virt-manager says no hypervisor on creating a new VM

[Manish Verma]

I've upgraded to 12.04 LTS recently and I'm getting "No hypervisor options" error on creating a new VM using virt-manager.
Kernel logs says the exec to qemu-system-[x86_64/arm/microblaze/microblazeel/mips/mipsel/sparc/ppc/s390x] are denied.
{{{

We don't ship /usr/local/bin/qemu-system-s390x.
You probably need to adjust the libvirt apparmor profiles for your custom installation.

Since this isn't a bug in Ubuntu, I am closing it. Thanks.
