A brief description of the kernel-level program developed by KVM for the VT technology CPU

KVM is a nice kernel-level program developed by QEMU with a number of CPUs that turn on VT technology.

Here are some brief instructions:

How to make sure your computer can use KVM

Intel CPU

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp;grep Vmx/proc/cpuinfo

But if you're using Intel's CPU, your computer manufacturer may have turned VT off in the BIOS. This is explained in more detail below.

AMD CPU

grep svm/proc/cpuinfo

If the above command has a return output it means that your CPU supports KVM, otherwise it is not supported.

Installing KVM and QEMU

sudo apt install KVM qemu

Load the KVM kernel module

sudo modprobe KVM

Loading Intel kernel modules

If you're using Intel's CPU

sudo modprobe Kvm-intel

Note: If you return the following error message when loading the module, the VT may be shut down in the BIOS.

$ sudo modprobe kvm-intel
Fatal:error inserting Kvm_intel (/lib/modules/2.6.20-15-generic/kernel/drivers/kvm/kvm-intel.ko): Twist not Keyword

Using the DMESG command you may find the following information at the bottom:-

Kvm:disabled by BIOS

How thoughtful it is:)

Loading AMD kernel modules

If you are using an AMD CPU

sudo modprobe kvm-amd
