Abstract

The present invention discloses a method for affinity binding of interrupt of a virtual network interface card, and a computer device. The method includes: receiving a request message sent by an IaaS resource management system, where the request message carries an interrupt affinity policy parameter of a virtual network interface card; performing one-to-one correspondence affinity binding between multiple virtual central processing units VCPUs and multiple physical central processing units PCPUs; performing affinity binding between a virtual interrupt of the virtual network interface card and a VCPU; and performing affinity binding between a physical interrupt of the virtual network interface card and a corresponding PCPU according to the affinity policy parameter.

First claim

What is claimed is:

1. A method for affinity binding of an interrupt of a virtual network interface card, wherein the method comprises:
receiving, by a computer device, a request message from an Infrastructure as a Service (IaaS) resource management system, wherein the request message carries an interrupt affinity policy parameter of the virtual network interface card;
enabling a capturing module included in a host operating system executed by the computer device based on the interrupt affinity policy parameter, wherein the capturing module is configured to, when enabled, capture an operation executed by a guest operating system of a virtual machine for performing an affinity binding of a virtual interrupt of the virtual network interface card and a first virtual central processing unit (CPU);
performing, by the computer device and in response to the capturing module being enabled, affinity binding between a physical interrupt of the virtual network interface card and a first physical CPU, wherein the first virtual CPU is in affinity binding with the first physical CPU;
processing interrupts of the virtual network interface card; and
performing affinity binding between the physical interrupt of the virtual network interface card and a second physical CPU in response to the capturing module detecting the virtual interrupt of the virtual network interface card changing to be in affinity binding with a second virtual CPU, wherein the second virtual CPU is in affinity binding with the second physical CPU.

2. The method according to claim 1 , wherein performing the affinity binding between the physical interrupt of the virtual network interface card and the first physical CPU further comprises:
finding a corresponding physical interrupt number according to a virtual interrupt number of the virtual network interface card; and
determining the first physical CPU according to the affinity binding between the first virtual CPU and the first physical CPU.

3. The method according to claim 1 , wherein performing the affinity binding between the physical interrupt of the virtual network interface card and the second physical CPU further comprises:
finding a corresponding physical interrupt number according to a virtual interrupt number of the virtual network interface card; and
determining the second physical CPU according to the affinity binding between the second virtual CPU and the second physical CPU.

4. A computer device comprising:
a non-transitory memory comprising processor-executable instructions; and
one or more processors in communication with the memory, wherein the one or more processors are configured to execute the processor-executable instructions to facilitate:
receiving a request message from an Infrastructure as a Service (IaaS) resource management system, wherein the request message carries an interrupt affinity policy parameter of a virtual network interface card;
enabling a capturing module included in a host operating system based on the interrupt affinity policy parameter, wherein the capturing module is configured to, when enabled, capture an operation executed by a guest operating system of a virtual machine for performing an affinity binding of a virtual interrupt of the virtual network interface card and a first virtual central processing unit (CPU);
performing affinity binding between a physical interrupt of the virtual network interface card and a first physical CPU in response to the capturing module being enabled, wherein the first virtual CPU is in affinity binding with the first physical CPU;
processing interrupts of the virtual network interface card; and
performing affinity binding between the physical interrupt of the virtual network interface card and a second physical CPU in response to the capturing module detecting the virtual interrupt of the virtual network interface card changing to be in affinity binding with a second virtual CPU, wherein the second virtual CPU is in affinity binding with the second physical CPU.

5. The computer device according to claim 4 , wherein the one or more processors are further configured to execute the processor-executable instructions to facilitate:
capturing, when the capturing module is enabled, an operation of performing affinity binding between the virtual interrupt of the virtual network interface card and one of multiple virtual CPUs.

6. A non-transitory memory storage comprising processor-executable instructions, that when executed by a processor, cause the processor to facilitate:
receiving a request message from an Infrastructure as a Service (IaaS) resource management system, wherein the request message carries an interrupt affinity policy parameter of a virtual network interface card;
enabling a capturing module included in a host operating system based on the interrupt affinity policy parameter, wherein the capturing module is configured to, when enabled, capture an operation executed by a quest operating system of a virtual machine for performing an affinity binding of a virtual interrupt of the virtual network interface card and a first virtual central processing unit (CPU);
performing affinity binding between a physical interrupt of the virtual network interface card and a first physical CPU in response to the capturing module being enabled, wherein the first virtual CPU is in affinity binding with the first physical CPU;
processing interrupts of the virtual network interface card; and
performing affinity binding between the physical interrupt of the virtual network interface card and a second physical CPU in response to the capturing module detecting the virtual interrupt of the virtual network interface card changing to be in affinity binding with a second virtual CPU, wherein the second virtual CPU is in affinity binding with the second physical CPU.

7. The non-transitory memory according to claim 6 , wherein the processor-executable instructions further include instructions for a processor to facilitate:
capturing, when the capturing module is enabled, an operation of performing affinity binding between the virtual interrupt of the virtual network interface card and one of multiple virtual CPUs.
