1. 使用ConfigDrive的场景下，NetworkManager会overwrite DNS
1 # /etc/NetworkManager/NetworkManager.conf 2 [main] 3 dns=none

2.安装cloud-init
1.源安装：http://www.ibm.com/support/knowledgecenter/SSB27U_6.3.0/com.ibm.zvm.v630.hcpo4/instslesmore.htm
2.rpm包安装
a.生成rpm包，cloud-init/packages/brpm
b.yum install cloud-init-0.7.7-1.el7.centos.noarch.rpm
3. Nova 使用configDrive
#1.nova启用ConfigDrive nova boot --config-drive true --flavor m1.small --image centos6 --nic net-id=xxxxxxxx --key-name controller --user-data ./my-user-data.txt instance-003 #2.查看configDrive配置 mkdir -p /mnt/config mount /dev/disk/by-label/config-2 /mnt/config #3.configdrive #cloud-config chpasswd: list: | centos:passw0rd expire: False ssh_pwauth: True hostname: host001 runcmd: - [ service, ssh, restart ] #!/bin/sh passwd centos<<EOF passw0rd passw0rd EOF sed -i ‘s/PasswordAuthentication no/PasswordAuthentication yes/g‘ /etc/ssh/sshd_config service ssh restart
