I am installing a Linux guest on my computer. It supports VT-x, I've enabled it in the BIOS, I've turned off Hyper-V, but I haven't turned off Windows Hypervisor Platform. And, when I checked the enable VT-x for the guest, it always show an error: VT-x is not supported on this platform, continue without VT-x? Whether I clicked Yes or No, it always lead to an error. If I click Yes, it will pop up a dialog, said: VMware Workstation does not support nested virtualization on this host.
Module 'HV' power on failed.
Failed to start the virtual machine. If I click No, it will said: Failed to turn on this VM. The only thing I can do is turn off the: Virtualize VT-x for this guest, but I need VT-x turn on for this guest. Can anyone help me? Thanks! [My error][My error]
P/S: I'm a newbie to the VMWare. I don't know so much of this.
I had the same problem on my Windows 10 System with VMWare 16. It was caused by the "Container" windows feature. After switching this feature off, it worked correctly. You can verify your settings with the ones I use. Hope that it helps you to fix the problem.

Failed to open a session for the virtual machine Samsung Galaxy S6 - 6.0.0 - API 23 - 1440x2560.
VT-x is not available (VERR_VMX_NO_VMX).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
What is this VT-x and why is it needed ?
Also I can create a VM and install Linux but why can't I start any Android device on VirtualBox ?
I have genymotion successfully installed but every time I run device it gives me above error.
Any idea how to solve this issue ?
If you run Windows 8.1/10 Pro, then the problem may be related to a Hyper-V platform from Microsoft. You may try to uninstall it. Sometimes it's also needed to disable it in a terminal window (using administrator privileges) with bcdedit /set hypervisorlaunchtype off.
To sum this up :
VT-x is not available (VERR_VMX_NO_VMX).
What is VT-x ?
VT-x is Intel's technology for virtualization on the x86 platform. VT-x allows
multiple operating systems to simultaneously share x86 processor
resources in a safe and efficient manner.
Possible issues & Solutions :
VT-X is not enabled in the BIOS settings – VT-X can be disabled from the BIOS settings manually or remotely by some 3rd party applications. Solution is to enter BIOS settings at boot time and re-enable Virtualization (can be VT-x, VT-d, etc.).
The machine’s CPU doesn’t support VT-X – Although these cases are rare, there are instances where the error is occurring because the PC in question is simply not equipped to support the VT-X technology.
Hyper-V virtualization is enabled in Windows – This is perhaps the most common cause why this error occurs. Since Microsoft’s Hyper-V technology is known to conflict with VT-X, the OS will automatically disable VT-x if Hyper-V virtualization is enabled. You can disable it via "Turn Windows features on or off" menu in Windows settings. Note that one of "Virtual Machine Platform" and/or "Windows Hypervisor Platform" being enabled appear to cause the issue.
Avast update disabled VT-X – As it turns out, Avast released an update that effectively disables VT-x while the real-time protection is active unless the user enables nested virtualization from the settings menu.
Core Isolation is enabled – Core isolation is a Windows Defender Security option that is known to conflict with VT-X while it’s enabled. You can disable it from the Windows Defender options menu, or via Settings > Update & Security > Window Security > Device Security > Core Isolation Details > Turn Off

Make sure Virtualization is enabled in your BIOS and that nothing uses it already - Hyper-V is a very common issue.
Please refer x86 virtualization wiki
Hope it helps :-)
If you have enabled the mode Virtualization in the BIOS and if the problem still persists, try going to
Settings -> Update & Security -> Window security -> Device security -> Core isolation details -> Turn off
and then restart the PC and try again to review the 64-bits VirtualBox environment.
Disable "Virtual Machine Platform" and/or "Windows Hypervisor Platform" from "Turn Windows features on or off" menu in Windows settings. After just restart and open virtual box or VMware. It works for me.
Turns out Windows has a 'Virtualization based Security Guard' which needed to be disabled. I used the powershell tool to get the job done.
.\DG_Readiness_Tool_v3.6.ps1 -Disable -AutoReboot
Here's a link to the tool:https://www.microsoft.com/en-us/download/details.aspx?id=53337

It took some time and digging to figure out it was issue only with 64-bit VMs that shows above mentioned error, and not the 32-bit VMs.
Although he doesn’t mention the actual error, the root cause of his problem is in Win 10. Hyper-V is greedy and owns the “VT-x” after booting and doesn’t share with Virtual Box at all.
Here is The two solutions:
Either remove Hyper-V from Windows (if you’re not using it obviously)
via ‘Turn Windows features on of off’
Edit the BCD to start Windows with the Hyper-V (hypervisorlaunchtype
disabled) as the post illustrates.
I suggest that If you have already enabled VTX, and checked that you have vt-d/vt-x enabled in the BIOS, try resetting the VirtualBox settings or re-installing VirtualBox: it might have nothing to do with your PC/Windows configuration.
Ok, I have the most recent version of virtualbox installed, my computer (HP) has an AMD A10, 64bit Windows 10 OS and 6Gb RAM.
I created a virtual machine with Windows 7, there I wanted to create a new virtual machine (a VM2 in a VM1), but I cant run it because I have no virtualization enabled in the VM1.
ok, so I checked the VM1 configuration and the virtualization is enabled in the virtualbox settings. I've tried with all the Paravirtualization interfaces and always having the Hardware Virtualization enabled (VT-x and AMD-V).
I really don't know why this is happening if this is all suposed to be enabled and there arent documentations of similar issues.
I tried changing the number of CPUs used by the VM1 and all the interfaces.
I seach for 2 days and nothing worked for me.. then i find the solution:
The problem is in Windows 10... u need to disable Hyper-V Manager ...
1) make sure in your BIOS cpu virtualization is enable.
2) open your CMD as administrator
3) in your desktop folder type bcdedit and look for hypervisorlaunchtype in the bottom ... if it is Auto or enable we need to disable it !!!!!!
See this picture
4) type in your cmd bcdedit /set hypervisorlaunchtype off
5) Restart your OS and be happy !!!
i know this is a old question ... but for everyone who have a similar problem i hope it helps !!
Turn off the core isolation security provided in the Windows Defender Security Centre.
I found that enabling it turn off your Intel Virtualization technology feature while it is enabled in BIOS.
Steps to follow:
1. Go to Windows Defender Security Centre.
2. Search for Device Security in the left Panel and click on it.
3. Now click on core isolation.
4. Turn off the memory intergrity security.
If it didnt turn off and show (This is managed by your device Administrator) then follow the steps by searching on google.
You may need to download a file and enter into registry to turn it Off. Just google it.
The answer is correct, however there is something worth mentioning:
Usually the Hyper-V Manager is enabled by Docker (Docker runs on top of HV Manager), in my case it only worked after :
Removing Docker
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
the command line will ask you to restart, then you will able to run VX images!
In my case, my os is windows 10, I enabled virtualization VTx and Vtd in BIOS, but it didn't work. After seaching online, I sovled this problem. Hope this can help people.
Press Windows key + X and select "Apps and Features".
Then click "Programs and Features" link.
Then click the "Turn Windows features on or off" link on the left pane.
Locate "Virtual Machine Plateform" option and check it.
(These two steps I'm not sure : Locate "Hyper-V" and "Windows Hypervisor Plateform" option and unmark them.)
Click OK to save the changes and reboot.
Below is the screenshot:
enable Virtualization
And you can check if it is working fine in task manager, in the performance tab you can see whether the virtualization enabled or not.
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 installed VM ware recently now whenever i try to power on VMware it shows the below message:
"Not enough physical memory is available to power on this virtual machine with its configured settings.
To fix this problem, adjust the additional memory settings to allow more virtual machine memory to be swapped.
If you were able to power on this virtual machine on this host computer in the past, try rebooting the host computer. Rebooting may allow you to use slightly more host memory to run virtual machines."
I am not able to change the memory setting .It just shows an option to resume the virtual machine, All other options are disabled. I have by mistake increased the VM ware memory in run time .Could any one help?

Go to Control Panel -> Programs -> Programs and Features,then uninstall the Windows 8.1 Update KB2995388 may help
--* Edit *--
The Optional Update for Windows 8.1 for x64-based Systems (KB2995388) published on 10/13/2014 may causes issues when running VMware Workstation on a Windows 8.1 host with it installed.
And a message saying "not enough physical memory" will be reported.
Because the VMware team hasn't fix the issue, you can follow steps below to uninstall the update to boot your virtual machine:
1.Go to Control Panel -> Programs -> Programs and Features, then select View installed updates at the top left corner.
2.Scroll down the list and locate Update for Microsoft Windows (KB2995388), select it and click on the Uninstall button.
3.Follow the steps to finish the uninstallation.
In the comment list, someone also reported a fix from VMware communities:
Open the config.ini file located at C:\ProgramData\VMware\VMware Workstation.
Add this line:
vmmon.disableHostParameters = "TRUE"
Save & reboot your PC
It sounds like your VM machine is in a suspended state. What you need to do is follow the steps outlined here in this help ticket. Do these steps while vmware is not running. And once you do this, start vmware again and then you should be able to edit your memory settings.
Run it in Administrator mode in Windows 8.1. Probably a Windows Update... Deleting the suspended state didn't work for me.
Before proceeding with any alternative solutions/workarounds, please always double ensure you have updated to the latest version of VMWare Player.
My machine was running VMWare Player, Version 6.0.*, and this issue was occurring (my local machine's Operating System is Windows 8.1). The relevant error(s) were resolved after updating to the latest build currently available, VMWare Player, Version 7.0 (Please note: I did not have to remove/uninstall any Windows Updates/Features)
Just spent a few hours trying to get my VMware to boot. Power flickered off enough to shut down the computer while the VMware was in suspension and recieved this message.
Make sure the update isn't installed. Make sure to follow the accepted answer. What made it work for me was:
Right click on your development name tab
Click on "Manage" and then "Clean up disk"
It worked for me. I'm not sure why it worked, but it was able to fix my issue. Didn't need to restart.
Follow these steps:
Close the VMware.
Select VMware icon.
Run VMware as Administrator.
I couldn´t find any information on the documentation of VMware about this topic. Any advise on where to find information on this is very appreciated.
VMware workstation, fusion and player are desktop productions that run on top of other operating systems like windows, linux and mac os. VMware ESX, ESXi run on bare metal directly. Since VMware Infrastructure 3 is built upon ESX and ESXi 3.X, it is ok for you to run workstation on top of VI3. But it should be pointed out that workstation running on VI3 won't support hardware virtualization even if your physical cpu ships with hardware virtualization solution. However, latest ESXi and even workstation support so called "nested virtualization" in non-production environment. Actually, I have a virtual ESXi 5 server that runs within my fusion 5.
Assuming that you mean that you want to run a virtualization solution (VMware Workstation) on top of another virtualization solution (VMware Infrastructure), although I'm not sure why you would want to do that instead of simply using a single virtualization solution (either Infrastructure or Workstation, depending on what your needs/goals are), I don't believe that it's blocked. To VMware Infrastructure, the guest OS that you're running Workstation on should just look like any other guest OS, albeit one that's probably using a lot of resources.
You might find someone else who is trying to accomplish the same thing in the Workstation community.
