What you'll learn

  • Understanding on KVM
  • KVM administration
  • Install and configuration of the KVM
  • Performance monitoring and troubleshooting of the KVM

Course content

3 sections • 23 lectures • 3h 34m total length

  • KVM Installation on CentOS79:29

    Install KVM on CentOS 7 by verifying virtualization support, enabling BIOS, and installing qemu-kvm, libvirt, libguestfs-tools, and virt-install; then configure libvirt and virbr0 for VM management.

  • Network: New bridge creation11:56

    Create and manage new virtual bridges in a CentOS KVM environment, configuring clusternet and management01 with NAT for VM internet access via a physical interface, using virsh commands.

  • VM deployment: CentOS and Ubuntu24:01

    deploy a new virtual machine in a KVM environment, enable IPv4 forwarding on the host for a NAT-managed network, and install CentOS 7 from a downloaded ISO or local repository.

  • KVM connect VM to second Network7:19

    Learn to manage KVM networking by listing virtual machines with virsh --all, viewing domain interfaces, and connecting a VM to a second network, including attaching, IP checks, and detaching networks.

  • VM Basics administration tasks7:33

    List and manage virtual machines in a KVM environment by starting, stopping, and destroying VMs, using graceful shutdowns, and verifying running versus all VMs, plus accessing VM consoles.

  • VM cloning3:29

    Learn how to clone a virtual machine in Linux KVM by stopping the source VM, creating a new clone from the original, and managing images and network bridges.

  • VM Snapshot tasks4:38

    Learn to create and manage VM snapshots in a KVM environment, including naming, describing, and listing snapshots. Revert to a chosen snapshot and delete unwanted snapshots to maintain domain stability.

  • Add new disk to VM12:51

    Learn to add a new disk to a vm by creating and attaching a disk image, formatting and partitioning it, and configuring a permanent mount.

  • KVM Remove disk from VM2:59

    Remove a disk from a KVM virtual machine by detaching it; avoid doing so while the VM runs. Stop the VM, detach the disk, then remove it from the server.

  • Increasing resources on of Guest Virtual Machines4:43

    increase the memory of a guest virtual machine by shutting it down, editing the domain memory entry in the XML, doubling the 4G value, and restarting to verify the new configuration.

  • Retreive Virtual Machine informations6:47

    Learn to retrieve virtual machine information in Linux KVM by listing block devices, disk sizes, and network interfaces. Connect to the server to inspect interface status and traffic.

  • Secure remote access to host server: SSH Acces with key17:33

    Secure remote access to a host by hardening the server, generating and using SSH key pairs, configuring iptables, and disabling password login, then verifying key-based SSH access.

Requirements

  • Basics idea on Hypervisor
  • Basics of any Linux/Unix distribution.

Description


KVM (Kernel based Virtual Machine) is the virtualization solution for Linux. It consist of a loadable Kernel module that allows the Linux Kernel to work as a Hypervisor. KVM provides hardware-assisted virtualization for a wide variety of guest operating systems.

Under KVM, each VM is a Linux process that is scheduled and managed by the kernel and has private virtualized hardware (i.e CPU, network card, disk, etc.). It also supports nested virtualization, which allows you to run a VM inside another VM.

In this course, we are going to cover the objectives on KVM ( Kernel Based Machines) , we will discuss the following topics with appropriate LABs at end of the session :

Quick Introduction to Hypervior and KVM :

  • What is a Hypervisor ?

  • KVM Quick Intro , its Pros/Cons and Terminology

KVM Installation and Configuration

  • LAB Details, Pre-Reqs for KVM Installation

  • KVM Installation

  • KVM Network Configuration

  • KVM Storage Pool Configuration

Creating Guest Virtual Machines

KVM Administration

  • Management of Guest Virtual Machines

  • Backup (Snapshots) of Guest Virtual Machines

  • Expanding the disk sizes of Guest Virtual Machine

  • Guest Virtual Machines Snapshot Create/Restore

  • Renaming a Guest VM

  • Increasing resources on of Guest Virtual Machines

  • Cloning a guest VM

  • Troubleshooting the KVM issues.

  • VM restore

  • KVM vBridge creation (Host Only and NAT)
