Suleiman Souhlal 015c3c1eb9 x86_64: Introduce --no-smt flag. ... When set, VCPUs aren't presented to the guest as hyperthreads, on Intel. Instead, present them as different, non-hyperthreaded cores on the same package. Presenting them as hyperthreads might make the guest scheduler migrate tasks between VCPUs more aggressively, which can be expensive in a VM. AMD will need a different CL. BUG=b:169828263 TEST="cat /proc/sys/kernel/sched_domain/cpu0/domain0/name" in the guest returns "MC" instead of "SMT" when starting crosvm with --no-smt.
