Abstract

The embodiment of the invention provides a virtual machine creating method and system and a host. Each host identity in a binding relationship between tenant identities and host identities only corresponds to one tenant identity; for any one tenant having a physical isolation requirement on the host, the virtual machine creating system can only create a virtual machine of the tenant in the host having the host identity corresponding to the tenant identity of the tenant but cannot create the virtual machine of the tenant in the hosts having the host identities corresponding to the tenant identities of other tenants, that is to say, the host having the host identity corresponding to the tenant identity of the tenant can only contain the virtual machine of the tenant but cannot contain the virtual machines of the other tenants; therefore, physical isolation among the virtual machines of different tenants is achieved, and then the data security among the virtual machines of different tenants is improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a virtual machine creation method, system and host. Background technique [0002] Currently, in the field of public cloud, ordinary IaaS (Infrastructure as a Service, Infrastructure as a Service) realizes the isolation between computing resources of multiple tenants in a virtualized way. This way realizes the creation of different tenants on the same server. For virtual machines, this isolation is essentially a logical isolation, and different tenants do not monopolize their own physical resources. For example, different virtual machines on a physical machine may belong to different tenants. [0003] However, when multiple different virtual machines on a server belong to different tenants, the virtual machines of different tenants share hardware resources such as memory and CPU of the same server, and a virtual machine of one tenant can steal othe...
