How can I tell if a specific machine has SecureBoot/UEFI as an option in the BIOS short of booting into the BIOS and visually inspecting it? Is there a way to see this information in Windows even if the option is currently disabled? Note: on Windows 7
It (UEFI support) should be reported in SMBIOS table for Type0, Bios Characteristics Extension 2, Bit3.
When I look at this bit in RW Everything, I see that my firmware does support UEFI boot.
I'll add that SecureBoot and UEFI are not the same thing. SecureBoot is just a feature of the UEFI specification. I don't know of a way to check for SecureBoot support without booting in UEFI mode first.

I want to test Intel SGX technology on my Lenovo Tower S510 10L3-000JFM. I checked via https://github.com/ayeks/SGX-hardware that my CPU Intel Core i7-6700 supports SGX but BIOS does not, or may be not enabled (in BIOS). A BIOS update can fix this. However, a recent BIOS update from Lenovo in https://pcsupport.lenovo.com/us/en/products/desktops-and-all-in-ones/lenovo-s-series-all-in-ones/s510-desktop/10kw/downloads/ds112505 does not specify that explicitly as I do not want to proceed to this risky operation without being sure.
My question is: is this BIOS update supporting Intel SGX? Or not?
Any help or resources are welcomed.
Last BIOS update is on 01/09/2016 and last CPU microcode update is on 07/01/2016.
According to a Lenovo BIOS engineer, BIOS for this computer model does not support Intel SGX and there is no plan for the future.
The Linux kernel does not transparently handle the Intel SGX. An application has to be written specifically for Intel SGX to use it.
If you just want to write code for Intel SGX, you can use the SIMULATION mode provided in the SGX SDK to write code and test it out. You won't be able to use Remote Attestation (and Local attestation) as it requires access to the hardware. Apart from that, everything should work fine.
I am trying to install android studio in my ubuntu system.But when I open the AVD manager it shows following warning message
after searching on internet I understand that I need to goto bios setup->advanced->intel virtualization technology(enable it if it is disabled),
but I can't find intel virtualization technology option in my bios setup.
bios menu
how can I solve this issue?
It seems that your board doesn't support VT-x. You are looking at the right spot I beleive. I must say, it has been a long time since I've seen such a board.
Have you correctly checked if your board supports VT-x ? Best way to find out is to check the specs of your computer/motherboard online.
Keep us posted, and good luck,
Clovel
EDIT : AMD-V / AMD IOMMU
It seems here that for AMD processors, the option you are looking for is AMD-V (VT-x counterpart) & AMD IOMMU (VTd counterpart ?). See if you can enable either one of these options in Advanced -> CPU Options
I want to check if my computer supports Virtualization Technology (VT-x). If supports, will try to turn on VT-x and install HAXM. When my computer start up, I got
Phoenix - Award BIOS CMOS Setup Utility, followed by
Advanced Chipset Features
System Info
Standard CMOS Features
Advanced BIOS Features
Boot Device Configuration
Integrated Peripherals
Can you tell me where I should go to turn on VT-x and install HAXM?
Thanks a lot for your help!
Try to google your motherboard model and find out the specs.
Or you can access your computer bios enter inside bios by pressing the delete button or the F2 button depending on your motherboard vendor.
Entering inside bios is dangerous try not to make any changes that you don't understand.
About the VT-x is usually enabled by default in all modern motherboards.
When I start a multi-core virtual device in Genymotion, I get this:
What is this virtualization technology and how can I enable it?
My CPU: Intel Core i5-4440
You'll have to turn it on in your BIOS settings as you're turning on your computer. Not all BIOS look like this screenshot, but this is one example of what you're looking for:

Enabling Intel VT-x and AMD-V virtualization hardware extensions in BIOS
Enabling Intel VT-x and AMD-V virtualization hardware extensions in BIOS
This section describes how to identify hardware virtualization extensions and enable them in your BIOS if they are disabled.
The Intel VT-x extensions can be disabled in the BIOS. Certain laptop vendors have disabled the Intel VT-x extensions by default in their CPUs.
The virtualization extensions cannot be disabled in the BIOS for AMD-V.
Refer to the following section for instructions on enabling disabled virtualization extensions.
Verify the virtualization extensions are enabled in BIOS. The BIOS settings for Intel VT or AMD-V are usually in the Chipset or Processor menus. The menu names may vary from this guide, the virtualization extension settings may be found in Security Settings or other non standard menu names.
Procedure: Enabling virtualization extensions in BIOS
Reboot the computer and open the system's BIOS menu. This can usually be done by pressing the delete key, the F1 key or Alt and F4 keys depending on the system.
Enabling the virtualization extensions in BIOS
NoteMany of the steps below may vary depending on your motherboard, processor type, chipset and OEM. Refer to your system's accompanying documentation for the correct information on configuring your system.
a. Open the Processor submenu The processor settings menu may be hidden in the Chipset, Advanced CPU Configuration or Northbridge.
b. Enable Intel Virtualization Technology (also known as Intel VT-x). AMD-V extensions cannot be disabled in the BIOS and should already be enabled. The virtualization extensions may be labeled Virtualization Extensions, Vanderpool or various other names depending on the OEM and system BIOS.
c. Enable Intel VT-d or AMD IOMMU, if the options are available. Intel VT-d and AMD IOMMU are used for PCI device assignment.
d. Select Save & Exit.
Reboot the machine.
When the machine has booted, run cat /proc/cpuinfo |grep -E "vmx|svm". Specifying --color is optional, but useful if you want the search term highlighted. If the command outputs, the virtualization extensions are now enabled. If there is no output your system may not have the virtualization extensions or the correct BIOS setting enabled.
If you have virtualization on in the BIOS/UEFI and still have issues there may be a possible Windows Hyper-V/ Virtualbox conflict
VirtualBox does not support nested hardware virtualization LINK
try disabling Hyper-V
Control Panel> Programs and Features> Turn Windows Features On or Off
Note: disabling Hyper-V will "break/disable" other hypervisors that require Hyper-V such as Native Docker for Windows
This is common issue faced by many developers for me this issue is raised when i create genymotion device for android version 5.0 and above versions
here is the solution
For ubuntu
During startup, quickly press F12 or F2.
Click on setup.
Using arrows, navigate to Intel Virtualization Technology. ( It might on the next page)
If it's disabled, then Enable it using arrow and enter key.
List item.
You'll find "Save and Exit" written on top right corner of the screen.
Now start Your system and start genymotion It will work.
If Ryzen 7 2700: reboot -> F2 or Del -> Advance mode -> CPU Configuration -> SVM = Enabled.
Default value for SVM is Disabled
Your Virtualization is disabled so you need to enable it
go to BIOS
->Restart your system and click Fn+f2
next
go to configuration
click SVM and enable it (if you have AMD processor)
or
Click intel virtual Technology and enable it (if you have intel processor)
For Windows 10 enabling virtualization go to start menu
Start menu >> settings >> update and security >> recovery >> advanced startup>>restart now
Now after restarting do following steps
choose trouble shoot option>> UEFI Firmware settings >> Restart
Then afterwards
press F10 >> Alone the menu side bar select System configuration >> Then simply enable virtual technology by clicking enter >> press F10 to save and exit >> press enter to save changes
How, in general, does one determine if a PC supports hardware virtualization? I use VirtualPC to set up parallel test environments and I'd enjoy a bit of a speed boost.
Download this: http://www.cpuid.com/cpuz.php
Also check, http://en.wikipedia.org/wiki/X86_virtualization
Edit: Additional, I know it's for XEN but the instructions are the same for all VMs that want hardware support. http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors
I can't try it from work, but I'm sure it can identify whether you've got the Intel VT or AMD-V instructions. Intel will have a "vmx" instruction and AMD will have a "svm".
On linux you can check /proc/cpuinfo, "egrep '(vmx|svm)' /proc/cpuinfo"
The first thing is to run VPC, open Options, and see if the HW virtualization option is available.
If it isn't you may still have it. Many machines have HW virtualization disabled in the BIOS. If you believe this is the case you'll need to confirm with your processor mfg that MW virtualization is supported, then find out from your BIOS mfg how to enable that feature.
#Nick what processor do you have?
Try cpu-z or SecurAble on windows or on linux, cat /proc/cpuinfo and look for the flags: vmx (Intel) or svm (AMD)
All of those will tell you if the hardware supports it, but as others said it must be enabled in the BIOS. (But checking first will avoid an unnecessary reboot...)
Try just turning the option on in VirtualPC. If it doesn't do anything (or the option isn't available), then your PC doesn't.
Try just turning the option on in VirtualPC. If it doesn't do anything (or the option isn't available), then your PC doesn't.
Some PC's require a BIOS setting to be turned on in order for this option to be enabled. I couldn't find that BIOS setting on my machine, but then again there are a lot of options to comb through. Presumably this is a CPU or motherboard chipset feature, so there must be a list of CPU's that support it.
You can take a look in the BIOS of the machine. It indicates if the machine supports hardware virtualization.
You can run programs like virtual pc even if you machine does not support HW virtualization, but if the machine supports it the program take advantage of this extensions.
Your processor does NOT support hardware-assisted virtualization, but as others have said you can still run virtualization tools.
