Tsirkin" , Marcelo Tosatti The STIBP flag may be supported by the host KVM module, so QEMU can allow it to be configured manually, and it can be exposed to guests when using "-cpu host". No additional migration code is required because the whole contents of spec_ctrl is already migrated in the "cpu/spec_ctrl" section.
