The rapid recovery method for a virtual machine -- -<K a comprises: pairing a first host machine with a second host machine to form a storage peer pair, and causing a read/write request on a virtual L machine of the first host machine to be backed up on the second host ma chine (S1); when the first host machine breaks down or is shut down, a - backup host machine starting the virtual machine of the first host machine I j I(S2); a virtual machine started on the backup host machine receiving a B read/write request sent by a caller, and determining whether full data syn a ,i h n DD chronization from the second host machine to the backup host machine is completed (S3); if not, sending the read/write request to the second host s 4>smT um~h ± s- machine, the second host machine receiving the read/write request, and storing, based on the read/write request and on the second host machine, data to be written, or obtaining specified data based on the read/write re quest and sending the specified data to the backup host machine (S4); and the backup host machine sending the specified data to the caller (S6).
