Steps to Reproduce

1. Create two virtual machines under Virtualization->Virtual Machines, with the names of "VM-a" and "VM-b"
2. In the list of VMs in Virtualization->Virtual Machines, select the two VMs and click on "Add Components" in the bottom left

Expected Behavior

A dropdown where I can select interfaces to add to the VMs
