Abstract

A resource configuration method of a virtual machine and a communications device. When an actual requirement of the virtual machine for the network resource is dynamically changed, the communications device may dynamically configure a communication manner corresponding to the virtual machine such that a virtual machine with a relatively low requirement for the network resource may use the manner of sharing the physical network interface card, and a virtual machine with a relatively high requirement for the network resource may use the pass-through manner, which does not cause a situation in which network resources of some virtual machines are wasted and network resources of some virtual machines are insufficient. As a result, network resources of virtual machines are properly allocated.

First claim

dynamically configuring at least one second virtual machine of the plurality of virtual machines to share a second physical network interface card of the plurality of physical network interface cards, wherein a requirement indication information of the at least one second virtual machine does not meet the preset pass-through condition, wherein configuring the at least one second virtual machine to share the second physical network interface card comprises:
selecting a physical network interface card of the plurality of physical network interface cards whose network traffic or load is less than or equal to a preset value to perform sharing as the second physical network interface card; and
changing a hardware network resource in a configuration file of the at least one second virtual machine to a resource of the shared second physical network interface card.

setting an initial value of the requirement indication information corresponding to each virtual machine of the plurality of virtual machines;
configuring a virtual machine whose initial value of the requirement indication information meets the preset pass-through condition to communicate in a pass-through manner; and
configuring a virtual machine whose initial value of the requirement indication information does not meet the preset pass-through condition to share a physical network interface card.

7. A communications device for resource configuration of one or more virtual machines, comprising:
multiple physical network interface cards;
multiple virtual machines;
a memory; and
a processor, wherein the memory storing instructions which, when executed by the processor, cause the processor to be configured to:
dynamically acquire requirement indication information of the multiple virtual machines for a network resource;
dynamically configure at least one first virtual machine of the multiple virtual machines to communicate using a first physical network interface card of the multiple physical network interface cards in a pass-through manner, wherein a requirement indication information of the at least one first virtual machine meets a preset pass-through condition; and
dynamically configure at least one second virtual machine of the multiple virtual machines to share a second physical network interface card of the multiple physical network interface cards, wherein a requirement indication information of the at least one second virtual machine does not meet the preset pass-through, wherein configuring the at least one second virtual machine to share the second physical network interface card comprises:
selecting a physical network interface card of the multiple physical network interface cards whose network traffic or load is less than or equal to a preset value to perform sharing as the second physical network interface card; and
changing a hardware network resource in a configuration file of the at least one second virtual machine to a resource of the shared second physical network interface card.

8. The communications device according to claim 7 , wherein the instructions further cause the processor to be configured to acquire network traffic or load of the multiple virtual machines, and wherein the preset pass-through condition comprises network traffic or the load is greater than a first threshold, wherein the network traffic or load of the at least one first virtual machine is greater than the first threshold.

9. The communications device according to claim 7 , wherein the instructions further cause the processor to be configured to:
acquire the network traffic or load of each virtual machine of the multiple virtual machines, wherein the at least one first virtual machine comprises N virtual machines whose network traffic or load ranks ahead, and wherein N is less than a quantity of physical network interface cards.
