comparing whether the sequence number of the allocated idle logical core is consistent with the sequence number of the allocated idle logical core,
and if the virtual CPU distribution result is consistent with the virtual CPU distribution result, the virtual CPU distribution is completed.
8. An apparatus for creating a virtual machine and allocating a CPU resource, comprising:
the system comprises an acquisition module, a processing module and a control module, wherein the acquisition module is used for acquiring a configuration instruction of a user for creating a virtual machine, and the configuration instruction comprises the configuration number of virtual CPUs;
a creating module, configured to create a virtual machine according to the configuration instruction, so that the virtual machine includes the configured number of virtual CPUs, and allocate a corresponding physical CPU to each virtual CPU, where the physical CPU includes an idle logic core;
and the allocation module is used for allocating at least one idle logic core of the physical CPU to the corresponding virtual CPU.
9. A virtual machine creation and CPU resource allocation apparatus comprising a processor, a memory coupled to the processor, wherein,
the memory has stored therein computer readable instructions which, when executed by the processor, cause the processor to perform the steps of the virtual machine creation and CPU resource allocation method of any one of claims 1 to 7.
10. A storage medium storing computer readable instructions which, when executed by one or more processors, cause the one or more processors to perform the steps of the virtual machine creation and CPU resource allocation method of any one of claims 1 to 7.
