qemu spice disabled by apparmor.

[Peter Silva]

trying to get sound working for vm's under precise. Precise seems to have all the pieces needed for SPICE protocol, which looks to be an improvement. so to get it working:

virsh edit w7vm1-netflix
to edit my windows 7 image, to change the binary invoked from qemu-system-x86_64 to qemu-system-x86_64-spice
but then when I started the vm up with virt-manager, I got a dialog like so:

Error starting domain: internal error Process exited while reading console log output: libvir: error : cannot execute binary /usr/bin/kvm-spice: Permission denied

after reading /var/log/syslog... I went into /etc/apparmor.d/abstractions/libvirt-bin to add entries for spice support. (patch attached.)

I now have sound in my vm guests!

oh crap, I think the patch is backwards... you get the idea...
