Hi Eduardo， After kvm use "-overcommit cpu-pm=on" to expose MONITOR/MWAIT(commit id 6f131f13e68d648a8e4f083c667ab1acd88ce4cd), the MONITOR/MWAIT feature in CPU model (phenom core2duo coreduo n270 Opteron_G3 EPYC Snowridge Denverton) may be unused. For example, when we boot a guest with Denverton cpu model, guest cannot detect MONITOR and boot with no warning. Should we remove this feature from some CPU model?
