So hang on, you're running virt-p2v in a VM?

While we do sometimes run virt-p2v in a VM do operational testing of
P2V, this isn't the way to convert a physical machine.  You have to
burn the ISO to a CD and boot the physical machine using it.

(Alternatives exist: use livecd-iso-to-pxeboot; or possibly your blade
hardware will let you use the ISO directly as a virtual CD-ROM)

Anyway, running virt-p2v in a VM isn't going to work ...
