Additional information: 

syslinux-extlinux is shipped in optional channels today.
livecd-tools does *not* require extlinux, but the tooling fails without the extlinux package installed.

Options as I see it:

Fix livecd-tools so that it works without extlinux (probably too big a change for 6.5/6.4.z

update 6.4.z livecd-tools so that it requires syslinux-extlinux and also ship syslinux-extlinux in the RHEV-H channels alongside livecd-tools.

Document that people need to enable the Optional Channel and manually install the package

Don't allow people to use USB to install RHEV-H <-- not really an option...
