virt-v2v is a small program for converting guests from VMware or Xen, to run on KVM, RHEV-M or OpenStack. For RHEL 7.1, I am rewriting and enhancing virt-v2v, so it’s much faster and easier to use.
To install, follow the instructions here for setting up the yum repository, and then you can do:
yum install virt-v2v
To use it, start with the manual here that has lots of examples and the full reference documentation.
