Mastering KVM Virtualization

Overview of this book

A robust datacenter is essential for any organization – but you don’t want to waste resources. With KVM you can virtualize your datacenter, transforming a Linux operating system into a powerful hypervisor that allows you to manage multiple OS with minimal fuss. This book doesn’t just show you how to virtualize with KVM – it shows you how to do it well. Written to make you an expert on KVM, you’ll learn to manage the three essential pillars of scalability, performance and security – as well as some useful integrations with cloud services such as OpenStack. From the fundamentals of setting up a standalone KVM virtualization platform, and the best tools to harness it effectively, including virt-manager, and kimchi-project, everything you do is built around making KVM work for you in the real-world, helping you to interact and customize it as you need it. With further guidance on performance optimization for Microsoft Windows and RHEL virtual machines, as well as proven strategies for backup and disaster recovery, you’ll can be confident that your virtualized data center is working for your organization – not hampering it. Finally, the book will empower you to unlock the full potential of cloud through KVM. Migrating your physical machines to the cloud can be challenging, but once you’ve mastered KVM, it’s a little easie.

Deploying VMs using the clone provisioning method


Perform the following steps to deploy the VM using clone provisioning:

  1. Open the Virtual Machine Manager (virt-manager), then select the Template_CentOS virtual machine. Right-click on it and select the Clone option, which will open the Clone Virtual Machine window:

  2. Provide a name for the resulting virtual machine and click on the Clone button to start the deployment. Wait till the cloning operation finishes.

  3. Once it's finished, your newly deployed virtual machine is ready to use and you can start using it:

    KVMHOST# virsh list  --all
     Id  Name                         State
    -------------------------------------------
     24  Fed21                        running
     -   CentOS_LAMP1                 shut off
     -   CentOS_LAMP2                 shut off
     -   Template_CentOS              shut off
    

CentOS_LAMP1 and CentOS_LAMP2 are two virtual machines deployed from Template_CentOS but as we used clone provisioning they are independent; even if you remove...
