This article will demonstrates that how to install the KVM (kernel-based virtual Machines) packages on Redhat enterprise Linux 7.2 . We must have “yum repository” to install the KVM packages and it’s dependencies. There are many GUI tools available to manage the KVM. VMM (Virtual Machine Manager) is famous GUI tool which was developed by Redhat. The following table provides the KVM package names and key role of each packages. “virt-manager” and “virt-install” can be installed on any of the Linux host to manage the KVM hypervisor hosts.
KVM is a Linux kernel module that allows a user space program access to the hardware virtualization features of Intel and AMD processors. With the helf of KVM kernel modules, guests run as ordinary user-space processes. KVM uses QEMU for I/O hardware emulation. QEMU is a user-space emulator that can emulate a variety of guest processors on host processors with decent performance. Using the KVM kernel module allows it to approach native speeds. KVM is managed via the libvirt API and tools. (Example: virsh, virtinstall and virt-clone )
| Package Name | Description |
| qemu-kvm | Provides kvm.ko & kvm_intel kernel Modules . Core part of the KVM |
| qemu-kvm-common | Various BIOS and Network scripts . |
| qemu-img | Disk image manager on the host Red Hat Enterprise Linux system. |
| bridge-utils | Provides the bridges to pyshcial interfaces and VM interfaces |
| virt-manager | GUI to manage the KVM guests. Allow users to interactive with libvirtd and kernel to provide the faciltiy to create the virtual guests |
| virt-install | It’s key CLI package. Provides the binaries “virt-install” , “virt-clone”, “virt-image” and “virt-convert”. |
| libvirt | The libvirt package provides the libvirtd daemon that handles the library calls, manages virtual machines and controls the hypervisor. |
| libvirt-python | The libvirt-python package contains a module that permits applications written in the Python programming language to use the interface supplied by the libvirt API. |
| libvirt-client | The libvirt-client package provides the client-side APIs and libraries for accessing libvirt servers. The libvirt-client package includes the virsh command line tool to manage and control virtual machines and hypervisors from the command line or a special virtualization shell. |
| libguestfs-tools | libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. It can access alomost any disk image including Vmware’s VMDK & Hyper-V disk format. |
1. Check the host processors VT technology. If you don’t find vmx or svm in cpuinfo, verify that Virtualization Technology (VT) is enabled in your server’s BIOS.

- vmx is for Intel processors
- svm is for AMD processors
2.Install the KVM and KVM tools. (Ignore if the packages are already installed.)

4. virt-Manager provides the GUI to manage the KVM. You can install virt-manager anywhere either on hosts or remote systems. (This is like a vSphere Client in VMware)
