Self Service Portal - Can i segregate users to have access to only few VMs withing a Cloud?

Hi

I have a cloud say ABC - Contains Machines 1-10. the moment I create a tenant - it is associate to the cloud. Once done all the people under the tenant group is able to see all 10 Machines in the VMM self service portal.

My requirement is I want only 5 machines to be shown for a set of people and the remaining 5 to another set of people. Also I do not want to create two clouds to achieve this.

Please let me know if this is feasible.

Thanks,
Raghu
