OpenVZ to Virtuozzo 7 Migration

You can migrate containers from a server running OpenVZ based on kernels 2.6.18 and 2.6.32 to a Virtuozzo 7 server by means of the ovztransfer.sh script freely available at https:src.openvz.org/scm/ovzl/ovztransfer.git. Do the following:

• Install the SSH key on the destination server for the root user. To do this, on the source server generate a key with

ssh-keygen

-t

rsa , then transfer the key to the destination server with ssh-copy-id

root@<dest_server> .

• Clone the repository with the script to the source OpenVZ server with

git

clone

https://src.openvz.org/scm/ovzl/ovztransfer.git .

• Change to the

/ovztransfer directory and make the script executable with chmod

755

ovztransfer.sh .

• Run the script on the source OpenVZ server as follows:

# ./ovztransfer.sh <dest_server> <source_CT1_ID>[:<new_CT1_name>] \ [ … <source_CTn_ID>[:<new_CTn_name>]]

where <source_CT_ID> (the source container ID) and <new_CT_name> (the new container name) must both be specified in the old numerical ID format. For example:

# ./ovztransfer.sh 192.168.0.10 100:200

So, in the example above, 200 will be the name of the resulting ploop-based container on the Virtuozzo 7 server, even though said name looks like an old numerical ID.
