virt-v2v工具自動(dòng)遷移vmware遷移至kvm
virt-v2v工具自動(dòng)遷移vmware遷移至kvm
如果虛機(jī)是ESXi種的虛機(jī)，那么我們可以使用virt-v2v的工具直接進(jìn)行自動(dòng)遷移。
virt-v2v工具可以將其他hypervisor平臺(tái)上的虛擬機(jī)遷移到KVM上。
它可以讀取Xen，Hyper-v，VMware平臺(tái)上的虛擬機(jī)，將它們遷移到由libvirt管理的KVM，openstack或者RHEV環(huán)境中。
本節(jié)只針對(duì)ESCi上如何將虛機(jī)遷移到KVM中，往openstack和RHEV上遷移只需要轉(zhuǎn)換鏡像和導(dǎo)入即可不做贅述。
KVM存儲(chǔ)池配置過(guò)程
mkdir -p /data/vmfs
virsh pool-define-as vmdisk --type dir --target /data/vmfs
virsh pool-build vmdisk
virsh pool-autostart vmdisk
virsh pool-start vmdisk
創(chuàng)建ESXi認(rèn)證文件
（本步驟不是必須步驟，如果不做配置的話(huà)則在使用virt-v2v的時(shí)候需要稍微改變命令）
vim /root/.netrc
machine YourESXiServerIPAddress login root password YourESXiServerIPAddress
chmod 0600 ~/.netrc
[root@amckvm2 ~]# cat /root/.netrc
machine 192.168.24.13 login root password password 192.168.24.13
[root@amckvm2 ~]#
開(kāi)始遷移
開(kāi)始遷移前先測(cè)試看是否能夠連接上ESXi主機(jī)
virsh -c esx://192.168.24.13/?no_verify=1 list --all
如果能夠看到運(yùn)行在這個(gè)ESXi上的主機(jī)說(shuō)明連接沒(méi)有問(wèn)題。
[root@amckvm2 ~]# virsh -c esx://192.168.24.13/?no_verify=1 list --all

開(kāi)始遷移
virt-v2v -ic esx://192.168.24.13/?no_verify=1 -os vmdisk -of qcow2 -b br0 rhel6.5_db_model_192.168.24.231
注：
1.如果遇到了類(lèi)似于“ Peer certificate cannot be authenticated with given CA certificates”這一類(lèi)的錯(cuò)誤通過(guò)在url后面設(shè)置no_verify=1 參數(shù)來(lái)忽略證書(shū)檢查。
2.整個(gè)url的組成由user@esxi組成。如果在3.2沒(méi)有創(chuàng)建認(rèn)證文件的話(huà)這里需要將命令改成如下
virt-v2v -ic esx://root@192.168.24.13/no_verify=1 -os vmdisk -of qcow2 -b br0 rhel6.5_db_model_192.168.24.231
3.如果用戶(hù)名使用的是域賬戶(hù)（domain\name）或者虛機(jī)名中包含有反斜線(xiàn)，則反斜線(xiàn)需要轉(zhuǎn)碼特殊標(biāo)示，使用“%5c”代替“\”
4.-os表示指定到KVM中的哪個(gè)存儲(chǔ)池，-of表示遷移轉(zhuǎn)出的虛機(jī)磁盤(pán)格式，我這里指定的事qcow2，-b表示指定KVM中的虛擬網(wǎng)橋。
輸出結(jié)果如下
[root@amckvm2 ~]# virt-v2v -ic esx://192.168.24.13/?no_verify=1 -os vmdisk -of qcow2 -b br0 rhel6.5_db_model_192.168.24.231
