do not know since when but i recently realized that the 'virsh list' command shows me the first dom (the one with id 1) twice in the output List, e.g.
virsh # list
Id Name Status
----------------------------------
1 essir laufend
1 essir laufend
2 mobile-sensing laufend
3 related-work laufend
4 elisa laufend
5 lehre1 laufend
7 carina laufend
VirtManager for instance does not show the dom twice, but i encounter that several stopped machines, especially if they are newly cloned, are not shown in the VirtManager application. A restart/reload of libvirt-bin does not change this issue.
Checking with 'ps aux | grep essir' shows that the dom is only running one time.
#ps aux | grep essir

Not a serious issue but i encounter it on several hypervisors. All hypervisors running 3.2.0-40-generic with libvirt version 0.9.8.
