Downloaded Xamarin Android Player and with >>next>> progress installed Virtual Box.
When I tried to start an emulator I got
Failed to initialized device (name Of the emulator)
VboxManager Commendt Failed
and the detail of the error in Oracle Vm Virtualbox is
VT-x is disabled in the BIOS for both all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)
How can I fix this?
I have found the solution of my problem, put some images to help others, thanks

It is a RAM related issue. The documentation is self explanatory:
You are trying to allocate >3GB of RAM to the VM. This requires: (a) a
64 bit host system; and (b) true hardware pass-through ie VT-x.
Fast solution
Allocate less than 3GB for the virtual machine.
Complete solution
Make sure your system is 64 bit.
Enable virtualisation in your host machine. You can find how to do it here or there are many other resources available on Google.
Turning PAE/NX on/off didn't work for me. I just needed to turn on virtualization on my computer. I was working on a HP Compaq 8200 and followed the steps below to turn on virtualization. If you are working on a different computer, you probably just need to look up how to turn on virtualization on your pc. The steps below for HP Compaq 8200 (or similar) is copied verbatim from the comment posted by the user qqdmax5 on Hp discussion board here.
To run Oracle VM Virtual Box / VMware machines on 64-bit host there is a need to enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
Usually these setting are disabled on the level of BIOS.
To enable VTx and VTd you have to change corresponding settings in the BIOS.
Here is an example how to do it for HP Compaq 8200 or similar PC:
Start the machine.
Press F10 to enter BIOS.
Security-> System Security
Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
Save and restart the machine.
There is also some discussion on this on askubuntu.
In Virtual Box "Settings" > System Settings > Processor > Enable the PAE/NX option. It resolved my issue.
I had this issue when tried to run a 32-bit OS with more than 3584 MB of RAM allocated for it. Setting the guest OS RAM to 3584 MB and less helped.
But i ended just enabling the flag in BIOS nevertheless.
Follow the steps below in Oracle VM VirtualBox Manager:
Select the Virtual device and choose Settings
Navigate to System and click the Processor tab
Tick the check-box, Enable PAE/NX
Click OK and you are done
To verify, start the Virtual device from Oracle VM VirtualBox. If all has gone well, the device boots up.
Close this device and open it from Genymotion.
For latest Windows 10 (HP & Intel motherboard/processor),
Follow the below steps, starting with :
Settings ->
Update & Security ->
Recovery ->
Advanced startUp -> Restart now
F10 (System Recovery) -> System Configuration tab -> Virtualization Technology
Enable
F10 to save and exit
For Ubuntu on HP (Intel processors),
Press F10 on booting the system, it will enter into system setup mode.
You will find tabs on top like Main, Security, Advanced.
Go into Advanced >> and click on System settings.
Mark the check boxes on Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
Back to Main, click on save changes and exit.
enable PAE/NX in virtualbox network config
My BIOS VT-X was on, but I had to turn PAE/NX off to get the VM to run.
You need to enable virtualization using BIOS setup.
step 1. Restart your PC and when your PC booting up then press your BIOS setup key (F1 or F2 or google it your BIOS setup key).
step 2. Go to the security menu.
step 3. Select virtualization and enable it.
Note:- BIOS setup depends on PC Manufacturer-brand.
If you're on 32-bit machine don't allow more than 3584 MB of RAM and it will run.
I had to turn PAE/NX off and then back to on...voila !!
Make sure Virtualization is enabled in your bios.
Simply check how many CPUs you are allocating. With one CPU you do not need to play with your bios.
Open your BIOS and enable virtualization.
I am currently running Twincat 3.1..4022.16 on Hyper V virtual machine.
I am able to correctly build my project but when activating configuration I am getting realtime startup isolated cpu fail.
Attached is my Realtime setting and the error.
Any leads to solution will be highly appreciated.
I got the following errors when trying to activate my configuration using TwinCAT 4024.10.
Severity
Description
Error
'TwinCAT System' (10000): Sending ams command >> Init4\RTime: Start Interrupt: Ticker started >> AdsError: 4132 (0x1024, RTIME: incompatible software detected) << failed!
Error
'TCRTIME' (200): start of real-time avoided by "HyperV"
Solution
The issue was caused by the fact that I had earlier tried to get Docker working on my laptop. In order to get Docker to work I had to enable a bunch of Hypervisor options. After realizing this I reverted these by doing the following:
Press the windows key and start typing "Turn Windows features on or off"
In the following menu, make sure "Virtual Machine Platform" and "Windows Hypervisor Platform" are deselected. In case either option was selected, deselect it and restart your computer for it to take effect.
I found this on the Beckhoff website:
The runtime environment cannot be started inside a Hyper-V
environment. This refers in particular to virtual Hyper-V machines,
which are run in a privileged Hyper-V machine. As soon as a component
of the computer uses Hyper-V, only the engineering environment (XAE)
can be used on this computer, not the runtime environment (XAR). Apart
from software solutions for virtual machines, you can also use
operating system means (Device Guard, Credential Guard,
virtualization-based security, etc.) or other Hyper-V programs.
Link
Read available number of CPUs from the Target, then change number of Isolated Cores from 0 to any higher number (most cases 1) and decrease number of Cores that are dedicated to Windows.
After that click Set on target.
Here's link to detailed article about Twincat and Virtualization
alltwincat.com/2018/06/14/twincat-virtualization/
This is a supplement to Roald's answer.
If you already deactivated Virtual Machine Platform, Windows Hypervisor Platform and Microsoft Defender Platform Guard and still doesn't work, chances are you have virtualization-based security enabled. You can check it by typing msinfo on windows search box.
To deactivate it, type Core Isolation on the windows search box and deactivate Memory Integrity. Restart the machine and run ms info again to make sure that VBS is off.
Go to Twincat, activate your project and witness a miracle!
If none of the above solutions worked, try to uncheck the below settings in Windows 11:
Privacy & security > Windows security > device security > core isolation > memory integrity >> off
Supplement to Felipe's and Roald's answer: latest offender prohibiting TwinCAT from starting is yet another virtualization feature: Windows Sandbox. Can be turned toggled in the Windows Features dialog accessible from Start->Turn Windows features on or off.
I've installed Docker and I'm getting this error when I run the GUI:
Hardware assisted virtualization and data execution protection must
be enabled in the BIOS
Seems like a bug since Docker works like a charm from the command line, but I'm wondering if anyone has a clue about why this is happening?
Before you ask, yes, I've enabled virtualization in the BIOS and the Intel Processor Identification Utility confirms that it's activated. Docker, docker-machine and docker-compose all work from the command line, Virtualbox works, running Docker from a Debian or Ubuntu VM works.
There's just this weird issue about the GUI.
My specs:
Windows 10 Pro x64 Anniversary Edition
Intel core i5-6300HQ # 2.30GHz
If the features described are enabled, the problem is with Hyper-V that is disabled or Hypervisor agent not running.
SOLUTION A (If Hyper-V is totally disabled or not installed)
Open PowerShell as administrator and
Enable Hyper-V with
dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
SOLUTION B (If Hyper-V feature is already enabled but doesn't work)
Enable Hypervisor with
bcdedit /set hypervisorlaunchtype auto
Now restart the system and try again.
SOLUTION C
If the problem persists, probably Hyper-V on your system is corrupted, so
Go in Control Panel -> [Programs] -> [Windows Features] and completely uncheck all Hyper-V related components. Restart the system.
Enable Hyper-V again. Restart.
NOTE 1:
Hyper-V needs hardware virtualization as prerequisite. Make sure your PC supports it, if yes and still won't work, there is the possibility your BIOS is not configured correctly and this feature is disabled. In this case, check, enable it and try again. The virtualization features could be reported under different names according the platform used (e.g if you don't see any option that uses virtualization label explicitly, on AMD you have to check SVM feature state, on Intel the VT-x feature state).
NOTE 2:
Hyper-V can be installed only with some version e.g.:
Windows 10 Enterprise; Windows 10 Professional; Windows 10 Education.
Hyper-V cannot be installed on cheaper or mobile Windows versions e.g.:
Windows 10 Home; Windows 10 Mobile; Windows 10 Mobile Enterprise.
Below is working solution for me, please follow these steps
Open PowerShell as administrator or CMD prompt as administrator
Run this command in PowerShell-> bcdedit /set hypervisorlaunchtype auto
Now restart the system and try again.
cheers.
In my case I had to enable virtualization in the BIOS setting.
Restart PC
While you are on the 'restart' screen press any of these keys and you enter the bios settings in windows: esc, f1, f2, f3, f4, f8 or delete
For intel based systems:
press f7 (advanced mode)
go to advanced
cpa configuration
enable virtualization
And after all above steps, it finally works :-)
Note: If your version of Windows supports Hyper-V, you can install docker directly by selecting Use Hyper-V during installation.
However, if your Windows does not have this support, follow the solution below.
I had a similar problem.
I have enabled Intel Virtual Technology in the bios settings.
Then I updated the Linux kernel from here.
and it worked
My specs:
Microsoft Windows 10 Home x64 Single Language
Intel(R) Core(TM) i5-7300 # 2.50GHz
I uninstalled Intel HAXM and VirtualBox, Docker now runs
For me, all I had to do it uninstalling VMware.
Docker now is running
Open the task manager and click on the performance tab. If virtualization is disabled, you need to follow the instructions here to enable it: https://blogs.technet.microsoft.com/canitpro/2015/09/08/step-by-step-enabling-hyper-v-for-use-on-windows-10/
If solution above does not work, then
Go to command prompt and type systeminfo. check Hyper-V Requirements section.
If all listed Hyper-V requirements have a value of Yes, your system can run the Hyper-V role.
In my case virtualization enable in Firmware was NO.
So, I did enabled in system bios by making Virtualization Technology enabled in my HP laptop.
Please visit this link to enable it:
https://2nwiki.2n.cz/pages/viewpage.action?pageId=75202968
Try these steps
Run this command in powershell
bcdedit /set hypervisorlaunchtype
auto
Restart your PC
Now try docker --version in cmd line
Can you try enabling Hyper-V manually, and potentially creating and running a Hyper-V VM manually? Details:
https://docs.docker.com/docker-for-windows/#/what-to-know-before-you-install
https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/quick_start/walkthrough_install
Enable the Hyper-V role through Settings
Right click on the Windows button/Icon and select ‘Apps and Features’.
1- Select Programs and Features on the right under related settings.
2- Select Turn Windows Features on or off.
2- Select Hyper-V and click OK.
follow the steps bellow:
go to: windows setting => Update & Security => Recovery => Advanced Startup and click on : Restart Now.
Troubleshoot => Advanced Option => UEFI Firmware => Restart.
go to Bios => configuration => Virtualization technology => enable it.
save change and it will works.
It helped me:
Disable components Virtual Machine Platform and Windows Subsystem for Linux
Restart
Enable components
Restart
I think my problem was related to beta version of WSL2.
I tried to install android subsystem. But I have deleted it some time ago. So, there was only beta WSL2 left
In my case I had to uninstall hyper-v, restart pc, and run docker again.
Try this in PowerShell(admin enabled):
Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart
This will install HyperVisor without management tools, and then you can run Docker after this.
I also use vagrant. It appears I can only use 1 thing at a time. Uninstalling vagrant/virtualBox allowed me to run docker and vise versa
I have tried many suggestions above but docker keeps complaining about hardware assisted virtualization error. Virtualization is enabled in BIOS, and also Hyper-V is installed and enabled. After a few try and errors, I eventually downloaded coreinfo tool and found out that Hypervisor was not actually enabled. Using ISE (64 bit) as admin and run command from above Solution B and that enables Hypervisor successfully (checked via coreinfo -v again). After restart, docker is now running successfully.
If everything is fine with BIOS option I just forced disabling and enabling all HyperV features and this solved my issue
--cmd
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
--restart
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V –All
In my case even though I used all the solutions mentioned above but nothing worked for me. So I decided to uninstall docker and install it again.
Now in the process, I have noticed that I did not check Use Windows containers instead of Linux containers (this can be changed after installation) in my previous installation, and that is why I got the problem above and the solutions still did not fix it. So ensure to check it before you run desktop docker or uninstall it and install it again by checking this option.
I had the same issue after installing VMWare, I uninstalled it but this didn't fix the issue.
Solution for me: in "Turn windows features on or off" I turned off:
hyper-v
containers
windows subsystem for linux
then restart
After the restart I got this message from docker:
I ran the ran the command as said in the message
Enable-WindowsOptionalFeature -Online -FeatureName $("VirtualMachinePlatform", "Microsoft-Windows-Subsystem-Linux")
Then restart and voilà, Docker was back with WSL2
For me, disabling and then enabling Virtualisation in BIOS helped, strangely.
Issue for me was solved when I uninstalled Cygwin.
I tried many of the suggestions here, but did not manage to get it running. What worked for me in the end was to go straight in to the BIOS to activate it. The following article was of great help:
https://www.nextofwindows.com/how-to-enable-configure-and-use-hyper-v-on-windows-10
#Silverstorm
I had Hyperv installed and virtualization enabled in my BIOS.
But SOLUTION A didn't work for me.
However, SOLUTION B worked like a charm.
SOLUTION B (If Hyper-V feature is already enabled but doesn't work)
Enable Hypervisor with
bcdedit /set hypervisorlaunchtype auto
Now restart the system and try again.
Besides the original answer, I have done the following:
Disable Hyper-V in Windows Features
Turning virtualization off and on in BIOS
Log back in windows, enabled Hyper-V. I was prompted there are updates for Hyper-V and I did the update. Restart when prompted.
It worked!
If the problem persists probably Hyper-V on your system is corrupted, so
Go in Control Panel -> [Programs] -> [Windows Features] and completely uncheck all Hyper-V related components. Restart the system.
Enable Hyper-V again. Restart.
In my case virtualization is disabled so I need to do some configuration in my bios,
Please check following link I think it will help you to make bios setup
https://support.bluestacks.com/hc/en-us/articles/4409279876621-How-to-enable-Virtualization-VT-on-Windows-11-for-BlueStacks-5
In bios the setting are dependent on your system manufacture so please find setting accordingly.
Hope it will help you and save your time.
Thanks :)
On AMD machines the BIOS setting you have to change might be called SVM Mode. That was the case for my Gigabyte X570 board.
Setting is found in BIOS at: Advanced mode -> Tweaker -> Advanced CPU Settings -> SVM mode (set to enabled)
AMD-V is the renamed trademark for Secure Virtual Machine Mode (SVM).
I don't know how this works, and I don't even know what these commands do, I don't know what is hypervisor or what it does that it interferes with Docker, and I don't know what the nx means in the second command which it is apparently turning it off. I had these commands saved on my computer as "Turn VT-x off" (yet another thing that I don't know what it is, I think it's related to Virtualization Technology which I don't know what that does/is either). But nothing else worked for me (including the accepted answer (which I tested all of it's solutions) and other upvoted answers, although I didn't read all of them), except running both of these. It is completely up to you to test these, I do not guarantee any fixes to you, but it worked for me, I put it in here because I thought it might be helpful for someone else like me who also didn't find other answers to be that helpful:
bcdedit /set hypervisorlaunchtype auto
bcdedit /set nx AlwaysOff
shutdown /s
On 10th Jan'2023, I faced the same issue. After that, I untick windows subsystem for Linux and Hyper-v and restart my pc. Then I open the docker desktop and when it notify me to turn on Hyper-v then I did that and after that, it was working well.
Emulator not running
I am using windows phone sdk 8.0 but I am unable to run emulator in visual studio 2012, is there any case to run it,
I checked my machine and its SLAT capable...
I tried using various links provided but IT would be great help if any ne give me a direct solution, I check the Hyper-v also not enabling in the windows turn on and off features.
You probably forgot to enable in the BIOS:
Hardware-assisted virtualization.
Second Level Address Translation (SLAT).
Hardware-based Data Execution Prevention (DEP).
or you don't have:
4 GB or more of RAM.
64-bit version of Windows 8 Pro edition or higher.
Based on the wording of your question I'm guessing you have a problem with enabling Hyper-V. Even if your computer is SLAT capable, you still need to enable it along with DEP and hardware-assisted virtualization in the BIOS like Goran said. This procedure is slightly different for AMD and Intel computers. The full information is here in the "Enabling BIOS settings required by Hyper-V" section.
http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj863509(v=vs.105).aspx
Also just to be sure you don't actually need 4gb of RAM :). I only have 3.
IF you have gone through this whole procedure, sometimes you will still get an error that you are not part of the local Hyper-V administrators group. Just click retry and enter the admin password and everything should be ok.
