Centos7下通过virt-p2v虚拟化Centos7服务器

# 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)][Centos 6_virt-p2v_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 [Centos 6下通过virt-p2v进行虚拟化转化(For Linux Server)][Centos 6_virt-p2v_For Linux Server]的操作步骤，将该iso文件写入U盘。

## 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

![Center][]

2.设置ip地址，点击“configure network”设置ip地址

![Center 1][]

点击“edit”

![Center 2][]

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

![Center 3][]

4.测试client及server的连接，点击“Test Connection”

![Center 4][]

5,.设置虚拟化选项

![Center 5][]

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。

![Center 6][]

等待转换完成后，会提示如下界面

![Center 7][]

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

        </memballoon>
      </devices>
    </domain>

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

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。
