obtaining, from a management device based on the first identifier, the second identifier; and

sending the probe packet through a second tunnel port of the destination device.

5. The virtual machine status probe method of claim 1 , wherein before obtaining the invocation message, the virtual machine status probe method further comprises sending a first message to a server, and wherein the first message requests disk storage information of the first virtual machine in the server and determines the status of the first virtual machine based on a storage plane of the first virtual machine.

6. The virtual machine status probe method of claim 1 , further comprising:

determining not to recreate the first virtual machine in the destination device when the feedback information indicates that the status of the first virtual machine in the source device is normal; or

determining to recreate the first virtual machine in the destination device when the feedback information indicates that the status of the first virtual machine in the source device is faulty.

7. The virtual machine status probe method of claim 1 , wherein the broadcast packet comprises includes a destination media access control (MAC) address and a source MAC address.

8. A destination device, comprising:

a processor; and

a memory coupled to the processor and configured to store instructions that, when executed by the processor, cause the destination device to be configured to:

obtain an invocation message and a first identifier of a probe virtual local area network (VLAN) first service plane in which a virtual machine is located;

invoke a probe script based on the invocation message;

transfer the first identifier to the probe script;

send a probe packet by running the probe script, wherein the probe packet probes a status of the first virtual machine in a source device, and wherein the probe packet is a broadcast packet when a first probe port of the source device and a second probe port of the destination device are located in a same VLAN, and wherein the probe packet comprises the probe VLAN identifier;

receive feedback information from the source device in response to the probe packet, wherein the feedback information indicates the status of the first virtual machine; and

determine, based on the feedback information, whether to recreate the first virtual machine in the destination device.

9. The destination device of claim 8 , wherein the instructions further cause the destination device to be configured to:

receive the probe VLAN identifier from a management device;

configure the second probe port in the first service plane;

configure the probe VLAN identifier for the second probe port; and

send the probe packet through the second probe port.

10. The destination device of claim 8 , wherein the probe packet is a unicast packet when the source device communicates with the destination device through an overlay network, and wherein the probe packet comprises a second identifier of a first tunnel port of the source device.

11. The destination device of claim 10 , wherein the instructions further cause the destination device to be configured to:

obtain, from a management device based on the first identifier, the second identifier; and

send the probe packet through a second tunnel port of the destination device.

12. The destination device of claim 8 , wherein the instructions further cause the destination device to be configured to send a first message to a server, and wherein the first message requests disk storage information of the first virtual machine in the server and determines the status of the first virtual machine based on a storage plane of the first virtual machine.

13. The destination device of claim 8 , wherein the instructions further cause the destination device to be configured to:

determine not to recreate the first virtual machine in the destination device when the feedback information indicates that the status of the first virtual machine in the source device is normal; or

determine to recreate the first virtual machine in the destination device when the feedback information indicates that the status of the first virtual machine in the source device is faulty.

14. The destination device of claim 8 , wherein the broadcast packet comprises includes a destination media access control (MAC) address and a source MAC address.

15. A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a destination device to:

obtain an invocation message and a probe virtual local area network (VLAN) identifier of a first service plane in which a first virtual machine is located;

invoke a probe script based on the invocation message;

transfer the first identifier to the probe script;

send a probe packet by running the probe script, wherein the probe packet probes a status of the first virtual machine in a source device, wherein the probe packet is a broadcast packet when a first probe port of the source device and a second probe port of the destination device are located in a same VLAN, and wherein the probe packet comprises the probe VLAN identifier;

receive feedback information from the source device in response to the probe packet, wherein the feedback information indicates the status of the first virtual machine; and

determine, based on the feedback information, whether to recreate the first virtual machine in the destination device.

16. The computer program product of claim 15 , wherein the instructions further cause the destination device to:

receive the probe VLAN identifier from a management device;

configure the second probe port in the first service plane;
