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
