Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0037] Currently, if a virtual CPU of a cloud host is bound to a physical CPU in a numa node, the cloud host can only use the virtual PCI device corresponding to the numa node. However, if all the virtual PCI devices corresponding to the numa node are used, then the current cloud host cannot be configured with available virtual PCI devices, which will cause the cloud host configuration to fail. For this reason, the present application provides a cloud host creation solution, which c...

Abstract

The invention discloses a cloud host creation method, apparatus and device, and a readable storage medium. The method disclosed by the invention comprises the following steps: if a creation request ofa target cloud host is received, creating the target cloud host, and binding a virtual CPU of the target cloud host with a physical CPU in a target numa node; if the virtual PCI device correspondingto the target numa node is not available and the target cloud host is configured with target metadata, configuring the virtual PCI devices corresponding to other numa nodes to the target cloud host, wherein the target metadata allows the physical CPU and the virtual PCI device bound with the target cloud host to correspond to different numa nodes, so that the virtual PCI device is configured for the cloud host when the numa node corresponding to the cloud host does not have the available virtual PCI device. Correspondingly, the cloud host creation device and equipment and the readable storagemedium provided by the invention also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, equipment and readable storage medium for creating a cloud host. Background technique [0002] Generally, a physical PCI (Peripheral Component Interconnect, peripheral component interconnection standard) device (such as a physical network card) on the host computer can be virtualized into multiple virtual PCI devices, and the physical CPU in the host computer can use NUMA (Non Uniform Memory Access Architecture (non-uniform memory access) technology is divided into multiple numa nodes, and each numa node includes at least one physical CPU (Central Processing Unit, central processing unit). Different numa nodes can correspond to different virtual PCI devices. In this way, if the virtual CPU of a cloud host is bound to the physical CPU in a numa node, the cloud host can only use the virtual PCI device corresponding to the numa node. . However, if...
