"The CloudStack administrator should monitor the total number of VM instances"
" in each cluster, and disable allocation to the cluster if the total is "
"approaching the maximum that the hypervisor can handle. Be sure to leave a "
"safety margin to allow for the possibility of one or more hosts failing, "
"which would increase the VM load on the other hosts as the VMs are "
"automatically redeployed. Consult the documentation for your chosen "
"hypervisor to find the maximum permitted number of VMs per host, then use "
"CloudStack global configuration settings to set this as the default limit. "
"Monitor the VM activity in each cluster at all times. Keep the total number "
"of VMs below a safe level that allows for the occasional host failure. For "
"example, if there are N hosts in the cluster, and you want to allow for one "
"host in the cluster to be down at any given time, the total number of VM "
"instances you can permit in the cluster is at most (N-1) \\* (per-host-"
"limit). Once a cluster reaches this number of VMs, use the CloudStack UI to "
"disable allocation of more VMs to the cluster."
msgstr "管理员应该监视每个集群中的虚拟机实例的总数，如果总量快达到hypervisor允许的最大虚拟机数量时，不再向此群集分配虚拟机。并且，要注意为主机预留一定的计算能力，以防止群集中有主机发生故障,因为发生故障的主机上的虚拟机需要重新部署在这些预留主机上。请咨询您所选择hypervisor的文档，了解此hypervisor能支持的最大虚拟机数量，并将此数值设置在CloudStack的全局设置里。监控每个群集里虚拟机的活跃程序，并将活跃虚拟机保持在一个安全线内。这样，CloudStack就能允许偶尔的主机故障。举个示例：如果集群里有N个主机，而你只能让其中任一主机的停机时间不超过特定时间。那么，你能在此集群部署的最多虚拟主机数量值为：(N-1) \\* (每主机最大虚拟量数量限值)。一旦群集中的虚拟机达到此数量，必须在CloudStack的用户界面中禁止向此群集分配新的虚拟机。"
