因为某些原因公司需要吧VMware Esxi 虚拟机迁移到OpenStack平台，下面描述一下迁移步骤

条件需求

迁移 vmware esxi虚拟机：

IP：10.10.235.250

**机器在Esxi的名称：**yum-运维-[10.10.235.250]

所在宿主机ip： 10.10.233.11

迁移方式：冷迁移，需要提前关闭对应虚拟机。

需提前准备好该虚拟机所在物理机Esxi的账号密码。

OpenStack操作节点：

ip地址：10.10.214.11

主机名：szsjhl-control-test-10-10-214-11-vm.belle.lan

迁移步骤：

查看vmware esxi宿主机上所有的虚拟机列表

开启Esxi宿主机ssh，在10.10.214.11上面执行：virsh -c esx://root@宿主机IP?no_verify=1 list --all

# virsh -c esx://root@10.10.233.11?no_verify=1 list --all

创建用于存放文件的目录（可选）

# mkdir -p /data/esxi-vm
# cd /data/esxi-vm/

拷贝虚拟机到本地

拷贝完成后会在当前目录生成一个xml文件和disk1磁盘文件

virt-v2v-copy-to-local -ic esx://root@宿主机IP?no_verify=1虚拟机名称

# virt-v2v-copy-to-local -ic esx://root@10.10.233.11?no_verify=1 yum-[10.10.235.250]

查看生成的xml文件和disk1磁盘文件

-rw-r--r-- 1 root root 1168 Apr 6 16:10 yum-[10.10.235.250].xml

转换数据格式

把磁盘文件的格式转换成OpenStack能够识别的格式

转换磁盘文件格式

raw 和 qcow2 两种格式都支持，qcow2格式：空间占用小、传输快等等。

#qemu-img convert -f raw -O qcow2 yum-[10.10.235.250]-sda yum-[10.10.235.250]-sda.qcow2

-rw-r--r-- 1 root root 1.5K Apr 6 16:32 yum-[10.10.235.250].xml

上传镜像到glance

# openstack image create "yum-[10.10.235.250]" --file yum-[10.10.235.250]-sda.qcow2 --disk-format qcow2 --container-format bare --public

# openstack image list

从控制台上用新上传的镜像创建新虚拟机，可能会缺少部分实例类型，需要新创建对应实例类型

新创建完新虚拟机后，需要从页面控制台进入新虚拟机中更改一下IP地址，改为openstack中新获取的IP，不然机器无法连接登录。
