[virt-tools-list] [PATCH V2] virt-manager: enable direct interfaceselection

Defining a virtual machine or host?  We need a way to add a 'connection'
i.e. host to virt-manager with 100% CLI for automation.  Virsh -c
invokes the GUI.  There should be away to add a KVM host to virt-manager
that does not require any interactive effort.  If not, that is a feature
that is missing that should be added.

VMware vCenter has CLI support to add host via their API, so does
Hyper-V, etc.  The way to drive KVM adoption is via automation.  No?
