步骤S01，当需要向服务器200发送对虚拟机20进行管理的管理信号时，第一发送模块101通过网卡23向服务器200发一个询问命令，该询问命令用于请求服务器200在指定时间内通过网卡23发送回该询问命令对应的回应信息。 Step S01, when it is necessary to send a management signal to the server 200 to manage the virtual machine 20, the first sending module 101 sends an inquiry command to the server 200 through the network card 23, and the inquiry command is used to request the server 200 to pass the network card within a specified time. 23 Send back the response information corresponding to the inquiry command.
步骤S02，判断模块103判断第一接收模块102是否在该指定时间内接收到该回应信息，从而判断通过网卡23与服务器200进行数据传输的通道是否畅通。若第一接收模块102未在该指定时间内接收到该回应信息，则判断模块103判断通过网卡23与服务器200进行数据传输的通道不畅通，进入步骤S03，若第一接收模块102在该指定时间内接收到该回应信息，则判断模块103判断通过网卡23与服务器200进行数据传输的通道畅通，进入步骤S04。 Step S02 , the judging module 103 judges whether the first receiving module 102 receives the response message within the specified time, thereby judging whether the channel for data transmission between the network card 23 and the server 200 is unblocked. If the first receiving module 102 does not receive the response information within the specified time, then the judging module 103 judges that the channel for data transmission between the network card 23 and the server 200 is not smooth, and enters step S03. After receiving the response information within a certain time, the judging module 103 judges that the channel for data transmission with the server 200 through the network card 23 is unblocked, and enters step S04.
步骤S03，第二发送模块104将该管理信号发送至BMC22。BMC22接收到该管理信号后，将解析该管理信号是否含有所述标识信息，若该管理信号中含有该标识信息，则BMC22通过串口将该管理信号发送至虚拟机管理软件21。虚拟机管理软件21根据该管理信号执行虚拟机20的管理操作，并向管理主机100发送一个反馈信息，然后执行步骤S05。该反馈信息包括虚拟机20的管理操作是否执行成功，虚拟机20的IP地址、服务器200的IP地址等信息。 In step S03, the second sending module 104 sends the management signal to the BMC22. After receiving the management signal, the BMC22 will analyze whether the management signal contains the identification information. If the management signal contains the identification information, the BMC22 will send the management signal to the virtual machine management software 21 through the serial port. The virtual machine management software 21 executes the management operation of the virtual machine 20 according to the management signal, and sends a feedback message to the management host 100, and then executes step S05. The feedback information includes whether the management operation of the virtual machine 20 is successfully executed, the IP address of the virtual machine 20 , the IP address of the server 200 and other information.
具体而言，如果网卡23与服务器200进行数据传输的通道从不畅通变成畅通，则虚拟机管理软件21通过网卡23向管理主机100发送该反馈信息；如果网卡23与服务器200进行数据传输的通道仍然保持不畅通，则虚拟机管理软件21通过BMC22向管理主机100发送该反馈信息。 Specifically, if the channel for data transmission between the network card 23 and the server 200 changes from unblocked to unblocked, then the virtual machine management software 21 sends the feedback information to the management host 100 through the network card 23; If the channel is still blocked, the virtual machine management software 21 sends the feedback information to the management host 100 through the BMC22.
步骤S04，第二发送模块104将该管理信号发送至网卡23。网卡23接收到该管理信号后，将解析该管理信号是否含有所述标识信息，若该管理信号中含有该标识信息，则网卡23将该管理信号发送至虚拟机管理软件21。虚拟机管理软件21根据该管理信号执行虚拟机20的管理操作，并向管理主机100发送所述反馈信息，然后执行步骤S05。 Step S04 , the second sending module 104 sends the management signal to the network card 23 . After receiving the management signal, the network card 23 will analyze whether the management signal contains the identification information. If the management signal contains the identification information, the network card 23 will send the management signal to the virtual machine management software 21 . The virtual machine management software 21 executes the management operation of the virtual machine 20 according to the management signal, and sends the feedback information to the management host 100, and then performs step S05.
具体而言，如果网卡23与服务器200进行数据传输的通道从畅通变成不畅通，则虚拟机管理软件21通过BMC22向管理主机100发送该反馈信息；如果网卡23与服务器200进行数据传输的通道仍然保持畅通，则虚拟机管理软件21通过网卡23向管理主机100发送该反馈信息。 Specifically, if the channel for data transmission between the network card 23 and the server 200 changes from unblocked to unblocked, the virtual machine management software 21 sends the feedback information to the management host 100 through the BMC22; if the channel for data transmission between the network card 23 and the server 200 If it remains unblocked, the virtual machine management software 21 sends the feedback information to the management host 100 through the network card 23 .
步骤S05，第二接收模块105用于从服务器200接收虚拟机管理软件21发送的该反馈信息。 Step S05 , the second receiving module 105 is configured to receive the feedback information sent by the virtual machine management software 21 from the server 200 .
具体而言，如果网卡23与服务器200进行数据传输的通道一直保持畅通，或者从不畅通变成畅通，则第二接收模块105从网卡23接收虚拟机管理软件21发送的该反馈信息。如果网卡23与服务器200进行数据传输的通道一直保持不畅通，或者从畅通变成不畅通，则第二接收模块105从BMC22接收虚拟机管理软件21发送的该反馈信息。 Specifically, if the channel for data transmission between the network card 23 and the server 200 remains unblocked, or becomes unblocked from unblocked, the second receiving module 105 receives the feedback information sent by the virtual machine management software 21 from the network card 23 . If the channel for data transmission between the network card 23 and the server 200 remains unblocked, or changes from unblocked to unblocked, the second receiving module 105 receives the feedback information sent by the virtual machine management software 21 from the BMC 22 .
在其它实施例中，也可以设定如果第二发送模块104将该管理信号发送至BMC22，则不管网卡23与服务器200进行数据传输的通道是否畅通，第二接收模块105都从BMC22接收虚拟机管理软件21发送的该反馈信息。 In other embodiments, it can also be set that if the second sending module 104 sends the management signal to the BMC22, the second receiving module 105 will receive the virtual machine from the BMC22 no matter whether the data transmission channel between the network card 23 and the server 200 is unblocked or not. The feedback information sent by the management software 21.
