3 Lines to live-migrate simply from one to another Node (such as HyperVM VPS):
On the old Node:
Code:
ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub "-p 22 root@new.node.tld"
vzmigrate --ssh="-p 22" --online new.node.tld VPSID
This works perfectly wonderful for me. You can use this for instance in VDSManager-Linux. Requirement is to set the SSH-Port at the slave server settings and make a button to generate a public key.
