sometimes, though, virtualization does n’t work by rights. If you ‘re tried to set up VirtualBox or another virtualization plan and receive an error like “ VT-x hardware acceleration is not available on your system, ” try these steps to get it working again .
1. Confirm That Your Hardware Supports Virtualization
Before you start troubleshooting virtualization problems, it ‘s ache to check if your personal computer supports virtualization at all. If it does n’t, you ‘ll save yourself some clock .
Microsoft once offered a creature that cursorily checked whether your calculator could handle virtualization, but this does n’t work on modern systems. frankincense, you ‘ll need to use a tool from either Intel or AMD alternatively, depending on your central processing unit .
To check which CPU you have, press Ctrl + Shift + Esc, or right-click an vacate point on the taskbar and choose Task Manager to open the utility program. Click More details to expand it if needed, then open the Performance yellow journalism .
ultimately, choose CPU from the left number, and you ‘ll see the diagnose of your processor above the graph .
If you have an Intel CPU, download the Intel Processor Identification Utility. AMD ‘s equivalent utility is no longer officially available. Those with AMD processors should rather visit the AMD download page, select your CPU from the list partway down the page, and download the allow utility for your central processing unit .
MAKEUSEOF VIDEO OF THE DAY Install the tool for your CPU, then open it by searching on the Start menu if it does n’t open mechanically. On Intel ‘s utility, open the CPU Technologies tab and search for Intel Virtualization Technology .
You ‘ll see a check notice if your CPU supports virtualization. AMD ‘s utility should have a similar menu detailing the capabilities of your processor .
If your CPU does n’t support virtualization, there ‘s unfortunately nothing you can do to run a virtual machine. You ‘ll need to upgrade your processor, and possibly your motherboard. Most becoming modern PCs should support virtualization, indeed consider replacing your machine when you ‘re able .
2. Enable Virtualization in Your BIOS
In most cases where virtualization wo n’t work, even if your CPU supports it, the cause is that you have the feature disabled in your calculator ‘s BIOS or UEFI. Though most mod computers support virtualization, it much comes disabled by default. thus, you should take a look to make certain the proper toggle is enabled on your system .
To check if virtualization is enabled in your BIOS, visit the Performance page of the Task Manager as described above. Underneath the CPU graph, you ‘ll see a Virtualization field that lets you know if the feature is enabled in the BIOS .
alternatively, you can run a quick command in the Command Prompt. Type cmd into the Start menu to launch a Command Prompt window, then type systeminfo and hit Enter. After a moment, you ‘ll see a batch of information about your calculator. Scroll to the bottomland and following to Hyper-V Requirements, you ‘ll see a Virtualization Enabled In Firmware field .
If it says Yes or Enabled ( depending on which method you use ), then you can move onto # 4 below. But if you see No or Disabled, then you need to enter your BIOS or UEFI to enable the sport .
See how to open your BIOS right field from Windows 10 for the most reliable method, specially if your calculator boots cursorily. Depending on your machine, you might besides be able to hit a key after starting your personal computer. F2, F12, and Delete are coarse keys to enter the BIOS upon boot .
once inside the BIOS, look for an option named something like Intel VT-x, Intel Virtualization Technology, AMD-V, VMX, Vanderpool, or exchangeable. You may find it under a Processor or Chipset category, which can in turn hide under an Advanced yellow journalism .
The accurate instructions will depend on your hardware, so it ‘s worth looking up the manual for your CPU or calculator model if you ca n’t find it .
once you enable the relevant option, save your BIOS shape and boot. Upon returning to Windows, you should have access to virtualization .
3. If You Can’t Find Virtualization in Your BIOS
If the option to enable virtualization in unavailable in your BIOS, your computer credibly does n’t support this feature. however, there ‘s a gamble that the manufacturer has provided an update that adds this functionality. This credibly is n’t the case for most machines, but it never hurts to check .
An easy means to find BIOS updates is with the manufacturer app included on your personal computer. For exercise, Lenovo System Update will check for BIOS and driver updates on Lenovo systems .
If you do n’t have an app like this, you ‘ll need to manually update your BIOS. A Google search for the name of your motherboard ( or calculator exemplary ) should bring you to the manufacturer ‘s web site. There, you can normally find new BIOS versions under the Support or Downloads section .
once you download the latest update file, follow our instructions for updating your BIOS to apply it. After it completes, try entering the BIOS again and looking for a virtualization option .
If you however ca n’t enable virtualization in your BIOS, chances are that your personal computer does n’t support the have. You ‘ll need a newfangled calculator to try virtualization .
4. Disable Hyper-V (on Windows)
Professional and above editions of Windows include a Microsoft program called Hyper-V. This is Microsoft ‘s own hypervisor software, alike to VirtualBox or VMware. unfortunately, Hyper-V can hijack your calculator ‘s virtualization privileges, blocking you from using another hypervisor app .
Unless you want to use Hyper-V to create VMs, you should remove it to let your calculator run your virtualization app of choice without conflict. To do then, open the Start menu and search for turn Windows features on or off. Click the introduction that appears to open a newfangled window with a list of optional Windows functions .
In this number, you ‘ll see Hyper-V. Uncheck it and make sure all sub-boxes are cleared, then choose OK. Windows will take a moment to remove Hyper-V, then you ‘ll have to restart to complete the process .
once you ‘ve rebooted, you should be able to use VirtualBox or similar apps without seeing a message like “ hardware virtualization not supported by the host system. ” Without Hyper-V around to hog virtualization functionality, you ‘re well to go .
5. If Virtualization Is Enabled but Not Working Correctly
hopefully, you ‘ve gotten virtualization to work after following the advice above. But you even might have issues with performance or evening getting a VM started .
here are a few more tricks to try if virtualization is n’t working properly :
- Remember that you can’t run a 64-bit virtual machine on a 32-bit computer. If your processor isn’t 64-bit, make sure you download the 32-bit version of the OS you want to run in a virtual machine to avoid compatibility issues. See how to check if you have 32-bit or 64-bit Windows if you’re not sure.
- Make sure you have enough free disk space. A dynamically allocated virtual disk starts small, but expands as your VM needs more space. As this happens, your host computer could run low on space. Extremely low disk space can cause performance problems, so make sure you have cleaned up space on your PC.
- Ensure you have enough RAM to dedicated to the VM. Your VM must use some of your computer’s RAM to run. If you don’t have enough, your VM will likely chug. Take care not to share too much, though, or your host computer might run into trouble.
finally, if you ‘re using VirtualBox, you should always install the VirtualBox Guest Additions for best performance .
Get Virtualization Working Right on Your PC
hopefully, one of these tips fixed your issue and allowed you to enjoy virtualization on your personal computer. In most cases, you ‘ll equitable need to enable virtualization in your BIOS and disable Hyper-V for it to work .
If that does n’t let you at least get a virtual machine started, your personal computer does n’t support the feature—you ‘ll need to upgrade to take advantage of virtualization .
