It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

The embodiment of the present invention provides a method for creating a virtual machine, as shown in Figure 1, the method includes:

Step 101, creating a new network interface.

Step 102, according to the information of the physical network card to be allocated to the virtual machine on the host, set the parameters of the network interface.

Specifically, the physical network card refers to a physical network card that is available on the host and is not allocated to the virtual machine.

Step 103, using the parameters of the network interface to create a virtual machine on the host.

When the host has enabled the hardware virtualization function, a virtual machine can be created on the host by using network interface parameters. Specifically, the parameters of the network interface are written into the configuration file of the virtual machine when the virtual machine is created.

For example, there are openstack and virtualization drivers on the host, and openstack creates a new network interface and sets the parameters of the network interface according to the information of the physical network card of the host. When a virtual machine needs to be created, openstack sends the parameters of the network interface to the virtualization driver, specifically , the data interaction between openstack and the virtualization driver is realized through the message forwarding mechanism, and the virtualization driver uses the parameters of the network interface to create a virtual machine on the host. In addition to sending the parameters of the network interface to the virtualization driver, openstack also sends other data required to create a virtual machine to the virtualization driver, such as the CPU (Central Processing Unit, central processing unit) information and Memory information. Among them, openstack is a free software and open source project authorized by the Apache license, jointly developed and initiated by NASA (National Aeronautics and Space Administration, National Aeronautics and Space Administration) and Rackspace.

If the number of network interfaces is two or more, the network interface used for creating the virtual machine is selected from the two or more network interfaces according to the names of the network interfaces.

After the host creates a network interface, the host stores the created network interface in the database. If there are more than one network interface stored in the database, the name of each network interface is different. Therefore, when creating a virtual machine, according to The name of the network interface selects the network interface used to create the virtual machine from multiple network interfaces.

Further, the parameters of the network interface include one or any combination of the following: type of network card, ID of a physical network card, Internet Protocol (IP) address for interconnection between networks, and Media Access Control (MAC) address.

For example, the parameter of the network interface is binding:profile, and the binding:profile includes {'vnic-type':'direct-physical','net-id':'netId'}, where 'vnic-type' indicates the network card type, 'direct-physical' indicates the value corresponding to the network card type, 'net-id' indicates the ID of the physical network card, and netId' indicates the value corresponding to the ID of the physical network card.
