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
