From: Tom Lendacky<thomas.lendacky@xxxxxxx> Currently, the nested state format is hardcoded to VMX. This will result in kvm_put_nested_state() returning an error because the KVM SVM support checks for the nested state to be KVM_STATE_NESTED_FORMAT_SVM. As a result, kvm_arch_put_registers() errors out early. Update the setting of the format based on the virtualization feature: VMX - KVM_STATE_NESTED_FORMAT_VMX SVM - KVM_STATE_NESTED_FORMAT_SVM
Looks good, but what are the symptoms of this in practice? Paolo
