You don't need to (and _shouldn't_) use virt-v2v if the guest already works on KVM. It's only for importing guests which run other hypervisors like VMware, Xen or Hyper-V (or physical, via virt-p2v). Having said that, there was a problem that oVirt didn't support imports of disk images. I don't know if that feature was added yet. > Where do I have to install virt-v2v on the oVirt management host? > I've setup a RHEL 7.1 VM with the libguestfs preview for RHEL 7.2, > will this work that way.

For reference if trying to use virt-v2v to import a VMware/etc guest, there are two ways to do this. Either install virt-v2v in any RHEL 7 VM anywhere (but preferably somewhere with a good network connection to the source and destination), and use a command line like the one suggested here: http://libguestfs.org/virt-v2v.1.html#convert-from-vmware-to-rhev-m-ovirt Or with oVirt 3.6+ there is a GUI interface you can use. In that case virt-v2v is installed on a RHEV-H node, but that should be transparent to the end user. Rich.
