The vmware shows the error:
"Intel VT-x might be disabled if it has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting."
What should I do?
Do you happen to know whether or not you'll be needing the Intel hardware virtualization feature enabled for the Ubuntu OS?
If not, you can ignore that message.
If so, you can enable it with the following:
With the system powered off, go into VM > Settings > Hardware tab, choose Processors from the hardware list, and check "Virtualize Intel VT-x/EPT"

I'm trying to get Event-Based profiling session using AMDuProf (v3.5.677) but my setup is missing the
"Assess Performance" option
See my setup
See the screenshot from the manual (section 7.3.1)
The manual does say "Time-based" is the only supported option for Intel CPUs but I'm running on a Ryzen 5900x. Link to manual
I'm I missing something with the install ?
The only thing that showed up for me was this I disabled both "Hyper-V" and "Virtual Machine Platform", restarted and still did not see "Assess Performance"
I am trying to boot up a saved am using Macbook pro with M1 chip.
I tried the steps given at this answer. But was not able to boot up the VM. Can someone confirm this problem or already found out a solution to it?
I got the error "The virtual machine 'Ubuntu 20.04 64bit 1' has terminated unexpectedly during startup with exit code 1 (0x1)." below:
Had the same issue on Mac OS Big Sur 11.4 when I was trying to add my Ubuntu instance (on Intel tho), nothing suggested here and other topics helped.
Turned out you have to give access (Full Disc Access) to Virtual Box in Settings. Go to Settings -> Security & Privacy -> Privacy -> Full Disc Access -> plus sign (unlock it if needed) -> choose Virtual Box Application -> Open.
After that I was able to choose my Ubuntu image in Finder.

As per David Leitko's answer, VirtualBox is an x86 (more specifically, AMD64/x86_64) virtualization hypervisor. However, it appears from various discussions I've seen on this topic that many users don't really understand what this really means.
So, it means not only that VirtualBox only runs on x86 CPUs, but also that it requires all the other elements of the x86 platform. These include system memory, various bus controllers (PCI, USB), hard disk controllers, sound cards, graphics, BIOS/UEFI, etc. None of these take the same form on the Apple Silicon platform - i.e. they don't use any of the standards built up in the PC ecosystem over the last 40 years.
So, not only will VirtualBox not work on Apple Silicon, it will never work on Apple Silicon. There will never be any way to run a VirtualBox image that ran on an Intel Mac on an Apple Silicon Mac. Ever.
The canonical discussion thread on the VirtualBox forums that covers this in more detail is here.
VirtualBox is an x86 virtualization hypervisor. It only runs on an x86 platform. See https://www.virtualbox.org
While Rosetta 2 will run many x86 apps very well on an M1 Mac, virtualization products are not supported per this Apple document
I just had the exact same problem after updating my VirtualBox app on MacOS Big Sur. What worked for me was to go to System Preferences - Security & Privacy - General, and then click the Allow button to allow extensions by Oracle (first click the lock symbol in the lower left of the screen and enter your password).
Actually, during installation I got this pop-up window telling me to do this, but I wasn't quite sure what exactly it wanted me to do. Only after getting this error I took the trouble of looking closer, ahem...
Hope this will fix your problem too!
This question already has answers here:
VT-x is disabled in the BIOS for both all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)
(15 answers)
Closed 5 years ago.
I have installed Oracle VM VirtualBox 5.0.12, and now trying to start it up.
But shortly after trying to power it up, I get an error message saying:
VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)
Have other readers experienced the same issue and resolved it successfully? Please let me know. I have checked out other threads on Stackoverflow which report the same error message, and tried out the suggestions mentioned there, but none of them is working for me.
If it would help, I am running Windows 7 Enterprise edition SP1 64 bit.
Does anyone have an idea what the problem could be?
You may have virtualization disabled on the host computer. To enable:
Go to your host computer's BIOS (during reboot, press F12, or Delete, or F2, ... depends on computer).
Find some options regarding virtualization. E.g. recent Lenovo's have it under Security / Virtualization.
Enable what's there to enable. E.g. VT-d technology [Enable].
This made it work for me.
Try going to Settings -> System -> Motherboard on VirtualBox and change the RAM size.
Increase the RAM size and try to start it up again. It worked for me, hope it works for you as well!
I ran into this issue with both of my ThinkPads (T450s and X1 Carbon), but this probably applies to other machines with Intel hardware.
One solution is to enable virtualization options in the BIOS of the host machine (not the guest VM).
Reboot and enter the BIOS (F12 usually)
Navigate to the virtualization settings. The exact menu navigation may vary based on your particular BIOS and version. For me it was Security -> Virtualization.
In my case there were two options, both of which were disabled:
Intel (R) Virtualization Technology
Intel (R) VT-d Feature
Enable both options
Save and exit (reboot)
This resolved the issue for me.
When I opened Settings->System->Motherboard, suggested by the answer above, I realized that the .ova file I had downloaded into VirtualBox had settings that exceeded my old computer's RAM size (as suggested by the warning message at the bottom of the screen). Once I was within the capabilities of my machine, the system started adequately.
In my case, I had 4GB of ram for the Virtual Machine (my host machine has 8GB of ram, and I was getting that error. I've change the ram amount to 2GB ram and my Virtual Machine booted perfectly.
However, I had already enabled virtualisation on my BIOS settings.
Non of the solutions worked for me. Instead, I tried the following:
System -> Acceleration -> Uncheck Enable VT-x/AMD-V
changing the ram did not work for me so i found another solution
on virtualbox navigate to Settings -> System -> Processor and then click on (Enable PAE/NX).
this solved my problem.
First, you should check if virtualization is enabled.
You can use the free tool provided by SAS Support: http://support.sas.com/kb/46/250.html
If virtualization is not enabled, then you have to enable VT-D function in BIOS (for my Asus Motherboard it was in Advanced-->System Agent Configuration settings).
I also had to enable Intel Virtualization Technology in CPU settings.
Now everything works seamlessly.
I have faced the same issue with Ubuntu 16.04 (xenial) at Dell Latitude E6500.
First I have updated the VB and my symptom changed. There was no option to create x64 machine at all and a user friendly message box while trying to deploy an old one.
I have found a similar story described here. And this link brought me there to the final solution.
In short words, for Dell BIOS you need to keep
Performance -> Trusted Execution = OFF
I solved the problem by reducing the memory size in settings-> system
I recently installed windows 7 on VirtualBox and installed battle.net.
When I start battle.net I get this error: http://i.imgur.com/006cpRC.png
I googled a lot but I was not able to find an anwser :/
Also tried to put Windows 7 on VMWare but that resulted in me getting the same error.
Before this I tried downloading the driver for the GPU I have but then I get this error, http://i.imgur.com/kMacwB8.png
Hope you guys can help me :)
You may need to enable 3D acceleration on VirtualBox. By default it is disabled.
The steps to enable:
Right click the Windows 7 VM in Virtual Box and click Settings.
Click the Display category.
Check Enable 3D Acceleration and increase Video Memory as needed.
Install drivers:
While the VM is running, click Devices menu and then Install Guest Additions
Click Run VBoxWindowsAdditions.exe in the popup and run through the installer.
See: http://www.howtogeek.com/124479/how-to-enable-3d-acceleration-and-use-windows-aero-in-virtualbox/ for extra information.
Note that the article states the 3D acceleration is experimental and should run older games, but possibly not newer games. The article was written in 2012, so I'm not sure what the current state is. You should be able to tell if it's enabled by whether or not the Aero interface is usable.
Intel i5-2410M CPU running at 2.30 GHz running a Windows 7 64-bit operating system.
I have VirtualBox 4.13 installed.
I am trying to run ubuntu-14.04-desktop-amd64.iso but I get an error
this kernel requires an x86-64 cpu but only detected an i686 cpu
I even enabled the Intel Virtualization in the BIOS settings and then tried to use the image again but I still get the same error.
Is there any other reason why I can't use the image?
My best guess is that you somehow configured the VM for 32 bit execution instead of 64.
Can you share the XML machine configuration file (usually in your home directory - something like C:\Users\Goyuix - in a folder called VirtualBox VMs. There should be a folder for the Ubuntu VM you are creating with a file vm-name.vbox. You should be able to find an XML tag called Machine that holds that definition. Here is the relevant tag from one of my config files:
<Machine
uuid="{5c71850d-9ead-4b1f-b8b2-9f147f3a70ac}"
name="Ubuntu"
OSType="Linux26_64"
snapshotFolder="Snapshots"
lastStateChange="2014-07-19T23:16:57Z">
Pay special note to the third attribute OSType how it has a _64 at the end. I would suggest when creating a VM for Ubuntu 14.04 64-bit to use a VM type = Linux and Version = Ubuntu (64 bit).
The issue is your virtualization is disabled from BIOS setting.
I came across same issue but enabling Virtualization from BIOS worked. I am working on Windows 10. Initiallty you can disable windows Hyper option from control panel->Program and Features->Turn windows features on or off->un-select Hyper-V. save this settingsNow go to BIOS setting-> select Advance option->Here you can see virtualization option just enable this option and reboot your machine saving your settings.Delete any VirtualBox which is present earlier that caused issue. Now click on New option of your VirtualBox you can see option to install 64-bit operating systems.
