[ubuntu] virt-manager 'Redirect USB Device' option not available for Ubuntu Server instance

Hi, Im trying to do USB redirection of a webcam into a headless Ubuntu 16.04 server instance created with virt-manager (Ubuntu 16.04 host). Normally, if I used Ubuntu Desktop with virt-manager, I can successfully get it to redirect into the instance via the 'Redirect USB Device' on the virt-manager menu, but for some reason this option is not available at all when the guest instance is Ubuntu Server.

I also cannot get the camera to pass through at all using USB passthrough (im not sure if its App Armor blocking me or not and not sure how to disable App Armor outright for libvirt/kvm or allow USB for all libvirt instances in App Armor).

Any thoughts as to how I could get the USB redirection to work on a Ubuntu Server instance?

Thanks,
