We do parse and represent period collection as unsigned int in our internal structures, however commit d5c67e7f4523450023b89b69c16472582c85eeaf converts this to int, thus wrapping around inputs greater than INT_MAX which results in an error from QEMU. This patch adds a check into QEMU driver, because period attribute is only supported by QEMU.
