2287 * Make an asynchronous request for balloon info. When the request completes
2288 * a QDict will be returned according to the following specification:
2289 *
2290 * - "actual": current balloon value in bytes
2291 * The following fields may or may not be present:
2292 * - "mem_swapped_in": Amount of memory swapped in (bytes)
2293 * - "mem_swapped_out": Amount of memory swapped out (bytes)
2294 * - "major_page_faults": Number of major faults
2295 * - "minor_page_faults": Number of minor faults
2296 * - "free_mem": Total amount of free and unused memory (bytes)
2297 * - "total_mem": Total amount of available memory (bytes)
2298 *
2299 * Example:
2300 *
2301 * { "actual": 1073741824, "mem_swapped_in": 0, "mem_swapped_out": 0,
2302 * "major_page_faults": 142, "minor_page_faults": 239245,
