Hi Rafael, in this case the hypervisor is KVM and I think it supports masking, but let me check if I got it right:
if the CPU is not exactly the same the features can be masked using hypervisor's capabilities. Does it mean that if the CPU has the exact same features but different frequency for example it would work?
