摘要： A system that includes multiple hosts, each having physical resources, a hypervisor, and a host agent that causes the virtual machines to operate above the hypervisor so as to be abstracted from the physical resources. A host fabric reviews requests to instantiate or upgrade a virtual machine, identifies a corresponding virtual machine image to instantiate the virtual machine from in order to honor the request, and determines whether the virtual machine to be instantiated has a valid lease on the virtual machine image. If the requestor does not have a valid lease, the request is blocked. If the requestor does have a valid lease, the host fabric facilitates the instantiation of the virtual machine from the virtual machine image. This prevents or eliminates the chances of multiple instances of the same virtual machine image writing to the virtual machine image at the same time.
摘要翻译：一种系统，其包括多个主机，每个主机具有物理资源，虚拟机管理程序和主机代理，使虚拟机在虚拟机管理程序之上运行，从物理资源抽象出来。主机结构审查请求实例化或升级虚拟机，识别相应的虚拟机映像以实例化虚拟机以便遵守该请求，并确定要实例化的虚拟机是否具有虚拟机映像上的有效租约。如果请求者没有有效的租约，则该请求被阻止。如果请求者确实具有有效的租约，则主机架构便于虚拟机映像实例化虚拟机。这可以防止或消除同一虚拟机映像同时写入虚拟机映像的多个实例的机会。
