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.

VMware guest conversion


Let's see how to move virtual machines from the VMware vSphere platform to a KVM hypervisor.

Converting a VMware vSphere guest to a standalone KVM host

To convert a virtual machine to a standalone KVM host, perform the following steps:

  1. Run the following command, using values from your system. In this example, esxhost1.example.com is the VMware vCenter server, VM001 is the name of the virtual machine, and /var/tmp is the local repository to store the image:

    # virt-v2v -ic vpx://[email protected]/Datacenter/esxi "vm001" -o local -os /var/tmp
    
  2. On running this command, virt-v2v will ask for the password for [email protected]. You can enter the password interactively or by using the --password-file option.

Note

In non-production environments, the VMware vCenter server may have a nonvalid certificate, for example, a self-signed certificate. In this case, certificate checking can be explicitly disabled by adding ?no_verify=1 to the connection URI, as shown in the...
