Matt's actually off today, but I'm sure he'll answer in more
detail tomorrow.

However the reason for getting this error is that your guest isn't one
of those supported by virt-v2v (which is roughly: RHEL 3/4/5/6 and
clones, Windows XP and above, Fedora).  If virt-v2v doesn't understand
the guest, it tries only a very minimal and conservative form of
conversion.

It's not clear what this PXE5-test guest is.  You can find out by
using virt-inspector (on RHEL 6, replace 'virt-inspector' with
'virt-inspector2'):

  virt-inspector -a /path/to/PXE5-test.img

For examples see:
