OpenVZ/vzctl how to do an on-line migration without downtime

vzmigrate --online dest-host VEIDNO
eg.: 

vzmigrate --oneline 192.168.1.55 101

One option I would recommend is "--keep-dst", that way if the migration is interrupted you can still bring the VPS back up on the original host.  After the migration is successful you can manually destroy it.

OpenVZ has a good writeup on this including Checkpointing and Restoring etc: http://wiki.openvz.org/Checkpointing_and_live_migration
