This is a bug.  I have filed this:

https://bugzilla.redhat.com/show_bug.cgi?id=1033508

If you have Red Hat Support it would be helpful if you could get them
to escalate this so it gets the right attention.

Thanks a lot. Yes, we have a Support and we will ask them to help with this bug.

How do you think, maybe we can hack this issue quickly just putting the kernel
file (desired by libguestfs) manually to some directory on the RHEV-H file
system? /boot and /lib/modules do not contain kernels on RHEV-H.

A simpler plan would be to grab an appliance from here:

http://libguestfs.org/download/binaries/appliance/

**NB** The appliances there now will not work because they are too new
to work with libguestfs 1.16.  I will prepare a 1.16 appliance and
upload it shortly.

Once you've got an appliance corresponding to your version of
libguestfs, uncompress it into (any) directory and then set:

export LIBGUESTFS_PATH=/path/to/directory

and run libguestfs-test-tool to make sure everything is working.

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

Hey,

as you said, a workaround is to link the kernel into the right place,
e.g.:

$ ln -s /dev/.initramfs/live/vmlinuz0 /boot/vmlinuz-$(uname -r)

- fabian
