libvirt users - Jan 2014 - Dedicated GDM session for a virt-manager virtual machine?

Dear list,

Something has been perplexing me lately.  I have a bunch of Windows 7
virtual machines running on top of Fedora 20 in KVM using virt-manager.
 One of the big problems is that users who need the Windows VM's don't
know
how to user virt-manager and when they accidentally reboot a machine I have
to manually setup the virt-manager session for them and make it
full-screen.  That means if I'm not physically there the users are unable
to use the Windows sessions and cannot do their work.

Is there a way to create a GDM desktop session that just launches a virtual
machine via virsh and then logs directly into a full-screen virt-viewer
instance of that virtual machine?

Best,
AGS
