Comment 15 for bug 578527

It seems I have the same error (on Lucid 64bit). I get 'opening backend "tty" failed' in my virtual machine log, and I get a kernel message in my syslog:

Aug 25 17:50:18 gaia kernel: [ 9109.444187] type=1505 audit(1282751418.474:90): operation="profile_remove" pid=10366 name="libvirt-c2d4403f-0e69-38f4-7641-ef6459dfc8a8" namespace="root"

I tried to edit /etc/apparmor.d/abstractions/libvirt-qemu, but to no avail.

I see there is a fix, but not for Lucid (0.7.5-5ubuntu27.2 seems to be current there). Any hint for how I could get this fixed under Lucid would be most appreciated.
