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.

Converting standalone KVM guests to an oVirt Virtualization platform and the OpenStack cloud


In order to convert guests from a standalone KVM system to oVirt, perform the following steps:

  1. Create an NFS export domain. Attach this to the oVirt data center. Make sure that the host acting as virt-v2v conversion server has access it.

  2. Shut down the virtual machine. Make sure that SSH is enabled on the host.

  3. Convert the virtual machine using the following command:

    #virt-v2v -icqemu+ssh://[email protected]/system -o rhev -osstorage.example.com:/exportdomain --network ovirtguest_name
    

    Note

    kvmhost.example.com/system: This is the KVM host from where the virtual machine needs to be migrated.

  4. Import the virtual machine from the export storage domain into Ovirt.

    • To convert guests from a standalone KVM system to Glance, run the following command:

      #virt-v2v -icqemu+ssh://[email protected]/system -o rhev -o glance vm001
      

    This command will convert the vm001 virtual machine Windows 7 guest to your...
