In the existing virtualization process of hardware resources, when scheduling the hardware resources, the following problems may occur:

when hardware resource scheduling is performed, existing SR-IOV-based I/O devices often only adopt "time" or "space", and these two methods perform resource scheduling at a larger granularity, where the "time" scheduling method is to schedule the same type of resource at different time periods, and the "space" scheduling method is to physically divide the resource into a plurality of sub-devices with the same function. However, these two resource scheduling methods are more suitable for hardware resources with single function, and when aiming at multi-functional hardware resources, they can only call the single function of the hardware resources, and cannot fully utilize each function included in the hardware resources, resulting in lower resource utilization rate of the multi-functional hardware resources.

In order to solve the above problem, the embodiments of the present disclosure provide a virtualization method, apparatus, and device based on SR-IOV. The following describes a resource scheduling method provided by the embodiment of the present disclosure with reference to fig. 1.

Claims

1. A SR-IOV based virtualization method is characterized by comprising the following steps:

acquiring resource scheduling requests of a plurality of tasks;

performing virtualization processing on the resources according to the scheduling request to obtain a plurality of virtualized resources;

allocating the plurality of virtualized resources to the plurality of tasks.

2. The method of claim 1, wherein before virtualizing the resources according to the scheduling request, the method comprises:

and determining the resources matched with the type of the task based on the type of the task.

3. The method according to claim 2, wherein the virtualizing resources according to the scheduling request comprises:

for the determined resources, determining the quantity of the resource virtualization according to the quantity of the tasks matched with the resources in the plurality of tasks;

virtualizing the resource to the number of virtualized resources.

4. The method of claim 3, wherein after determining the resource that matches the type of the task based on the type of the task, the method further comprises:

determining whether the resource is valid based on a target flag of the resource;

and when the resources are effective, determining the quantity of the resource virtualization according to the quantity of the tasks matched with the resources in the plurality of tasks for the determined resources.

5. An SR-IOV based virtualization management device, comprising:

the request acquisition module is used for acquiring resource scheduling requests of a plurality of tasks;

the resource virtualization module is used for performing virtualization processing on the resources according to the scheduling request to obtain a plurality of virtualized resources;

a resource allocation module to allocate the plurality of virtualized resources to the plurality of tasks.

6. The apparatus of claim 5, further comprising:

and the resource matching module is used for determining the resources matched with the types of the tasks based on the types of the tasks.

7. The apparatus of claim 6, wherein the resource virtualization module comprises:

a first resource quantity determining submodule, configured to determine, for the determined resource, a quantity of the resource virtualization according to the quantity of the tasks that are matched with the resource in the plurality of tasks;

a resource virtualization submodule, configured to virtualize the resource into the number of virtualized resources.

8. The apparatus of claim 7, further comprising:

the resource judging module is used for determining whether the resource is effective or not based on the target zone bit of the resource;

and the first resource quantity determining submodule is used for determining the quantity of the resource virtualization according to the quantity of the tasks matched with the resources in the plurality of tasks for the determined resources when the resources are effective.

9. An electronic device, comprising:

a processor;

a memory for storing executable instructions;

wherein the processor is configured to read the executable instructions from the memory and execute the executable instructions to implement the method of any of claims 1-4.

10. A computer-readable storage medium, characterized in that the storage medium stores a computer program which, when executed by a processor, causes the processor to carry out the method of any of the preceding claims 1-4.
