其中: 资源池用于整合宿主机集群的物理资源，进而为虚拟机调度提供支持;

Among them: the resource pool is used to integrate the physical resources of the host cluster to provide support for virtual machine scheduling; a fixed number of frequent connections that can communicate with the host node are maintained in the connection pool; image management is used to add to the cloud storage layer Template image or delete virtual machine image or generate normal image based on template image cloning; Host cluster management performs heartbeat detection on the host node in the host cluster to ensure that the host node is available; Virtual machine scheduling is based on the resource pool. The virtual machine that needs to be turned on is scheduled to the appropriate host node.

Among them: the resource pool is used to integrate the physical resources of the host cluster, which in turn provides support for virtual machine scheduling. A fixed number of frequent connections in the connection pool that can communicate with host nodes; Mirror management is used to add template images to the cloud storage layer or to delete virtual machine images or to produce normal images based on template mirror clones; The host cluster management performs heartbeat detection on the host node in the host cluster to ensure that the host node is available. Virtual machine scheduling schedules virtual machines that need to be turned on to the appropriate host nodes, depending on the resource pool.

Among them: resource pool is used to integrate the physical resources of host cluster to provide support for virtual machine scheduling; connection pool maintains a fixed number of constant connections that can communicate with host nodes; image management is used to add template images to the cloud storage layer or delete virtual machine images or generate ordinary images according to template image clones; and; The host cluster management detects the heartbeat of the host nodes in the host cluster to ensure the availability of the host nodes; the virtual machine scheduling schedules the virtual machines that need to be turned on to the appropriate host nodes according to the situation of the resource pool.
