Fix build problem - qemu.xml had some validation problems.

Fixes bug 1031327

Unfortunately the actual validation problem is often masked
by a "fake" validation problem with link linkend= internal
cross references. Had to remove two linkend internal cross
references to enable troubleshooting.

         If you are testing OpenStack in a virtual machine, you need to configure nova to use qemu without KVM and hardware virtualization. The second command relaxes SELinux rules to allow this mode of operation (https://bugzilla.redhat.com/show_bug.cgi?id=753589) The last 2 commands here work around a libvirt issue fixed in RHEL 6.4. Note nested virtualization will be the much slower TCG variety, and you should provide lots of memory to the top level guest, as the openstack created guests default to 2GM RAM with no overcommit.
