对这些Linux组件进行优化(例如2.6版本内核中的新o(1)调度程序)都可以让系统管理程序(主机操作系统)和Linux客户操作系统同时受益。
Optimizations to these Linux components (such as the new o (1) scheduler in the 2.6 kernel) benefit both the hypervisor (the host operating system) and the Linux guest operating systems.
下一步,使用一个是这个云组一部分的,表明这个新的,系统管理程序的PUT请求来跟进这个POST请求。
Next, follow up the POST request above with a PUT request indicating that the new hypervisor is part of this cloud group.
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.
