That is, the configuration file may reflect network configuration information of the network card, including related content that may reflect role information of the network card.
Specifically, it may be determined whether to set target gateway information in the configuration file of each network card according to the role information of each network card, for example, if the role information of the network card C is the first role, the target gateway information may be set in the configuration file of the network card C, and if the role information of the network card D is not the first role, the target gateway information is not set in the configuration file of the network card D.

S240, the network configuration information of the network card is fed back to the target computing resource through the DHCP server.
Specifically, the DHCP server determines, according to the configuration file, network configuration information of the network card to be fed back to the target computing resource. Namely, aiming at a certain network card, if the configuration file is provided with target gateway information, the network configuration information comprises the target gateway information; if the configuration file is not provided with the target gateway information, the network configuration information does not comprise the target gateway information.

Example III
Fig. 3 is a schematic diagram of an automatic default route configuration, which includes a computing management module, a network management module, a computing implementation module, a network address allocation module, a DHCP server, a virtual machine, and the like under an OpenStack platform.

Step A2: the Nova-api calculation management module requests the Neutron-server network management module to create a port (port) corresponding to the network card.
Step A3: and the Neutron-server network management module stores the network card (port) information into a database.
Step A4: the Neutron-server network management module requests configuration of the dhcp information from the Neutron-dhcp-agent network address allocation module through the RPC.
Step A5: and updating the dnsmasq configuration corresponding to the network card according to the role information of the network card by a neutron-DHCP-agent network address allocation module (the dnsmasq is a program for providing DNS caching and DHCP service functions, and the functions of a DHCP server can be realized).
Specifically, in the configuration file, if the network card role is dominant, the dhcp information of the IP is set to include a dhcp option 3. If the network card role is slave, the dhcp information of the IP is set to not contain dhcpoption.
And A6, calling a nova-computer calculation implementation module by using the nova-api calculation management module RPC to call the nova-computer calculation implementation module to hatch and create a virtual machine.
Step A7, the nova-computer computing implementation module creates a starting virtual machine.
Step A8, in the starting process of the virtual machine, the network cards respectively initiate a dhcp request,
Further, the dhcp message acquired by the network card with the main role contains the dhcp option 3 gateway information; the dhcp message acquired from the network card with the role does not contain the dhcp option information
And A9, the virtual machine sets the network card to have a default route when the gateway information of the dhcp option3 is contained according to the dhcp return message, and does not set the network card to have the default route when the option3 does not exist.
The technical scheme of the embodiment of the application can solve the problem of default route conflict of the virtual machine or the bare metal server in a multi-network card scene, does not limit an implemented operating system, and can be executed in windows, linux and other systems. In addition, any network card can be designated as a first role (main network card), flexibility is high, and the network card granularity is finer than the original network granularity due to the fact that default route conflict is avoided.
