大家好，又见面了，我是你们的朋友全栈君。
环境说明
virt-p2v server：Centos 7.2
virt-p2v client：Centos 7.2
Virt-p2v version：1.28.1
Virt-v2v version： 1.28.1
配置说明
之前在

Centos 6下通过virt-p2v进行虚拟化转化(For Linux Server)这篇Blog中写过在Centos6下通过virt-p2v进行虚拟化服务器，但是发现在Centos7中，virt-p2v client的客户端
界面发生改变，且在virt-p2v server中没有virt-v2v.conf文件，下面我们来看看在Centos7中如何进行虚拟化服务器。
客户端配置
同样在http://rpm.pbone.net/index.php3?stat=26&dist=93&size=263085744&name=virt-p2v-1.28.1-1.51.3.el7.1.noarch.rpm链接中找到virt-p2v的安装文件，然后
在/usr/share/virt-p2v目录下面可以找到virt-p2v的iso文件。参照

服务器配置
安装virt-v2v
#yum -y install virt-v2v
在服务器端创建pool
#virsh pool-create-as pool-1 dir --target=/home/pool1在Centos6中virt-v2v的版本还有virt-v2v.conf文件进行需要配置，但是在Centos7中virt-v2v没有这个文件，所以不需要配置，在客户端直接指定pool就可以了。
虚拟化服务器
1.将U盘插入服务器，设置U盘为第一启动项，我们可以看见如下界面
2.设置ip地址，点击“configure network”设置ip地址
点击“edit”
点击“ipv4 settings”设置ip地址
3.设置连接virt-v2v服务器，分别填写virt-p2v 服务器ip及root密码
4.测试client及server的连接，点击“Test Connection”
5,.设置虚拟化选项
分别设置服务器名称，主要服务器名称是唯一的，不能有相同的，分别在“output to”中选择“libvirt”，而后在“output Storage”中填写pool-1，pool-1为之前在virt-p2v server中创
建的pool。点击“start convert”，而后客户端进入如下所示界面，进行转换。
等待转换完成后，会提示如下界面
6. 转换成功后，开始启动转换完成的虚拟机，先查看到该vm的xml文件，在/etc/libvirt/qemu目录下面可以找到

主要查看network选项为default，先查看virt-p2v server的network列表
[root@ovirt-host-227 qemu]# virsh net-list
Name State Autostart Persistent
----------------------------------------------------------
;vdsmdummy; active no no
vdsm-ovirtmgmt active yes yes
在这里我们需要将default修改为vdsm-ovirtmgmt
<interface type='network'>
<mac address='00:0c:29:5c:30:d0'/>
<source network='vdsm-ovirtmgmt'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
启动vm
[root@ovirt-host-227 qemu]# virsh define Centos7-2.xml
Domain Centos7-2 defined from Centos7-2.xml
[root@ovirt-host-227 qemu]# virsh start Centos7-2
Domain Centos7-2 started
查看Centos7-2所使用的vnc port，为10.10.200.227:0
[root@ovirt-host-227 qemu]# ps -ef | grep vnc

在windows pc端通过vnc view连接10.10.200.227:0，就可以连接上虚拟化后的服务器了。
另：在该版本的virt-p2v下转换Centos 6的服务器无法成功，原因未知，没有提示任何错误。
