- I have installed KVM using the instructions given on the wiki. However, when I try to check its version using kvm -version what I get as output is this QEMU emulator version 1.2.0 (qemu-kvm-1.2.0+.
- QEMU for Windows is experimental software and might contain even serious bugs, so use the binaries at your own risk. History 2019-08-15: New QEMU installers (4.1.0).

A KVM VM needs to use KVM's own CPU emulation rather than qemu's in order for me to get Windows 7 installed. I'm not sure whether there is something that can be done to get it working on a qemu-emulation CPU, or whether a newer version will support it.
what is different between the following type i get qemu-kvm ? boths are use centos 6.4.
- yum install qemu-kvm ,then show the version:[root@centos6 qemu-kvm]# /usr/local/bin/qemu-system-x86_64 --versionQEMU emulator version 1.2.50 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard
- get the source code and build it by gcc.[root@centos6 qemu-kvm]# /usr/libexec/qemu-kvm --version

Qemu uses 2 kinds of cpu virtualization, TCG (tiny code generator) and KVM. TCG emulates all instruction of guest code with plain c code, it translates guest code to host code in real-time. While KVM lets the host directly runs guest code, KVM requires the guest and the host to have the same instruction set (basically, the same cpu), not every cpu can do this, for intel cpus, it requires VMX feature. Which I assume you have understood these. Geforce 5200 windows 7.
Qemu-kvm is obsolete, KVM comes with QEMU now if you download the latest code, you just have to compile it with '--enable-kvm' option. Your QEMU source code is very old, the latest version of QEMU is AFAIK, 1.7.
Your yum source provide 1.2.50 version of qemu. Try 'yum install qemu', and try running with -enable-kvm if you don't want to build from source code (I haven't tried though).

Qemu is Hypervisor.KVM isn't. It is an accelerator(linux module which does the code translation fast) and used with Qemu, because Qemu when used with TCG is slow.

In this article, we will examine the KVM and QEMU allow to use virtualization technology on Linux systems and how to install them on Linux systems.
How to Use KVM and QEMU
What is KVM?
KVM (Kernel-Based Virtual Machine) is an open-source and virtualization solution for Linux kernel. KVM provides a complete virtualization solution by enabling hardware acceleration on processors with Intel VTx and AMD-V technology.
In addition, KVM requires QEMU to use full virtualization capability.
For more information on this virtualization solution, visit the website: https://www.linux-kvm.org/page/Main_Page.
What is QEMU?
QEMU (Quick EMUlator) is an open-source and complete system emulator. You can run and use systems such as Windows and Linux on the QEMU emulator program. This virtualization solution was also developed to work on different hardware platforms and provides a Hypervisor Type 1 virtualization solution using KVM for hardware acceleration.
QEMU can run ARM software on an x86-based computer. An example of an ARM software is the operation of an Android emulator on Eclipse software used by Android software developers. Click here to learn more about what ARM is.

What’s the Difference?
Now let’s explain the difference between these two structures. These terms often used together.
The difference is that KVM is a virtualization solution for Linux systems. QEMU creates a GUI for the KVM.
A virtualization solution with QEMU requires a KVM.
How to Install it?
Qemu Kvm Version Update
Configuring KVM/QEMU on a Linux-based Ubuntu, Debian, Linux Mint, Fedora, Kali Linux and openSUSE systems is simple and easy.
When creating a new virtual machine after installation, you can select KVM and QEMU as Virt Type.
Running it on Ubuntu 18.04
For installation on Ubuntu 18.04 (Bionic Beaver), first, open the Terminal by pressing CTRL + Alt + T and follow the steps below.
Qemu Kvm Version 10
Step 1
To install it on Ubuntu 18.04, type the following command in Terminal and press Enter.
NOTE: The Libvirt-bin package split into two parts in version 18.10, so execute the command below to install it on Ubuntu 18.10 or 19.04.
Step 2
Press Y to confirm the installation, then press Enter.
Step 3
After installation, open Ubuntu Launcher Find and run Virtual Machine Manager.
Step 4
You can check the Virtual Machine Manager version in Help / About.
How to Configure Virtual Machine Manager in Linux ⇒ Video
You can watch the video below for installation on Linux / Ubuntu 18.04 and also subscribe to our YouTube channel to support us.
Running it on Ubuntu 18.10
Ubuntu 18.10 (Cosmic Cuttlefish) is currently in beta. You can follow the above steps, in the same way, to install it on this release.
- ping -c 2 www.google.com
- sudo apt-get install qemu-kvm qemu virt-manager virt-viewer libvirt-daemon-system libvirt-clients
