When you create a VM in DevTest Labs, you're given permission to access that VM. You can view the VM both on the labs page and on the Virtual Machines page. Users assigned to the DevTest Labs Owner role can see all VMs that were created in the lab on the lab's All Virtual Machines page. However, users who have the DevTest Labs User role are not automatically granted read access to VM resources that other users have created. So, those VMs are not displayed on the Virtual Machines page.
