I finally worked out what's going on with livecd-creator. It's
this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1182362
and the workaround is trivial: just add 'tar' to the list of
packages in the kickstart. I will add this to the p2v.ks upstream
shortly.
I'm also building a 32 bit ISO based on Fedora 22 which will
go on the website later today (if it works).

virt-p2v converts physical machines to virtual machines. Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
