Fehler: Fehler beim Erstellen der Domain von deployment.0
Fehler: internal error process exited while connecting to monitor: qemu-kvm:
-drive 
file=/var/lib/one//datastores/0/18/disk.0,if=none,id=drive-ide0-0-0,format=r
aw: could not open disk image /var/lib/one//datastores/0/18/disk.0:
Permission denied

Sorry Tobias, the command I sent is not the correct one, you have to
explicitely say that you want to connect to the system socket. Do this
instead:

$ sudo -u oneadmin virsh -c qemu:///system create deployment.0
