Install KVM Hypervisor on CentOS 7.x and RHEL 7.x

KVM is an open source hardware virtualization software through which we can create and run multiple Linux based and windows based virtual machines simultaneously. 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 libvirt libvirt-python libvirt-client virt-install virt-viewer bridge-utils

Start and enable the libvirtd service
[root@linuxtechi ~]# systemctl start libvirtd
[root@linuxtechi ~]# systemctl enable libvirtd

Run the beneath command to check whether KVM module is loaded or not
[root@linuxtechi ~]# lsmod | grep kvm
kvm_intel             162153  0
kvm                   525409  1 kvm_intel
[root@linuxtechi ~]#

  1. I no doubt appreciate this blog post. When you grab the information on web hosting or server, the KVM hypervisor is very important for a server managing person. Here, we have seen the full setup of a KVM hypervisor on CentOS. Onlive Server is known as a web hosting company in India. They are offered the best Singapore VPS Server services with a full setup of KVM hypervisor.

Terraform

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions. Configuration files describe to Terraform the components needed to run a single application or your entire datacenter. Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure. As the configuration changes, Terraform is able to determine what changed and create incremental execution plans which can be applied. The infrastructure Terraform can manage includes low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc. The key features of Terraform are: Infrastructure as Code : Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and...

Helm: Installation and Configuration

PREREQUISITES You must have Kubernetes installed. We recommend version 1.4.1 or later. You should also have a local configured copy of  kubectl . Helm will figure out where to install Tiller by reading your Kubernetes configuration file (usually  $HOME/.kube/config ). This is the same file that  kubectl  uses. To find out which cluster Tiller would install to, you can run  kubectl config current-context or  kubectl cluster-info . $ kubectl config current-context my-cluster INSTALL HELM Download a binary release of the Helm client. You can use tools like  homebrew , or look at  the official releases page . For more details, or for other options, see  the installation guide . INITIALIZE HELM AND INSTALL TILLER Once you have Helm ready, you can initialize the local CLI and also install Tiller into your Kubernetes cluster in one step: $ helm init This will install Tiller into the Kubernetes cluster you saw with  kubectl config current-context . TIP:  Want to install into a different cl...
