VM级别的复制由管理程序进行管理，并监控它们的输出(在它们可见之前)，以便检测它们，然后从内部处理器错误进行恢复。

Replication at the VM level is managed by the hypervisor and monitors their outputs (before they are visible) to detect, and then recover from internal processor faults.

所以，在峰值期间，每当三个处理单位可用时，系统管理程序将把两个处理器单位分配给事务服务器，把一个处理器单位分配给报表服务器。

So for every three processing units that are available during the peak, the hypervisor will assign two processor units to the Transaction server and one to the Report server.

因此，新的处理器提供DMA地址转换和权限检查以实现有效的设备透传，而不是捕获并模拟对管理程序下的物理设备的访问。

So, instead of catching and emulating access to physical devices below the hypervisor, new processors provide DMA address translation and permissions checking for efficient device passthrough.
