Ok. So if I wanted to have reliable live migration on my Icehouse cluster, would this be a valid approach?
1) Find lowest common denominator CPU model across all hypervisors using virsh capabilities / virsh cpu-baseline
2) Configure nova-compute.conf to include cpu_mode=custom, cpu_model=Westmere (in my case)
3) Disable the CPU check in nova/virt/libvirt/driver.py (comment out line 4248)
4246 # Compare CPU
4247 source_cpu_info = src_compute_info['cpu_info']
4248 self._compare_cpu(source_cpu_info)Assuming this cluster is not going to get any older CPU or non-Intel CPU models in the future, this should be safe, right?
