Bug description:
=============================================
SRU Justification
1. Impact: VMs fail to launch with TCG (non-kvm-accelerated)
2. Stable fix: cherrypick a patch from upstream.
3. Regression potential: this only slightly relaxes the check for multiple cpus, and is a cherrpyick from upstream. It therefore should not introduce any regressions.
4. Test case: See below - or simply attempt to launch a VM with multiple cpus on non-accelerated qemu.
=============================================
I'm testing the Kilo packages from the cloud archive staging PPA on
14.04 and cannot launch a VM due to a Libvirt CPU affinity error. I'm
using QEMU because my environment resides on cloud servers.
