第一种方法：直接迁移
    1、开启ESXI上的ssh服务和ESXI Shell服务。
    ESXI5.5如下：
    image.png
    ESXI6.7如下：
    image.png

    2、配置KVM到ESXI免密认证

    1. [root@SIT-KVM01  ~]# ssh-keygen 
    2. Generating public/private rsa key pair.
    3. Enter file in which to save the key (/root/.ssh/id_rsa):
    4. Created directory '/root/.ssh'.
    5. Enter passphrase (empty for no passphrase):
    6. Enter same passphrase again:
    7. Your identification has been saved in /root/.ssh/id_rsa.
    8. Your public key has been saved in /root/.ssh/id_rsa.pub.
    9. The key fingerprint is:
    10. SHA256:Cd2XpDjQiR0Nz1eGRDcJhQFm6hyapIXLQ3BeAzRectk root@SIT-KVM01 
    11. The key's randomart image is:
    12. +---[RSA 2048]----+
    13. |  ...o=++. |
    14. |   = Bo+EO.oo=.. |
    15. |    = + * = +    |
    16. |   o = * + o     |
    17. |    = o S        |
    18. |     .           |
    19. |                 |
    20. |                 |
    21. |                 |
    22. +----[SHA256]-----+
    23. [root@SIT-KVM01  ~]# ssh-copy-id -i .ssh/id_rsa.pub 10.xxx.128.145 
    24. /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: ".ssh/id_rsa.pub"
    25. The authenticity of host '10.xxx.128.145 (10.xxx.128.145)' can't be established.
    26. RSA key fingerprint is SHA256:DUhcdrc8dWdwMVv6RwOQs9AVjonPqIFwD7kumhURcjQ.
    27. RSA key fingerprint is MD5:86:2f:b2:02:e4:75:6b:13:3e:ec:32:48:c9:01:85:d3.
    28. Are you sure you want to continue connecting (yes/no)? yes
    29. /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
    30. /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
    31. Password:
    32. Number of key(s) added: 1
    33. Now try logging into the machine, with:   "ssh '10.xxx.128.145'"
    34. and check to make sure that only the key(s) you wanted were added.
    35. [root@SIT-KVM01  ~]#

    3、调整ESXI中上一步添加的KEY认证文件

    1. [root@SIT-KVM01 ~]# ssh 10.xxx.128.145
    2. Password: 
    3. The time and date of this login have been sent to the system logs.
    5. VMware offers supported, powerful system administration tools.  Please
    6. see www.vmware.com/go/sysadmintools for details.
    8. The ESXi Shell can be disabled by an administrative user. See the
    9. vSphere Security documentation for more information.
    10. ~ # cd /etc/ssh/
    11. /etc/ssh # ls
    12. keys-root             moduli                ssh_host_dsa_key      ssh_host_dsa_key.pub  ssh_host_rsa_key      ssh_host_rsa_key.pub  sshd_config
    13. /etc/ssh # cd keys-root/
    14. /etc/ssh/keys-root # ls
    15. authorized_keys
    16. /etc/ssh/keys-root # cd
    17. ~ # cat .ssh/authorized_keys >> /etc/ssh/keys-root/authorized_keys 
    18. ~ # exit
    19. Connection to 10.xxx.128.145 closed.
    20. [root@SIT-KVM01 ~]# ssh 10.xxx.128.145
    21. The time and date of this login have been sent to the system logs.
    23. VMware offers supported, powerful system administration tools.  Please
    24. see www.vmware.com/go/sysadmintools for details.
    26. The ESXi Shell can be disabled by an administrative user. See the
    27. vSphere Security documentation for more information.
    28. ~ #

    4、开始迁移，（注：迁移前需要将虚拟机关机,虚拟机路径里面不要包含空格，中文字符，否则汇报URI错误）。

    1. [root@SIT-KVM01 ~]# eval `ssh-agent`
    2. Agent pid 30714
    3. [root@SIT-KVM01 ~]# ssh-add .ssh/id_rsa
    4. Identity added: .ssh/id_rsa (.ssh/id_rsa)
    5. [root@SIT-KVM01 ~]# export LIBGUESTFS_BACKEND=direct
    6. [root@SIT-KVM01 vmfs]# virt-v2v -i vmx -it ssh "ssh://root@10.xxx.128.145/vmfs/volumes/553503c1-37053e17-f472-a0369f6/d1search02--10.xxx.128.55/d1search02--10.xxx.128.55.vmx" -os vmfs -of qcow2 --bridge br128

    23. Pool vmfs refreshed
    25. Domain d1search02--10.xxx.128.55 defined from /tmp/v2vlibvirt56ad9d.xml
    27. [2321.4] Finishing off
    29. [root@SIT-KVM01 ~]# virt-v2v -i vmx -it ssh "ssh://root@10.xxx.128.145/vmfs/volumes/553503c1-37053e17-f472-a0369f677064/sitdns2 --10.xxx.128.203/sitdns2 --10.xxx.128.203.vmx" -os vmfs -of qcow2 --bridge br128

    33. --10.xxx.128.203/sitdns2 --10.xxx.128.203.vmx’ could not be parsed as a 
    34. URI

    5、查看迁移完成的虚拟机。

    1. [root@SIT-KVM01 ~]# virsh list --all
    2.  Id    Name                           State
    3. ----------------------------------------------------
    4.  1     d1test-10.xxx.128.213          running
    5.  2     d1rongyiwang-10.xxx.128.135    running
    6.  3     d1search02--10.xxx.128.55      running
    7.  4     D1openAPI--10.xxx.128.239--IBM running
    8.  5     d1search04-10.xxx.128.136      running

    第二种方法：将虚拟机导出为OVF模板，然后转换为KVM。

    1. [root@SIT-KVM01 OVF]# virt-v2v -i ova 'sitdns2 --10.xxx.128.203' -os vmfs -of qcow2 -b br128
    2. [   0.0] Opening the source -i ova sitdns2 --10.xxx.128.203

    18. Pool vmfs refreshed
    20. Domain sitdns2 --10.xxx.128.203 defined from /tmp/v2vlibvirt3a4adb.xml
    22. [ 247.0] Finishing off
    24. [root@SIT-KVM01 OVF]# virsh list --all
    25.  Id    Name                           State
    26. ----------------------------------------------------
    27.  1     d1test-10.xxx.128.213          running
    28.  2     d1rongyiwang-10.xxx.128.135    running

    33.  7     sitdns2 --10.xxx.128.203       running

    第三种方法：将虚拟机导出为OVF模板，然后将磁盘文件转换为KVM磁盘文件格式，再导入KVM。

    1. [root@SIT-KVM01 OVF]#qemu-img convert -f vmdk -O qcow2 redhat-6.5--10.xxx.128.136-disk1.vmdk redhat-6.5--10.xxx.128.136-disk1.qcow2
    2. [root@SIT-KVM01 OVF]#virt-manager
