I agree with @daviftorres - UEFI is a must now. Just an important hint from operational experience - if live migrations are required now and in future, never use `guest.cpu.mode=host-passthrough` if you plan to update your hosts OS and kernel from time to time. Some bad suprises could arise breaking live migrations between identical hosts - some with newer kernel some with older kernel. Smooth rolling maintenance with live migrations will become impossible due to newer kernels suddenly supporting and detecting more performance counters on the identical CPU and not allowing live migrations between non-updated hosts and already updated hosts. Use `guest.cpu.mode=host-model` instead, even for identical hosts.
