Agreed, it's very likely that users will have a homogeneous setup anyways wrt

They will be listed as a group of 10 webservers. The manager view is organized
by libvirt connections, so in the above case you would have 10 connections to
10 host (which happen to be split KVM and Xen).

The case shown in the screenshot doesn't indicate this very well, but it isn't
new behavior: current virt-manager works the same way. The connection labels
should be tweaked though to place a higher emphasis on hostname as opposed to
hypervisor type (unless we are only working locally), so I'll play with that.

That's an interesting idea. Not likely to happen in the short term though.
