A virtualization management method is disclosed. The method includes: A virtual network function manager (VNFM) receives a first instantiation request message of a virtual network function (VNF) sent by a service orchestrator (SO) or a network functions virtualization orchestrator (NFVO), where the first instantiation request message includes a VNF identifier and virtualised infrastructure manager (VIM) information, and the VIM information includes a VIM type and a supported template language. The VNFM obtains a VNF package based on the VNF identifier. When determining that the supported template language of the VIM information is a first template language, the VNFM obtains first VNF sub-information that is consistent with the first template language from template information, where the first VNF sub-information is used to deploy the VNF. The template information is included in a virtual network function descriptor (VNFD) of the VNF package. The VNFM sends the first VNF sub-information to a multi-cloud platform, so that the multi-cloud platform deploys the VNF on a corresponding VIM.
