In the embodiment of the invention, after the corresponding virtual machine is started, the service node receives the discovery message sent by the virtual machine which is forwarded to the logic service process by the virtual switch.

In the embodiment of the invention, after the virtual machine is started, the virtual switch broadcasts the discovery message, and the virtual switch forwards the discovery message to the logic service process of the corresponding service node. Wherein the virtual machine is pre-bound with the service node. The logical service process is pre-built.

In the embodiment of the invention, the service node is one service node in a cloud server in a cloud network environment. The cloud server can comprise a plurality of service nodes, and each service node can be correspondingly bound with one virtual machine. The service node may be a host or a terminal in the cloud server, where a logical service process is built on each host.

The embodiment of the invention provides a distributed dhcp scheme based on a virtual machine, and by way of example, referring to fig. 2, the overall structure of the cloud server of the invention relates to the components of the virtual machine 104, the interface 102, the virtual switch 101, the message middleware 100 and the like. The cloud server calculates service nodes to which the ip information is to be distributed by using an algorithm, and distributes the user configuration ip information to the designated service nodes through the message middleware 100. When the virtual machine 104 sends a dhcp request message, the virtual switch 101 of the corresponding service node intercepts the dhcp message, converts the user configuration ip into a dhcp response packet message, sends the dhcp response packet message to the virtual machine 104, and the virtual machine 104 writes the dhcp response packet into the network card according to the dhcp message.

Wherein the discovery message is a dhcp discover discovery message.

In the embodiment of the invention, a service node responds to a discovery message, and a logic service process sends preset configuration address information to a virtual machine according to a preset program so that the virtual machine can write the configuration address information into a virtual network card; the configuration address information is calculated by the server according to a plurality of configuration address information acquired in advance and the relevant information and the local storage position of the virtual machine corresponding to the plurality of configuration address information respectively, and then the configuration address information is configured to the local.

Wherein the related information includes: operation location information and operation policy information.

In the embodiment of the invention, the service node responds to the discovery message, feeds back a notification confirmation message to the virtual machine through the logic service process, receives the request message of the virtual machine, converts the configuration address information into a response message according to the preset program by the logic service process of the service node, and sends the response message to the virtual machine for the virtual machine to write in the virtual network card. The notification confirmation message is a dhcp offer message, and the request message is a dh cp request message.

In the embodiment of the invention, the cloud server firstly receives a plurality of configuration address information sent by a plurality of user nodes. The plurality of matching address information corresponds to the plurality of virtual machines. And the cloud server calculates according to the related information of the plurality of virtual machines and the storage positions of the plurality of service nodes, and respectively configures the plurality of configuration address information to the corresponding service nodes. In an exemplary embodiment of the present invention, the cloud server may perform calculation by using an IP address allocation method, so as to respectively configure a plurality of configuration address information to corresponding service nodes.

In the embodiment of the invention, the user node sends the ipv4/ipv6 information configured by the user to the vm port (which is an interface through which data is transferred between the computer and other devices, between networks or between other directly connected computers) through the message middleware. After the virtual machine is started, a dhcp discover message is sent in a broadcast mode to search for a dhcp server (i.e. a service node). The cloud server builds a logical dhcp server process on each service node. The vm port forwards the dhcp discover message to the dhcp server process of the current host, and the dhcp server process sends the dhcp refer message containing the ip configured at the port by the user and other settings to the virtual machine. vm accepts the first received dhcp offer message and then it responds in broadcast fashion to a dhcp request message containing the contents of the address requested for its selected vm port, and when vm port dhcp server receives the dhcp request message answered by the virtual machine, a dhcp acknowledgement is sent to vm containing the ip address it provides and other settings telling the virtual machine that it can use the ip address it provides, and then the virtual machine binds its tcp/ip protocol to the network card.

In the embodiment of the invention, when a user newly builds a virtual machine, the user can configure the Internet protocol version 4 (Internet Protocol version, IPv 4)/Internet protocol version 6 (Internet Protocol version, IPv 6) on the configuration item of the virtual machine without concern about the operating system of the virtual machine, the storage position of the virtual machine or the running position of the virtual machine, and entering the acquisition duid, and after the operating system is installed in the virtual machine and the virtual switch is connected, the virtual machine can acquire the configured ip information. For example, when a user node newly adds a virtual machine, in conjunction with fig. 3, a user may configure a physical (Media Access Control or Medium Access Control, MAC) address at the newly added virtual machine configuration interface of the user node, and when an IPv4 address is used, an IP address, a subnet mask, a gateway, a preferred domain name system (Domain Name System, DNS), and an alternative DNS may be configured. In connection with fig. 4, a user may configure a MAC address in a newly added virtual machine configuration interface of a user node, and may configure an IP address, a prefix length, a gateway, a preferred domain name system DNS, and an alternative DNS when using an IPv6 address.

In the embodiment of the invention, when a user edits the virtual machine, the user does not need to care about an operating system of the virtual machine, does not need to care about a storage position of the virtual machine, does not need to care about an operation position of the virtual machine and does not need to care about dhcp lease time, the ipv4/ipv6 can be updated to the configuration of the virtual machine, and if the virtual machine is in a shutdown state, the virtual machine is connected with a virtual switch after being started, and the virtual machine can be updated to new ip information. For example, when a user newly adds a virtual machine, in conjunction with fig. 5, the user may configure an IP address, a subnet mask, a gateway, a preferred domain name system DNS, and an alternative DNS when configuring an IPv4 address in a modified IP setting control of an edit virtual machine configuration interface of a user node. In connection with fig. 6, a user may configure an IP address, a prefix length, a gateway, a preferred domain name system DNS, and an alternative DNS when configuring an IPv6 address in a modified IP settings control of an edit virtual machine configuration interface of a user node.
