Hi Shaoqin, I think you can add compat option in hw_compat_10_0. Then the compat property will be applied for v10.0 and before. And you can find v10.1 won't be affected by compat option you set. You can test this with "-machine pc-q35-10.0" or older, with "-machine pc-q35" or "-machine pc-q35-10.1". > I think it should have the hw_compat_10_1 first, then I can add the property > into it. This hw_compat_10_1 will be added when v10.1 is realeased. Thanks, Zhao
