OpenStack的Resize和冷迁移代码解析及改进

原文:http://www.hengtianyun.com/download-show-id-79.html OpenStack的Resize(升级)功能,我们可以改变虚拟机的CPU核数.内存及磁盘大小,当然虚拟机只能向上升级,不允许向下降级.通过分析源代码,我们发现Resize的过程其实就是冷迁移的过程,Resize多传进去了一个flavor参数.下面将分析OpenStack升级虚拟机和冷迁移的功能. 一.前端入口 (一) Resize /usr/share/openstack-dashboa

openstack instance add cinder-volumes

给instance挂载volumes[云硬盘] 步骤: 通过cinder服务创建一块硬盘volume,挂载到instance上. 一.在instance上操作: fdisk /dev/vdb                  #一般第一次挂载是在这个目录下: p n 1 回车 回车 wq mkfs.ext4 /dev/vdb1 mount /dev/vdb1 /mnt            #看个人需求挂载到一个目录下: 注意:不要随便把volume挂载到/目录下. 如果想把volume这块空间

openstack instance change storage dir

在云计算openstack中以为新建的虚拟机都存放在/var/lib/nova/instances中,在新建虚拟机时内存当然不够用,所以可以将nova转移到新的存储位置 以下操作只在计算节点上进行 一:停止虚拟机   查看虚拟机:   $nova list   停止将要迁移的虚拟机   $nova stop INSTANCEID二:数据迁移   $cp -r /var/lib/nova/instances/  /openstack/三:修改虚拟机存储路径 #vi /etc/nova/nova.c

OpenStack之虚机冷迁移代码简析

OpenStack之虚机冷迁移代码简析 前不久我们看了openstack的热迁移代码,并进行了简单的分析.真的,很简单的分析.现在天气凉了,为了应时令,再简析下虚机冷迁移的代码. 还是老样子,前端的Horizon代码就省去了,直接看后端的代码实现,前端通过请求的action进入到nova/api/openstack/compute/contrib/admin_actions.py文件.代码如下: 1 @wsgi.action('migrate') 2 def _migrate(self, req
