Hardware virtualization BLOCKED - caused by AVAST !!

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:

Intel VT or VIA Centerhauls processor.

►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?

► 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?

My post directly above about Hyper-V might be irrelevant. Those four lines appear in msconfig only when I'm in Win 8. They do NOT appear when I'm in Win 7. And they probably have nothing to do with the problem, which is:

What is blocking hardware virtualization on my PC?

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:

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.

I've been thinking about this and wondering. So 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?

Are you sure it is Avast? No reason for an AV to run a VM but you never know I suppose - I don't use Avast..

My guess would be Hyper-V. You thought it was a red herring but I don't think so. If you have it enabled (the feature is turned on) then it takes control of the VT-x at boot time even if you are not using it and it is then not available for other hypervisors. TPM has got nothing to do with it.

Disable Hyper-V (remove it windows add/remove features is easiest) and see if it works. You can change your boot options to enable/disable Hyper-V but if you aren't using it best just remove it.

adamf - yes, it's Avast, which I have now actually confirmed on two OSes.

Note that I don't have any problem in Win 8.1 where I am NOT using Avast at all. And I found hypervisor only in Win 8, so I don't think there's any connection.

I have the problem only in Win 7 where I am using Avast - but the problem goes away if I go into the Avast settings and UNcheck "enable hardware-assisted virtualization". I don't think there is hypervisor in Win 7 but let me know if I'm wrong.

I don't know anything about virtualization yet - haven't had enough free time. But, preliminarily, I was stymied by the negative results in MS's HAV detection tool until I found the problem.

Note that this is the new 2015 (or maybe "NG") version of Avast.

I just saw your thread here https://forum.avast.com/index.php?topic=162445.0 (I guess it is you). Sorry to have missed it.

Anyway the theory is quite straightforward. Only one program can use the VT-x instructions. If Hyper-V is installed it will take control at boot (and then you can't run VMWare, VirtualBox or other hypervisors etc in 64bit mode - you get the same error).

Apparently for some unknown (to me) reason Avast does also. So Avast has taken control and your hypervisor (XP mode) can''t run.

The detection tool is telling you if you CPU is OK and it is turned on in BIOS - not that something has grabbed it.

Good find though :)

But I think in Win 7 Avast DID grab it. As soon as I unchecked EHAV in Avast (in Win 7), the MS havdetectiontool gave good results. I already knew my CPU and BIOS were OK - the earlier negative results in the MS havdetectiontool had been driving me nuts.

Can you advise further how this works? There is room only for one virtualization system running at a a time? If so, why has Avast done what it's done? How come I'm the first person to notice?

Definitely this is so. At least only one that requires VT-x. You can run Hyper-V and VirtualBox if the VBox guest is 32 bit I believe. There are many many reports of this but for example https://social.technet.microsoft.co...7fd/hyperv-disables-vtx-for-other-hypervisors
If so, why has Avast done what it's done? How come I'm the first person to notice?
Don't know why, performance perhaps. Or sandboxing. The Avast issue has been found before though:
https://feedback.avast.com/responses/notify-users-of-the-fact-that-avast-sandbox-blocks-use-of-vt-x
windows - VT Not Supported when Installing HAXM - Stack Overflow

I don't use Avast so can't really comment but I guess you know the workaround - you need to disable it.

Only one program can use the VT-x instructions. If Hyper-V is installed it will take control at boot (and then you can't run VMWare, VirtualBox or other hypervisors etc in 64bit mode - you get the same error).

Definitely this is so. At least only one that requires VT-x. You can run Hyper-V and VirtualBox if the VBox guest is 32 bit I believe.
VirtualBox has no issues running on same computer than Hyper-V, even simultaneously. Here Vista in Hyper-V, Seven in VirtualBox:

The only issue is that when Hyper-V is enabled, VirtualBox can only run 32 bit guests.

Hi there

1) a VM if it is connected in any way to a network or even shares drives with a machine that is connected to a LAN or Internet then you need to make the same security considerations as security on a REAL machine -- to the outside world it acts exactly as a REAL physical machine does.

2) There is NO reason whatsoever to add 3rd party AV software on W8/8.1/10 --Windows defender will supply the service. It's built in to the OS - unlike W7 where there's no AV software built in which is why people use things like MSE which was a forerunner of the current security in later Windows OS'es. In fact adding 3rd party AV software to W8 etc is likely to CAUSE problems rather than resolve them.

As to what virtualisation system you use - it's up to you. I know Kari likes HYPER-V but my issue with that is that it only runs on Windows. VBOX / VMWARE for all the possible negatives do at least run on LINUX too and I can run VM's without change whether my host is Windows OR LINUX - and I increasingly run my VM's from a LINUX Host these days - particularly as I can easily boot it from an external SSD, fire up a Windows VM and have a 100% portable system.

Confirming Kari is correct though in that if you DO use HYPER-V AND another virtualisation system on Windows (in this case VBOX) then only 32 bit guests seem to work.

VMWARE workstation 11 seems to know if HYPER-V is enabled so it won't installl until you disable HYPER-V. There is a script somewhere where you can change the configuration at boot time so you don't have to keep unnstalling and re-installing HYPER-V.

Cheers
jimbo

jimbo - thanks for your detailed info, which is very helpful. Good to know I don't need Avast in 8.1. And I appreciate your info re limitations of Hyper-V.

I shall start for the first time soon to try to do virtualization - never saw it before. If there's a good guide for a noob like me (who's at least smart enough to get dual-booting going on his new Optiplex and to find this excellent forum), please suggest.

Thanks.
