Virt-v2v tools automatically migrate vmware to kvm

If the virtual machine is a virtual machine of ESXi, then we can use virt-v2v 's tools to migrate automatically.

The virt-v2v tool can migrate virtual machines from other hypervisor platforms to KVM.

It can read virtual machines on the Xen,Hyper-v,VMware platform and migrate them to KVM,openstack or RHEV environments managed by libvirt.

This section only focuses on how to migrate virtual machines to KVM on ESCi, and you only need to convert images and import to openstack and RHEV without going into detail.

KVM storage pool configuration proc

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

Create an ESXi certification file

(this step is not a necessary step. If you do not configure it, you need to change the command slightly when using virt-v2v.)

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 ~] #

Start the migration

Test to see if you can connect to the ESXi host before starting the migration

Virsh-c esx://192.168.24.13/?no_verify=1 list-- all

If you can see the host running on this ESXi, there is no problem with the connection.

[root@amckvm2] # virsh-c esx://192.168.24.13/?no_verify=1 list-- all

Enter username for 192.168.24.13 [root]:

Enter root's password for 192.168.24.13:

Id Name State

-rhel6.5_db_model_192.168.24.231 shut off

-windows2008_model shut off

Start the migration

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

Note:

1. If you encounter an error like "Peer certificate cannot be authenticated with given CA certificates", ignore the certificate check by setting the no_verify=1 parameter after url.

two。 The whole url is made up of user@esxi. If the authentication file is not created in 3.2, you need to change the command to the following

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. If the user name is a domain account (domain\ name) or the virtual machine name contains a backslash, the backslash needs to be transcoded and "% 5c" is used instead of "\".

4.-os represents the storage pool specified in KVM,-of represents the virtual disk format transferred out of the migration, and the thing I specify here, qcow2,-b, represents the virtual bridge in the specified KVM.

The output is as follows

[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

Virt-v2v: inner-db configured without virtio drivers.
