有时虚拟机创建后发现虚拟机规格太小，满足不了业务需求。于是需要在线拉伸虚拟机的规格。修改controller和各个computer节点的nova.cnf文件，打开下面两个参数[root@control ~]# vim /etc/nova/nova.conf[root@node ~]# vim /etc/nova/nova.confallow_resize_to_same_host=Truescheduler_default_filters=RetryFilter,AvailabilityZon

1、动态迁移需要使用共享存储在cinder节点上增加共享存储如NFS，虚拟机使用共享存储的卷2、在所有nova计算节点配置libvirtd服务[root@node1 ~]# vim /etc/libvirt/libvirtd.conflisten_tls = 0listen_tcp = 1tcp_port = "16509"listen_addr = "0.0.0.0"auth_tcp = "none"mdns_adv = 03、在所有nova计算节点配置libvirtd监听方式，...
