1. ESXI将虚拟机导出

导出ova模板

将导出的ova模板导入到KVM环境中。

2. 配置KVM环境

安装所需要的组件

[[email protected] ~]# yum install libvirt* virt-* qemu-kvm* -y  

配置桥接网卡

[[email protected] ~]# virsh iface-bridge eth4 br1  使用附加设备 br1 生成桥接 eth4 失败  已启动桥接接口 br1  

3. 导入虚拟机

启动kvm管理程序，并设置开机自启动

[[email protected] ~]# systemctl start libvirtd.service  [[email protected] ~]# systemctl enable libvirtd.service  

创建虚拟机存放目录

[[email protected] ~]# virt-v2v -i ova centos-dev-test01-v2v.ova -o local -os /vmhost/dev/dev-test01  -of qcow2  [   0.0] Opening the source -i ova centos-dev-test01-v2v.ova  virt-v2v: warning: making OVA directory public readable to work around  libvirt bug https://bugzilla.redhat.com/1045069  [  23.1] Creating an overlay to protect the source from being modified  [  23.4] Initializing the target -o local -os /vmhost/dev/dev-test01  [  23.4] Opening the overlay  [  41.4] Inspecting the overlay  [  57.5] Checking for sufficient free disk space in the guest  [  57.5] Estimating space required on target for each disk  [  57.5] Converting CentOS release 6.9 (Final) to run on KVM  virt-v2v: This guest has virtio drivers installed.

修改网卡配置

修改网卡source network 为桥接

修改网卡使用virtio

[[email protected] dev-test01]# cat centos-dev-test01-v2v.xml  <?xml version='1.0' encoding='utf-8'?>  <domain type='kvm'>    <!-- generated by virt-v2v 1.36.3rhel=7,release=6.el7_4.3,libvirt -->    <name>centos-dev-test01-v2v</name>    <memory unit='KiB'>524288</memory>    <currentMemory unit='KiB'>524288</currentMemory>    <vcpu>1</vcpu>    <features>      <acpi/>      <apic/>    </features>    <os>      <type arch='x86_64'>hvm</type>    </os>    <on_poweroff>destroy</on_poweroff>    <on_reboot>restart</on_reboot>    <on_crash>restart</on_crash>    <devices>      <disk type='file' device='disk'>        <driver name='qemu' type='qcow2' cache='none'/>        <source file='/vmhost/dev/dev-test01/centos-dev-test01-v2v-sda'/>        <target dev='vda' bus='virtio'/>      </disk>      <disk device='cdrom' type='file'>        <driver name='qemu' type='raw'/>        <target dev='hda' bus='ide'/>      </disk>      <disk device='floppy' type='file'>        <driver name='qemu' type='raw'/>        <target dev='fda'/>      </disk>      <interface type='bridge'>        <source bridge='br1'/>        <model type='virtio'/>        <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>      </interface>      <video>        <model type='qxl' ram='65536' heads='1'/>      </video>      <graphics type='vnc' autoport='yes' port='-1'/>      <input type='tablet' bus='usb'/>      <input type='mouse' bus='ps2'/>      <console type='pty'/>    </devices>  </domain>  

4. 启动虚拟机

导入主机

[[email protected] dev-test01]# virsh  define centos-dev-test01-v2v.xml  定义域 centos-dev-test01-v2v（从 centos-dev-test01-v2v.xml）  

查看主机列表

[[email protected] dev-test01]#  virsh list --all   Id    名称                         状态  ----------------------------------------------------   -     centos-dev-test01-v2v          关闭  

启动主机

[[email protected] dev-test01]#  virsh start centos-dev-test01-v2v  域 centos-dev-test01-v2v 已开始  

5. 测试可用性

登陆迁移后的虚拟机测试

[[email protected] ~]# ssh [email protected]  The authenticity of host '192.168.19.123 (192.168.19.123)' can't be established.  RSA key fingerprint is SHA256:iRmghFzgRIJy5+v8p4lqi8DyUG8F0hXR/qNdDZ2J6RY.  RSA key fingerprint is MD5:37:b8:56:3b:b7:85:fa:cb:d9:55:a7:44:d5:de:f8:d9.  Are you sure you want to continue connecting (yes/no)? yes  Warning: Permanently added '192.168.19.123' (RSA) to the list of known hosts.  [email protected]'s password:  Last login: Mon Mar  5 10:30:02 2018 from 192.168.19.9  [[email protected] ~]# hostname  -I  192.168.19.123  

设置虚拟机开机自启动。

[[email protected] ~]# virsh autostart centos-dev-test01-v2v  域 centos-dev-test01-v2v标记为自动开始  

至此第一台机器的迁移完成，后续按照相同的方式将其他的虚拟机进行迁移即可。
