just a quick note, you do not need to stop the guest node if you make any changes like quotaugidlimitWell, for the record here is the solution.
On the hardware node:
vzctl stop VEID
vzctl set VEID --quotaugidlimit NUMBER --save
vzctl start VEID
The NUMBER should be the number of users/groups you expect to have inside the ve, so "random big number". I chose 1000.

It will change in realtime
