Comment 1 Doron Fediuck 2017-08-06 10:00:06 UTC 
In general we do not limit HE since it's already confined by its own SD and its run time resources are important to keep it running.
What we need here is ti ensure we skip the quota tests for the HE VM and properly document this.
Comment 4 Artyom 2017-09-07 12:48:36 UTC 
Verified on rhevm-4.1.6.2-0.1.el7.noarch

1) Deploy HE on 3 hosts
2) Add master storage domain
3) Change quota mode to audit and create new quota
4) Edit HE VM description
