Configuration of speed of virtual network interface card

A machine device, comprising a storage medium, a processor, and machine executable instructions that are stored on the storage medium and can be run on the processor, wherein the processor executes the machine executable instructions to implement the following operations, comprising:

• after a virtual machine (VM) is started, configuring an initial transmission speed of a virtual network interface card (NIC) in the VM by using an internal interface set in the VM, and saving the initial transmission speed in the virtual NIC, wherein the internal interface is used to configure a transmission speed of the virtual NIC and allow communication with an external interface of a physical machine;
• and
• during the running of the VM, if the transmission speed of the virtual NIC needs to be modified,
• invoking the external interface to obtain a target transmission speed, and
• reconfiguring the target transmission speed as the transmission speed of the virtual NIC via the internal interface.

A non-volatile machine readable storage medium, storing machine executable instructions, wherein the machine executable instructions are executed by a processor to implement the following operations, comprising:

• after a virtual machine (VM) is started, configuring an initial transmission speed of a virtual network interface card (NIC) in the VM by using an internal interface set in the VM, and saving the initial transmission speed in the virtual NIC, wherein the internal interface is used to configure a transmission speed of the virtual NIC and allow communication with an external interface of a physical machine;
• and
• during the running of the VM, if the transmission speed of the virtual NIC needs to be modified,
• invoking the external interface to obtain a target transmission speed, and
• reconfiguring the target transmission speed as the transmission speed of the virtual NIC via the internal interface.
