Abstract: This application provides example optical communications apparatuses. One example optical communications apparatus includes a control apparatus and an optical module matching apparatus. The control apparatus can output a first control signal to the control end. An input end of the optical module matching apparatus can connect to a first optical module and receive a first electrical signal output by the first optical module. An output end of the optical module matching apparatus can output a first serial signal. The control apparatus can output a second control signal to the control end. The input end of the optical module matching apparatus can receive a second electrical signal output by the second optical module. The output end of the optical module matching apparatus can output a second serial signal. The first electrical signal and the second electrical signal can have different level types.

Abstract: A virtual machine recovery method, where after receiving a virtual machine recovery command for recovering a to-be-recovered virtual machine, a virtual machine management device obtains configuration information of the to-be-recovered virtual machine from a cloud server. Then the virtual machine management device creates, according to the configuration information, a recovered virtual machine and a local storage. After downloading basic system data from the cloud server, the recovered virtual machine is started according to the basic system data. When receiving an input/output (IO) request for accessing a first data of the to-be-recovered virtual machine, the virtual machine management device downloads the first data from the cloud server to the local storage. Hence, virtual machine recovery efficiency can be improved.
