When PAGE_SIZE > HV_HYP_PAGE_SIZE, we need the ringbuffer size to be at least 2 * PAGE_SIZE: one page for the header and at least one page of the data part (because of the alignment requirement for double mapping). So make sure the ringbuffer sizes to be at least 2 * PAGE_SIZE when using vmbus_open() to establish the vmbus connection.
