CentOS / Redhat: Install KVM Virtualization Software

To install the KVM (Kernel-based Virtual Machine) virtualization software on a CentOS or Red Hat Enterprise Linux (RHEL) system, you can follow these steps:

1. Install the qemu-kvm package and other required packages using the yum package manager:

sudo yum install qemu-kvm libvirt virt-install bridge-utils

This will install the qemu-kvm package, which provides the KVM hypervisor, and other required packages, such as the libvirt library and the virt-install utility.

2. Load the kvm kernel module by running the following command:

sudo modprobe kvm

This will load the kvm kernel module, which is required for using KVM.

3. Enable the libvirtd service to start automatically on boot:

sudo systemctl enable libvirtd

4. Start the libvirtd service:

sudo systemctl start libvirtd

This will start the libvirtd service, which is required for using the KVM virtualization software.

5. To verify that KVM is working, you can use the virsh command to list the available virtual machines. For example:

virsh list --all

This should display a list of the available virtual machines. If no virtual machines are listed, it means that KVM is working properly.

Note: KVM is a powerful virtualization software that allows you to create and manage virtual machines on a Linux system. Consult the documentation for KVM and the virsh command for more information on how to use these tools.

Note: Before installing KVM, you should ensure that your system meets the minimum hardware requirements for KVM, such as a CPU that supports hardware virtualization. Consult the documentation for KVM for more information on the hardware requirements.
