The computer device may be formed by integrating a software defined network controller (SDN controller for short) and a device management service, after receiving a request for creating a bare metal server, the SDN controller may create configuration information of a virtual network card, then put the configuration information of the virtual network card into a message queue, the device management service periodically obtains the configuration information of the virtual network card from the message queue, and then call a physical switch according to the configuration information of the virtual network card, create a virtual bare metal gateway, deploy the bare metal server to the first network, and construct a virtual network card table of the virtual network card in the virtual bare metal gateway. Optionally, in practical application, the SDN controller may directly send the configuration information of the virtual network card to the device management service, without going through a message queue.

For example, after the virtual bare metal gateway creates the virtual machine interface, an agent program running on the virtual bare metal gateway initiates subscription to the SDN controller through an XMPP protocol, the SDN controller issues virtual routing forwarding information VRF, IP address, MAC address, routing table and other virtual bare metal gateway information of the virtual network card, and the computer device can obtain relevant information of the virtual network card.

And S503, updating the route information in the route forwarding table according to the related information of the virtual network card to obtain the configured virtual bare metal gateway.

In the embodiment of the application, after the computer equipment obtains the relevant information of the virtual network card based on the steps, the routing information in the routing forwarding table can be updated according to the relevant information of the virtual network card so as to obtain the configured virtual bare metal gateway, for example, after receiving the relevant information of the virtual network card issued by the SDN controller, the agent program can perform format conversion on the virtual bare metal gateway information, then store the information after format conversion into a self memory data structure, and issue information such as a VRF table, a routing table, a vxlan, a vlan and the like to a forwarding surface (the forwarding surface supports DPDK high-speed forwarding) for forwarding, and in the subsequent process of deploying an operating system, deployment can be realized through the virtual bare metal gateway.
