Method for affinity binding of interrupt of virtual network interface card, and computer device

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.

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.
