Several users in Cloudstack can group in a team so they can collaborate sharing virtual resources an VMs, snapshots, templates, etc. In Cloudstack this is done creating a project.
When a user creates a project becomes its administrator and can invite other users to take part on it. All members of a project can see and manage all virtual resources created by any other member. A user can be part of any number of projects.
The admin of a project can transfer its administrator role to any other project member. It can also add or remove members and erase the project. Resources created by a user that leaves the project don't disappear as any resource created inside a project belongs to the project and not to the creator.
In the project list, choose the project and click the button with the cross icon “Delete project”.
Keeps all resources without using or destroying them. Project can not be modified in any way (users can't be added,etc.)
