This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to

Comment 3 Richard W.M. Jones 2014-11-18 11:22:31 UTC 
Virt-v2v needs to run on the latest Red Hat Enterprise Linux release
to ensure it can correctly read and modify new guest filesystem
features.  A new version of virt-v2v is now available for RHEL 7.1.

Before RHEL 7.1 is released, follow the instructions here to
install unsupported preview packages on top of RHEL 7.0:
https://www.redhat.com/archives/libguestfs/2014-May/msg00090.html

After RHEL 7.1 is released, virt-v2v will be available in
Technical Preview.

You can run virt-v2v in a single virtual machine.  Other
requirements are covered here:
http://libguestfs.org/virt-v2v.1.html#resource-requirements
