allow_resize_to_same_host=true #允许虚拟机后期的资源调整；允许openstack创建的虚拟机，当发现后期CPU、内存、磁盘空间不足时，对虚拟机进行动态调整 resume_guests_state_on_host_boot=true #配置虚拟机自启动；当宿主机启动后，把虚拟机恢复到之前的状态，如果虚拟机之前是关机，则宿主机启动后，虚拟机也是关机状态；如果虚拟机之前是开机状态，则宿主机启动后，虚拟机还是开机状态 cpu_allocation_ratio=8 #CPU超分；把宿主机 1 核CPU，当做 8 核去分；即宿主机的 1 核CPU在openstack看来，就是 8 核CPU；CPU不能超分太多 ram_allocation_ratio=1.0 #内存一般不超分，一般都是 1 比 1，如果想要想要超分的话，最多超分1.2倍或1.5倍，不能太多；超分有好处也有坏处，好处是可以让openstack创建更多的虚拟机；坏处是，假设一个宿主机有3个虚拟机，宿主机内存为100G，超分为1.2倍，在openstack看来就是120G内存，但如果前两台虚拟机一共已经使用了80G内存，第三台虚拟机使用了20G内存，还有20G内存可用，但是会报内存不足，无法分配内存，因为三台机器已经把宿主机的100G内存全部试用完了，虽然openstack显示还有20G内存可用，但是宿主机已经没有内存可以分配了，当宿主机内存用完后，宿主机内核会把占用内存最多的虚拟机kill掉，所以一般内存不进行超分 disk_allocation_ratio=1.0 #磁盘一般也不进行超分，原理与内存超分一致 reserved_host_disk_mb=20480 #配置磁盘保留空间；即预留指定大小的空间给宿主机使用，一般用于宿主机记录日志；预留10G或者20G磁盘空间即可 reserved_host_memory_mb=4096 #配置内存保留；即预留指定大小的内存给宿主机使用；一般预留4G service_down_time=120 #服务下线时间阈值，默认60，如果一个节点上的 nova 服务超过这个时间没有上报心跳到数据库，api 服务会认为该服务已经下线，如果配置过短或过长，都会导致误判。 rpc_response_timeout=300 #RPC 调用超时时间，由于 Python 的单进程不能真正的并发，所以 RPC 请求可能不能及时响应，尤其是目标节点在执行耗时较长的定时任务时，所以需要综合考虑超时时间和等待容忍时间。设置内存超售比例为1.5倍[root@controller images]# vim /etc/nova/nova.conf ######修改前##### #ram_allocation_ratio=1.0 ################ ######修改后######
