virDomainReboot takes a flag argument which is documented as: * @flags: extra flags for the reboot operation, not used yet In fact, the test driver (alone) allows a virDomainRestart typedef to be passed as a flag, although it's not clear to me that anything actually does pass it. Certainly removing virDomainRestart typedef from <libvirt.h> doesn't break the build, and 'make check' is also OK. The attached patch moves virDomainRestart typedef into the test driver, which is the only thing using it. Another possibility would be to go further and remove the parts of the test driver which "test" this undocumented feature. (Thanks to Tóth István for pointing out that this typedef is unused).
