It is planned to add support for SPICE remote desktop to virt-manager
once that matures & is accepted into upstream KVM/QEMU. That will improve
the guest/desktop interaction in many ways compared to VNC or SDL, with
improved display resolution changing, copy+paste between host & guest,
much better graphics performance, etc. 

Development efforts aren't totally ignoring the desktop, more that they
are focusing on remoting guest desktops, rather than interaction host 
desktop since that's where alot of demand is. This benefits single host
desktops scenarios too, since there's alot of overlap in the problems
faced there.

Regards,
Daniel
