Modern CPUs include hardware virtualization features that help speed VirtualBox, VMware, application Hyper-V virtual machines, and more. But Intel VT-x is not always enabled by default. If not, you will see a message such as "VT-x / AMD-V hardware acceleration is not available on your system," "The host supports Intel VT-x, but the Intel VT-x off", or "processors on this computer is not compatible with Hyper-V. " Intel VT-x may come with Disabilities; AMD-V is always enabled First, it is only necessary for Intel VT-x. Hardware Intel VT-x can be disabled through the BIOS or UEFI firmware atmosphere, and regularly came with Disabilities on the new computer. AMD-V is always enabled if you use AMD processors that support, so there is a BIOS or UEFI firmware settings you must change. However, if you have any other hypervisor (such as Microsoft Hyper-V) using AMD-V, you may see a message saying it was not available. Try Uninstall Hyper-V This error message can also occur if you have Microsoft Hyper-V installed. When you brag installed Hyper-V, Microsoft's hypervisor takes over and would not let VirtualBox or VMware hardware access Intel VT-x. You will see an error message about Intel VT-x becomes unavabilable, although enabled on your computer. To resolve this problem, head to the window feature in the Windows Control Panel and remove Hyper-V. Reboot your computer and try using VirtualBox or VMware again. Yes, Hyper-V backup hardware features for it's installed. You have to uninstall it if you want to use VirtualBox or VMware together with hardware virtualization features of your CPU. No matter if Hyper-V is closed - it is the choice of hardware in the background. Accessing BIOS or UEFI Firmware You will now need to access low-level settings screen of your computer. On PCs made prior to Windows 8, this is probably the BIOS. On the PC that were created after Windows 8 came out, this is probably the UEFI firmware. On BIOS-based systems, you will need to reboot your comptuer and press the appropriate button while it is booting to access the BIOS setup screen. For example, it is often the "Delete" or "F2". It also may be "Esc", "F1" or another key. You may see a message like "Press [key} to access settings" on your computer screen while it boots. Doing a web search for the model number of the computer and "Access BIOS" or check your computer's manual if you do not find a key that worked. On UEFI-based computer, you do not need to just press a button while the computer is booting. Instead, you must follow these instructions to access the UEFI firmware settings of advanced options startup Windows 8. Hold the Shift key as you click the Restart option in Windows to reboot directly into the menu. However, once you get in, you can begin to look for Searching choice of Intel VT-x. Typically, you'll find this option under submenu processor. The menu was probably located somewhere under the "Chipset," "Northbridge", "Advanced Chipset Control", or "Advanced Configuration CPU." Looking option called "Intel Virtualization Technology," "Intel VT-x," "Virtualization extensions," "Vanderpool," or something similar. Enable the option and select "Save and exit" or similar feature to save changes to the settings and reboot your computer. What to do if you do not see the options Unfortunately, some laptop manufacturers and motherboard manufacturers can not offer options that allow you to enable Intel VT-x. The setting can be disabled by default with an option that allows you to activate it. If you do not see your BIOS options, trying to do a web search model number of your laptop (or your motherboard, if the desktop PC) and "Enable Intel VT-x". In some cases, manufacturers can then release the BIOS or UEFI firmware updates that allow this option or gives you the option to do so. Updating the BIOS or UEFI firmware can help - if you're lucky.
