Recently I started having an issue with VT-x on my Windows 10 running on HP ThinkPad. I was using Oracle VirtualBox to run some VMs on it before and VT-x was enabled in BIOS and was working fine.<\/p>\n\n\n\n
I started getting VT-x is not available<\/code> error every time I was trying to start any of my VMs.<\/p>\n\n\n\n
That started happening after I installed Docker on my machine<\/p><\/blockquote>\n\n\n\n
so I tried uninstalling it and rebooting. Didn’t help.<\/p>\n\n\n\n
I checked BIOS settings and it says VT-x is enabled .<\/p>\n\n\n\n
There were no hardware changes and the only software change was installing\/uninstalling Docker.<\/p>\n\n\n\n
There are three common culprits for this type of error:<\/p>\n\n\n\n
VT-x is not enabled in the BIOS<\/li>
The CPU doesn’t support VT-x<\/li>
Hyper-V virtualization is enabled in Windows<\/li><\/ul>\n\n\n\n
There are three common culprits for the type of error the user is seeing:<\/p>\n\n\n\n
VT-x is not enabled in the BIOS<\/li>
The CPU doesn’t support VT-x<\/li>
Hyper-V virtualization is enabled in Windows<\/li><\/ul>\n\n\n\n
So, we are going to check each of these points and fix it. <\/p>\n\n\n\n
Afterwards, reboot the PC and try VirtualBox again. It should then work fine. I hope \ud83d\ude42 <\/p>\n\n\n\n
How to check if Intel Virtualization is enabled without going to BIOS in Windows 10<\/strong><\/h5>\n\n\n\n
Right-click Start > Run > msinfo32<\/em><\/p>\n\n\n\n
The first page shows whether virtualization is enabled in BIOS (firmware).<\/p>\n\n\n\n<\/figure>\n\n\n\n
How to check if the CPU support VT-x<\/span><\/h5>\n\n\n\n
Easiest option- Check your Task Manager<\/strong><\/p>\n\n\n\n
If you have Windows 10 or Windows 8 operating system, the easiest way to check is by opening up Task Manager->Performance Tab. You should see Virtualization as shown in the below screenshot. If it is enabled, it means that your CPU supports Virtualization and is currently enabled in BIOS. <\/p>\n\n\n\n
If it shows disabled, you need to enable it in BIOS. After that, If you still don\u2019t see virtualization, it means that your CPU does not support virtualization.<\/p>\n\n\n\n<\/figure>\n\n\n\n
How to disable Hyper-V virtualization<\/strong> in window (with GUI)<\/h5>\n\n\n\n
Right-click Start > Run > OptionalFeatures.exe<\/p>\n\n\n\n
You should see a list of Windows features as shown in the below screenshot. Look for “Hyper-V” and uncheck it. <\/p>\n\n\n\n<\/figure>\n\n\n\n
<\/p>\n\n\n\n
But sometime, disable Hyper-V virtualization<\/strong>, that way ist not enough, and we need to make instead the following step:<\/p>\n\n\n\n
open a command prompt as administrator and run the following command:<\/p>\n\n\n\n
Afterwards, reboot the PC and try VirtualBox again. It should work perfect now.<\/p>\n","protected":false},"excerpt":{"rendered":"
