Virtual Machine Resource Allocation Method and Apparatus

A virtual machine resource allocation apparatus, comprising:

• a first physical processor;
• a first physical memory coupled to the first physical processor;
• and
• a first physical input/output (IO) device coupled to the first physical processor,
• wherein the first physical processor is configured to:
• acquire a resource allocation parameter of a virtual machine using the first physical IO device, wherein the resource allocation parameter comprises a scheduling parameter indicating that at least two of a second physical processor, a second physical memory, and a second physical IO device allocated to the virtual machine are located on a same processor node;
• and
• allocate a physical resource to the virtual machine according to the resource allocation parameter.
