[libvirt-users] ubuntu 12.04 x64 virt-manager 0.9.1

dear experts, I have a clean kvm installation on ubuntu 12.04 x64 , when trying to create my first guest I get the following error: Unable to complete install: 'internal error cannot load AppArmor profile 'libvirt-ac760227-6849-b81e-15f6-a7eae418225f'' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1909, in do_install guest.start_install(False, meter=meter) File "/usr/lib/python2.7/dist-packages/virtinst/Guest.py", line 1236, in start_install noboot) File "/usr/lib/python2.7/dist-packages/virtinst/Guest.py", line 1304, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 2166, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: internal error cannot load AppArmor profile 'libvirt-ac760227-6849-b81e-15f6-a7eae418225f' some details: - the user used on the virt-manager connection is a memeber of the libvirtd group - using ssh key auth from the virt-manager Any Ideas?
