US 2019/0155637 A1 · Resource Access Method Applied to Computer and Computer

Abstract

A resource access method applied to a computer and the computer, where the resource access method is performed by a resource controller which is used to implement resource virtualization. The method includes receiving a resource access request of a virtual machine (VM) for a resource, where the resource access request carries a resource virtual address and an identifier of the VM, translating the resource virtual address into a resource physical address using the identifier of the VM and based on a preset resource information mapping relationship, updating the resource virtual address in the resource access request using the resource physical address, and sending an updated resource access request to a to-be-accessed resource corresponding to the resource physical address in order to access the to-be-accessed resource.

Dependent claims

A resource access method, the resource access method being applied to a computer comprising a resource and a resource controller, and the resource access method comprising:

receiving, by the resource controller, a resource access request of a virtual machine for the resource, the resource access request carrying a resource virtual address and an identifier of the virtual machine, and the virtual machine running on the computer;
translating, by the resource controller, the resource virtual address into a resource physical address using the identifier of the virtual machine and based on a resource information mapping relationship;
updating, by the resource controller, the resource virtual address in the resource access request using the resource physical address;
and
sending, by the resource controller, an updated resource access request to a to-be-accessed resource corresponding to the resource physical address in order to access the to-be-accessed resource.

2 more elements

A computer, comprising:

a resource;
a resource controller coupled to the resource;
and
a resource manager coupled to the resource and the resource controller and configured to:
select a physical resource from the resource;
create a virtual machine based on the selected physical resource;
allocate an identifier to the virtual machine;
generate, based on the identifier of the virtual machine and attribute information of the selected physical resource, a resource information mapping relationship;
and
send the resource information mapping relationship to the resource controller, and the resource controller being configured to:
receive a resource access request of the virtual machine for the resource, the resource access request carrying a resource virtual address and the identifier of the virtual machine;
translate the resource virtual address into a resource physical address using the identifier of the virtual machine and based on the resource information mapping relationship;
update the resource virtual address in the resource access request using the resource physical address;
and
send an updated resource access request to a to-be-accessed resource corresponding to the resource physical address in order to access the to-be-accessed resource.
