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.
