Hi Jaime,

this is my current configuration. (onehost is working, but onevm isn't. 
But when I follow the KVM configuration 
(http://opennebula.org/documentation:rel3.8:kvmg) onehost isn't working 
any longer)

oneadmin at Arbeitsrechner:~$ grep -vE '^($|#)' /etc/libvirt/libvirtd.conf
unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"

oneadmin at Arbeitsrechner:~$ grep -vE '^($|#)' /etc/libvirt/qemu.conf
oneadmin at Arbeitsrechner:~$

oneadmin at Arbeitsrechner:~$ grep -vE '^($|#)' /etc/apparmor.d/libvirt-qemu
grep: /etc/apparmor.d/libvirt-qemu: Datei oder Verzeichnis nicht gefunden

That means "not found" ;)

But I put libvirt into complain mode:

root at Arbeitsrechner:~# aa-status
[...]
2 profiles are in complain mode.
    /usr/lib/libvirt/virt-aa-helper
    /usr/sbin/libvirtd
[..]


oneadmin at Arbeitsrechner:~$ virsh -c qemu:///system nodeinfo
