Instead, clear PID.SN > right before VM-entry and set it after VM-exit. One correction here. My comment in v1 [1] was actually close to Sean's suggestion, i.e. opposite to above description: -- I wonder whether it makes more sense to have 'sn' closely sync-ed with vcpu->mode, e.g. having a kvm_x86_set_vcpu_mode() ops to translate vcpu->mode into vmx/svm specific hardware bits like 'sn' here. Then call it in common place when vcpu->mode is changed. -- [1] https://lore.kernel.org/lkml/BN9PR11MB52766B74ADFBAEC0AA205E298CB39@BN9= PR11MB5276.namprd11.prod.outlook.com/
