}计算规格使用cpuNum和cpuSpeed来定义云主机的CPU容量。 cpuNum直接代表了云主机所拥有的VCPU数量；cpuSpeed有些特别：云主机的VCPU总是和物理主机上的物理CPU有相同的频率， 这里的cpuSpeed实际上是指在虚拟机管理程序中的VCPU权重（weight）。虚拟机管理程序不同，对于cpuSpeed的使用和实现也不同。
<cputune>
<shares>128</shares>
</cputune>
shares = cpuNum * cpuSpeed创建用户云主机所使用的计算规格。
创建云路由（virtual router）云主机所使用的计算规格。
分配策略定义了选择用于创建云主机的物理主机的算法。
