virt-aa-helper: error: could not find realpath for disk

[Martinx - ジェームズ]

Guys,

I'm trying to create a VM with virt-manager, and I'm seeing the following
error on libvirt.log:

---
2014-03-08 09:22:00.800+0000: 21935: error : AppArmorGenSecurityLabel:451 :

The ISO is there, look:

---
md5sum /var/lib/libvirt/ISO/trusty-server-i386.iso


49113ff549fef31200cd667e421b466b
 /var/lib/libvirt/ISO/trusty-server-i386.iso
---

But, it is a remote mount point, like this:

---
mount | grep ISO
//fileserver/ISO on /var/lib/libvirt/ISO type cifs (rw)
---

If I umount /var/lib/libvirt/ISO and copy the ISO file into there, it
works!! The problem appeared after I tried to move the ISOs to a central
server...

The following command makes no difference:

---
aa-complain /usr/sbin/libvirtd
---

I'm using Ubuntu 14.04, upgraded yesterday.

Any tips!?

Tks!
Thiago
