I gave it a shot, and it was able to see my running libvirt VM's although it could not create one due to an obscure error of not supporting the "custom" CPU type. The running VM's are running in full virtualization so it is probably just a minor bug in Cockpit, seeing that it is after all just a libvirtd frontend in this regard. Aside from that, Cockpit looks fairly stable and it has potential, but keep in mind it is very simple.
