IMHO lxc-execute should come with a BIG warning "DON'T USE UNLESS YOU
REALLY KNOW WHAT YOU'RE DOING!" :P
Anyway, to answer you question, if you want to use lxc-execute, you
need to have lxc installed in the guets container as well. To be
accurate, you need /usr/lib/lxc/lxc-init inside the guest container.
"lxc-create" does NOT install lxc in guest container because it's not
needed for "nornal" operation (e.g. lxc-start).
