Disk quota for imported VMs

Imported a bunch of Existing VMs in OpenNebula.
After import I assigned to a group a quota of 500 GB
Assigned existing VMs to that user/group
Used quota for group counts only a single VM created from inside OpenNebula.
All the imported VM storage is not counted at all.

How can I instruct it to count existing VMs in vCenter that I imported?


vCenter 6.7
OpenNebula 6.2

It only shows the 300GB for the new VM instead of 3.8 TB or so …
