Build a 64-bit operating system on a virtual machine: This host supports Intel VT-x, but Intel VT-x is disabled, and the virtual machine vt-x

VT-Virtual Technology.

Specifically, the virtual 64-bit operating system requires enabling VT In the BIOS. Tip: This host does not support Intel VT-x, so it is impossible to virtualize a 64-bit system.

When prompted: This host supports Intel VT-x, but Intel VT-x is disabled, you only need to enable the VT function in the BIOS.

First, to enable the virtualization technology support, several conditions are required:Chipset support and BIOS support, Processor support, operating system support. Mainstream Operating Systems Support VMM management, so you do not need to consider it. In terms of chipset, it has been supported since the Intel 945 (except netbook) era, so you do not need to consider it. In terms of CPU, You can query it on the Intel official website. Therefore, you can view the supported information from the BIOS. From the current Lenovo shipments, the BIOS provided by Intel 945 and Intel 965 full range of models is not supported (or disabled) VT-x option (of course, it can be enabled using other tools, but it is very troublesome ). Some early Intel 4 series platforms cannot directly enable (or disable) VT-X options through BIOS, such as IdeaPad Y430 is a typical example. New series, such as Ideapad U330 and Lenovo 3000 G450 models, can be enabled (or disabled) VT-x by upgrading the BIOS later. In some models, when the CPU supports VT technology, the VT-x function is automatically enabled. IdeaPad Y450 is a typical example. The new Intel 5 Series platforms all support this option. Some models may support Intel VT-d technology to allow direct access to I/O by VMM, eliminating most of the performance overhead, data transmission is accelerated.

1. Phoenix BIOS Model Reference operation method: (use IdeaPad Y460 as the operating platform)
First, press the F2 hotkey at the boot self-check Logo to enter the BIOS, select the Configuration option, select Intel Virtual Technology, and press enter, for example:

Move the cursor to Enabled and press enter to confirm, for example:

In this case, the option is changed to Enabled, and then press the F10 key to save and exit to enable the VT function, for example:

2. Reference Operation Method for The Insyde BIOS model: (using Lenovo 3000 G460 as the operating platform)

First, press the F2 hotkey at the boot self-check Logo to enter the BIOS, select the Configuration option, select Intel Virtual Technology, and press enter, for example:

Move the cursor to Enabled and press enter to confirm, for example:

In this case, the option is changed to Enabled, and then press the F10 key to save and exit to enable the VT function, for example:

 
The 64-bit (linux) system cannot be installed on VMware10, prompting that the host supports Intel VT-x, but Intel VT-x is disabled

Enable intel virtualization technology (Intel VT-x) in bios)

I use vmware10 to install Fedora20 64-bit desktop, but I am always prompted that 64-bit operations cannot be performed, and Intel VT-x is disabled.

In this case, you need to enable the bios of The vt-x physical machine (host machine) in the bios. It is not a virtual machine!
