Einav, Thanks for the questions, see inline.
@Gilad:
1. Does the 'VmCreator' Role contain the 'consume-quota' action? so when granting "VmCreator" on Data Center "DC1" to user "User1", "User1" can automatically consume any quota defined in "DC1" (including, for example, "TemplateQuota", in Mitja's case)? No, only SuperUser and DataCenterAdmin roles contains consume_quota action.
2. Related to both your previous reply and my previous reply: Can a user associate a CPU/RAM Quota to a VM that he is now *creating*, even if he doesn't have consume-quota permissions on that CPU/RAM Quota? In Mitja's case, he attempted to create a VM associated with both "TemplateQuota" and "UserQuota", while the user (maybe - depends on answer to 1) didn't have permission to consume "TemplateQuota", and the VM creation succeeded. Is that OK? Yes, you should be able to assign a VM to a CPU/RAM quota, without being a consumer of that quota, the check is done only when running the VM (when the resources are consumed).
There is a difference between User and Admin Portal: in User portal quota list is being populated by quota that can be consumed by the user, so leaving the quota unchanged will selected an appropriate quota; also while creating a VM, disk's quota is set in 'Resource Allocation' tab (see image).
@Mitja,
Please check which quota(s) are assigned to VM while consuming the resources, and who is the user performing the task. All tasks are performed by the same user (Helpdesk User).
Quotas assigned to VM by default at creation time: - RAM/CPU - TemplateQuota (as displayed in User Portal->htvm10->General) - disk - UserQuota (as displayed in User Portal->htvm10->Disks and then Edit on the disk) Quotas assigned to VM after power-on: - RAM/CPU - TemplateQuota (as displayed in User Portal->htvm10->General) - disk - UserQuota (as displayed in User Portal->htvm10->Disks and then Edit on the disk) Please see the screenshots of the quota/resources consumed by the VM. In the Admin portal, I could see, that TemplateQuota (CPU/RAM) was consumed when the VM was started by the user. Regards, Mitja
[if the answer to both questions is "no", there is a chance that Mitja discovered a bug]

In addition to the described setup: The user was also given a permission on the data center with the role VmCreator. The user is not listed as a consumer of TemplateQuota, but they have an inherited role VmCreator in the permissions tab. Could this permission be the reason the user can create and run VMs that are associated with TemplateQuota?

AFAIK, a user cannot create a VM that is associated with one (or more) quota objects on which he doesn't have consumer permissions. i.e. if the VM was created successfully by the user, and this VM is associated with TemplateQuota, and with the quota that has been created for the user (let's call it UserQuota), it means that the user has consumer permissions on both TemplateQuota and UserQuota. If the user doesn't have permissions on one of these Quota objects - the fact that the VM has been created successfully sounds like a bug to me.

Hi!
We are running engine version 3.3.0 on CentOS6 and we have come across a problem, possibly a bug. When a user creates a VM from a template, the template's quota is assigned to the VM.
Here is the setup: - quota is set to Enforced on the data center - quota is created for template purposes (TemplateQuota) - a template is created from a sealed VM with TemplateQuota assigned to it - quota is created for a user, the user is set as its consumer - the user creates a VM from the mentioned template and leaves the quota unchanged - the created VM consumes the user's storage quota but does not consume their memory and CPU quota
This way a user can create and run an arbitrary number of VMs as long they stay within their storage quota. No errors are reported in the logs.
Kind regards, Mitja Mihelic
