You are right. This bug was fixed in the master branch using the
following patch.
https://gist.github.com/9218f1b5b5fc19bc58ec

The problem of this patch is that the CPU of these VMs will be ignored
(known issue). We will move the quota system to the OpenNebula core in
the short-term. Meanwhile I think this patch should do the trick
adding a new default param for VMs without CPU. (I have not tested
it).

Kind regards
