1、安装配置VMraer-ESXi平台并创建虚拟机

部署好后浏览器输入VMraer-ESXi的IP地址即可访问：

2、配置v2v转换服务器
yum install -y qemu-kvm libvirt virt-manager virt-v2v
需要迁移win虚机的话，还需安装：
yum install -y libguestfs-winsupport
3、查看源主机的虚拟机
$ virsh -c esx://root@192.168.30.177?no_verify=1 list --all
# 192.168.30.177 为宿主机的ip或者URL</pre>
[root@compute data]# virsh -c esx://root@192.168.30.177?no_verify=1 list --all
Enter root's password for 192.168.30.177:
Id Name State
-----------------------
- guest shut off
4、迁移vm
使用virt-v2v-copy-to-local命令即可把对应的VM迁移到本地，其中需要输入两次密码，两次的密码均为esxi宿主机的登录密码(注意：vm要为shut off状态)
$ virt-v2v-copy-to-local -ic esx://root@192.168.30.177?no_verify=1 guest
# 192.168.30.177 为宿主机的ip或者URL
# guest为迁移的VM名称</pre>
[root@-compute vms]# virt-v2v-copy-to-local -ic esx://root@192.168.30.177?no_verify=1 guest
[ 5.3] Parsing the remote libvirt XML metadata ...

5 16.0G 5 875M 0 0 45.1M 0 0:06:03 0:00:19 0:05:44 45.5M
迁移完成后会在当前目录生成一个xml文件和disk1磁盘文件
5、格式转换
迁移完成后，就需要把磁盘文件的格式转换成OpenStack能够识别的格式
$ virt-v2v -i libvirtxml guest.xml -o local -os /data/vms -of raw
#guest.xml为刚才迁移时生成的xml文件
# -o <glance|libvirt|local|null|openstack|qemu|rhv|rhv-upload|vdsm>
#-os为转换格式后存放的路径
#-of为指定转换的格式为raw <raw|qcow2> </pre>
[root@compute data]# virt-v2v -i libvirtxml guest.xml -o local -os /data/vms/ -of raw

[root@compute data]# ll -h vms

-rw-r--r-- 1 root root 16G Feb 27 10:02 guest-sda
-rw-r--r-- 1 root root 1.5K Feb 27 10:02 guest.xml
会在/data/vms下生成一个raw格式的OpenStack镜像，上传到OpenStack环境中即可使用。
6、上传镜像到openstack
glance image-create --name vmware_guest --disk-format=raw --container-format=bare --file guest-sda
