It could be there is another, less frequent, bug in nested KVM.
I'm assuming this is on Intel hardware?
From the libguestfs point of view what you can do is to force TCG:
export LIBGUESTFS_BACKEND_SETTINGS=force_tcg
Unfortunately this only has an effect in libguestfs >= 1.25.24. We're
going to have the new version in Fedora 20 real soon -- probably
before the end of this month. Or you can compile the Rawhide version
on F20.
