A virtual machine status probe method in a system comprising a destination device having a probe port; and a source device having a probe port and running a first virtual machine, wherein the first virtual machine is located in a first service plane; wherein the probe port of the source device and the probe port of the destination device are located in a same VLAN; a management device storing a probe virtual local area network VLAN identifier of the service plane in which the first virtual machine is located; wherein the method is performed by the destination device, and comprises: when a high availability procedure of the first virtual machine is triggered, obtaining, from the management device an invocation message comprising an identifier of the first virtual machine and the probe virtual local area network VLAN identifier of the first service plane; configuring the probe port of the destination device in the first service plane, and configuring the probe virtual VLAN identifier for the probe port of the destination device; sending a probe packet through the probe port of the destination device to the source device, wherein the probe packet is used to probe a status of the first virtual machine in the source device, the probe packet is a broadcast packet, and the probe packet comprises the obtained identifier of the first virtual machine and the obtained identifier of the probe VLAN; receiving feedback information sent by the source device, wherein the feedback information is used to indicate the status of the first virtual machine; and determining, based on the feedback information, whether to recreate the first virtual machine in the destination device. a destination device having a probe port; and a source device having a probe port and running a first virtual machine, wherein the first virtual machine is located in a first service plane; wherein the probe port of the source device and the probe port of the destination device are located in a same VLAN; a management device storing a probe virtual local area network VLAN identifier of the service plane in which the first virtual machine is located; wherein the method is performed by the destination device, and comprises: when a high availability procedure of the first virtual machine is triggered, obtaining, from the management device an invocation message comprising an identifier of the first virtual machine and the probe virtual local area network VLAN identifier of the first service plane; configuring the probe port of the destination device in the first service plane, and configuring the probe virtual VLAN identifier for the probe port of the destination device; sending a probe packet through the probe port of the destination device to the source device, wherein the probe packet is used to probe a status of the first virtual machine in the source device, the probe packet is a broadcast packet, and the probe packet comprises the obtained identifier of the first virtual machine and the obtained identifier of the probe VLAN; receiving feedback information sent by the source device, wherein the feedback information is used to indicate the status of the first virtual machine; and determining, based on the feedback information, whether to recreate the first virtual machine in the destination device. when a high availability procedure of the first virtual machine is triggered, obtaining, from the management device an invocation message comprising an identifier of the first virtual machine and the probe virtual local area network VLAN identifier of the first service plane; configuring the probe port of the destination device in the first service plane, and configuring the probe virtual VLAN identifier for the probe port of the destination device; sending a probe packet through the probe port of the destination device to the source device, wherein the probe packet is used to probe a status of the first virtual machine in the source device, the probe packet is a broadcast packet, and the probe packet comprises the obtained identifier of the first virtual machine and the obtained identifier of the probe VLAN; receiving feedback information sent by the source device, wherein the feedback information is used to indicate the status of the first virtual machine; and determining, based on the feedback information, whether to recreate the first virtual machine in the destination device.
