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系统上通过virt-p2v进行过虚拟化转换（详见《Centos 6下通过virt-p2v进行虚拟化服务器转换》一文），然而在Centos 7系统中，virt-p2v client的界面有所变化，并且在virt-p2v server上找不到virt-v2v.conf文件。下面我们将探讨如何在Centos 7系统中进行虚拟化服务器的转换。
客户端配置 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链接中可以找到virt-p2v的安装文件，然后在/usr/share/virt-p2v目录下找到virt-p2v的iso文件。参照《Centos 6下通过virt-p2v进行虚拟化服务器转换》的步骤，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Centos 6系统中，virt-v2v的版本还需要通过virt-v2v.conf文件进行配置，但在Centos 7系统中，virt-v2v不再需要这个文件，因此可以在客户端直接指定pool。
虚拟化服务器 1.将U盘插入服务器，并设置U盘为第一启动项，我们将看到如下界面
2.设置IP地址，点击“configure network”来设置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服务器的IP地址和root密码
4.测试client和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，确保服务器名称是唯一的，不能有重复。在“output to”中选择“libvirt”，然后在“output Storage”中填写pool-1，这是之前在virt-p2v server中创建的pool。点击“start convert”后，客户端将进入如下界面，进行转换。
等待转换完成后，会显示如下界面
6.转换成功后，启动转换完成的虚拟机。首先查看该VM的xml文件，位于/etc/libvirt/qemu目录下。
<domain type="kvm"><name>Centos7-2</name><uuid>107049bd-5a50-4442-a72b-297dc9420684</uuid><memory unit="KiB">2097152</memory><currentmemory unit="KiB">2097152</currentmemory><vcpu placement="static">1</vcpu><os><type arch="x86_64" machine="pc-i440fx-rhel7.2.0">hvm</type><boot dev="hd"></boot></os><features><acpi></acpi><apic></apic></features><clock offset="utc"></clock><on_poweroff>destroy</on_poweroff><on_reboot>restart</on_reboot><on_crash>restart</on_crash><devices><emulator>/usr/libexec/qemu-kvm</emulator><disk device="disk" type="volume"><driver cache="none" name="qemu" type="raw"></driver><target bus="virtio" dev="vda"></target><address bus="0x00" domain="0x0000" function="0x0" slot="0x04" type="pci"></address> </disk><disk device="cdrom" type="file"><driver name="qemu" type="raw"></driver><target bus="ide" dev="hda"></target><readonly></readonly><address bus="0" controller="0" target="0" type="drive" unit="0"></address> </disk><controller index="0" type="usb"><address bus="0x00" domain="0x0000" function="0x2" slot="0x01" type="pci"></address> </controller><controller index="0" model="pci-root" type="pci"></controller><controller index="0" type="ide"><address bus="0x00" domain="0x0000" function="0x1" slot="0x01" type="pci"></address> </controller><interface type="network"><mac address="00:0c:29:5c:30:d0"></mac><model type="virtio"></model><address bus="0x00" domain="0x0000" function="0x0" slot="0x03" type="pci"></address> </interface><serial type="pty"><target port="0"></target></serial><console type="pty"><target port="0" type="serial"></target></console><graphics autoport="yes" port="-1" type="vnc"></graphics><video><model heads="1" type="cirrus" vram="16384"></model><address bus="0x00" domain="0x0000" function="0x0" slot="0x02" type="pci"></address> </video><memballoon model="virtio"><address bus="0x00" domain="0x0000" function="0x0" slot="0x05" type="pci"></address> </memballoon></devices></domain>
主要查看network选项，初始设置为default。首先查看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
我们需要将default修改为vdsm-ovirtmgmt
<interface type="network"><mac address="00:0c:29:5c:30:d0"></mac><model type="virtio"></model><address bus="0x00" domain="0x0000" function="0x0" slot="0x03" type="pci"></address> </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 Centos7-2Domain Centos7-2 started
查看Centos7-2使用的vnc port，为10.10.200.227:0

在Windows PC端通过vnc viewer连接10.10.200.227:0，即可连接到虚拟化后的服务器。
注意：在当前版本的virt-p2v下，转换Centos 6的服务器无法成功，原因不明，且没有提示任何错误。
