Chapter 1. Introducing V2V

Warning

The Red Hat Enterprise Linux 6 version of the virt-v2v utility has been deprecated. Users of Red Hat Enterprise Linux 6 are advised to create a Red Hat Enterprise 7 virtual machine, and install virt-v2v in that virtual machine. The Red Hat Enterprise Linux 7 version is fully supported and documented in virt-v2v Knowledgebase articles.
V2V is an acronym for virtual to virtual, referring to the process of importing virtual machines from one virtualization platform to another. Red Hat Enterprise Virtualization and Red Hat Enterprise Linux are capable of performing V2V operations using the virt-v2v command.
