I find when do the migration,nova detect that two host have different CPU flags(cat /proc/cpuinfo),and it will rise "InvalidCPUInfo: Unacceptable CPU info: CPU doesn't have compatibility" If you want to solve this problem, better to choose hosts within same CPU or try to change the code in this section.
