusted Execution, left ON the other two virtualization options (so I'm back where I started), did the whole power off wait AC out power on again, booted OK, but same “Hardware-assisted virtualization is not enabled on this computer” message from the MS havdetectiontool test - back where I started.

Big pain in place where I sit on Michael Dell's nose.

Are you awake after reading this exciting saga? Any ideas?

Dual boot - Win 7 Pro 64-bit and Win 10 Pro 64-bit
 
 

► More info --

The Optiplex 7010 is dual-boot. At the moment, I'm in my Win 8 Pro 64-bit OS. Its "System Information" shows the following four lines:

Hyper-V - VM Monitor Mode Extensions ... Yes
Hyper-V - Second Level Address Translation Extensions ... Yes
Hyper-V - Virtualization Enabled in Firmware ... Yes
Hyper-V - Data Execution Prevention ... Yes.

I am not familiar with Hyper-V, and I certainly didn't install it on my own. I don't know why there are any references to it. But, anyway, do these four lines mean anything?

Does the machine's DEP prevent the use of hardware virtualization?

► ► More more info --

About the Hyper-V directly above:
This is probably a false clue. I happen to have dual-boot in this machine - both Win 7 Pro 64-bit and Win 8 Pro 64-bit. The four Hyper-V lines I copied above appear in msconfig ONLY when I'm in Win 8, not when I'm in Win 7.

They probably have nothing to do with my issue, which is:

How can I get hardware virtualization working on my machine?

Thanks.

►Not an answer but a really weird development.

All of the above bad news was from running havdetectiontool.exe from Microsoft while in Windows 7 Pro 64-bit. HOWEVER, when I booted into my Windows 8 Pro 64-bit, the havdetectiontool.exe says I DO have hardware virtualization!!!

So, not enabled in 7 and yes enabled in 8 - ON THE SAME PC WITH THE SAME BIOS SETTINGS !!!!!

What is this? What is the problem?

I need it OK in 7 because I want to do XP Mode in 7. What is the crucial difference between 7 and 8 on the same PC ???

One more detail: When I first tried to run the havdetectiontool.exe from Microsoft while in Windows 8, it gave me an error message that it could only run in 7, so (while staying in Win 8) I set its Properties to compatibility for 7 and Administrator privilege level. That's when it told me that hardware virtualization IS enabled. But when I ran exactly the same tool again in 7, I got the negative info posted above.

Help !!!!!

I just re-ran the verbose havtool.exe test while in Win 8 (where I have hardware virtualization), and I got the following results (pasted at bottom here).

Note the line
VmxProcessor IA32_FEATURE_CONTROL MSR value = 0x000005
How do it get it to 0x000005 when I'm in Win 7?

Please also let me know if you see any other clues in the differences between the first test above (not enabled in Win 7) and the test below (yes enabled in Win 8 - on the same PC and same BIOS !!)

Here are the test results:

To all watching this thread -

You are NOT going to believe this. I found the cause of the problem, and it's...

AVAST !!!

On my Win 8, where HAV says it works, I do NOT use Avast AV. I've been using Windows Defender.

On my Win 7, where HAV says it's not enabled, I use AVAST AV Free, and it's been at the new 2015 Avast for a while.

Over the past week, I've been thinking about this and wondering.

So today, I ran some experiments, and it's an AVAST default setting that is the villain.

Avast - Settings - Troubleshooting - "Enable hardware-assisted virtualization" has been on, so I turned it off, rebooted, and now the havdetectiontool shows "This computer is configured with hardware-assisted virtualization".

Great!!! But bloody hell !!!!

First my apologies to Dell. Mike, I just stopped eating beans and sitting on your nose.

Second, my thanks to all who have tolerated my long posts here.

Can anyone tell me why Avast's internal setting to enable HAV takes HAV away from everything else? Avast has certainly been getting sleazy the last two years, so apparently they're also not quality-testing their new versions very well.

Any thoughts? Was this supposed to happen?

After the recent snafu with Windows 8.1 Optional Update KB3000850 I'll believe it. I don't trust Avast like I used too. On my 8.1 installations I have removed avast and gone to MS Defender.

I wonder if Avast! is aiming more toward Networked workstations in businesses [where the money is] and setting defaults accordingly, makes the home user of the free version have to do more to make things run.
