摘要： A system and method are disclosed for managing a plurality of virtual machines (VMs) in a fault-tolerant and low-latency manner. In accordance with one example, a computer system executes a first VM and a second VM, and creates a first live snapshot of the first VM and a second live snapshot of the second VM. The computer system detects, after the creating of the first live snapshot and the second live snapshot, a failure that affects the executing of the first VM, and in response destroys the first VM and the second VM, creates a third VM from the first live snapshot and a fourth VM from the second live snapshot, and initiates execution of the third VM and the fourth VM. An output transmitted by the first VM to the second VM during the creating of the first live snapshot and the second live snapshot is not blocked.

摘要： A para-virtualization method is provided. The method comprises implementing a virtual machine (VM) for guest software running on first host software. In response to a privileged instruction, the guest software causes a first VM exit. If the first host software is not running directly on hardware, the privileged instruction is managed without causing a second VM exit. Otherwise, the privileged instruction is managed normally.
摘要翻译：提供了一种半虚拟化方法。该方法包括为在第一主机软件上运行的客户软件实现虚拟机（VM）。响应特权指令，客户软件导致第一个VM退出。如果第一个主机软件没有直接在硬件上运行，则可以管理特权指令，而不会导致第二个VM退出。否则，特权指令被正常管理。
