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.

Troubleshooting virt-v2v related issues

Here are a few points to keep in mind while troubleshooting virt-v2v:

  • Ensure that the required v2v packages are installed on the virt-v2v conversion server. For example, libguestfs-winsupport and virtio-win are installed when a Windows guest migration is planned.
  • Ensure that SSH is enabled on the source host machine.
  • Make sure that the Export Storage domain has enough space to accommodate new virtual machines.
  • Verify that the virt-v2v command syntax that is being used is correct. The virt-v2v man page has a detailed explanation of each parameter and examples are also included.

Everything fine, but the migration is still failing?

In such a situation, enabling virt-v2v debug logs will be helpful. Virt-v2v debug logs can be enabled by prefixing the virt-v2v command with the following environment variables:

LIBGUESTFS_TRACE=1
LIBGUESTFS_DEBUG=1

The following is what the command will look like:

#LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1 virt-v2v -icxen+ssh://root@vmhost...
