KVM is known as Kernel based Virtual Machine because when we install KVM package then KVM module is loaded into the current kernel and turns our Linux machine into a hypervisor. In this post first we will demonstrate how we can install KVM hypervisor on CentOS 7.x and RHEL 7.x and then we will try to install virtual machines. Before proceeding KVM installation, let’s check whether your system’s CPU supports Hardware Virtualization. Run the beneath command from the console. [root@linuxtechi ~]# grep -E '(vmx|svm)' /proc/cpuinfo We should get the word either vmx or svm in the output, otherwise CPU doesn’t support virtualization. Step:1 Install KVM and its associate packages Run the following yum command to install KVM and its associated packages. [root@linuxtechi ~]# yum install qemu-kvm qemu-img virt-manager libvir...
