    • One or more techniques and/or systems are provided for hosting a virtual machine from a snapshot. In particular, a snapshot of a virtual machine hosted on a primary computing device may be created. The virtual machine may be hosted on a secondary computing device using the snapshot, for example, when a failure of the virtual machine on the primary computing device occurs. If a virtual machine type (format) of the snapshot is not supported by the secondary computing device, then the virtual machine within the snapshot may be converted to a virtual machine type supported by the secondary computing device. In this way, the virtual machine may be operable and/or accessible on the secondary computing device despite the failure. Hosting the virtual machine on the secondary computing device provides, among other things, fault tolerance for the virtual machine and/or applications comprised therein.
    • 提供一个或多个技术和/或系统用于从快照托管虚拟机。 特别地,可以创建主计算设备上托管的虚拟机的快照。 虚拟机可以使用快照来托管在辅助计算设备上,例如当主计算设备上的虚拟机发生故障时。 如果辅助计算设备不支持快照的虚拟机类型(格式),则快照中的虚拟机可能会转换为辅助计算设备支持的虚拟机类型。 以这种方式,虚拟机可以在辅助计算设备上可操作和/或可访问,尽管失败。 在辅助计算设备上托管虚拟机尤其提供了虚拟机和/或其中包含的应用的容错。
