NAME
vzmigrate - utility for virtual environment migration between hardware nodes.SYNOPSIS
- vzmigrate [-r|--remove-area yes|no] [--ssh=ssh_options] [--keep-dst] [--online] [-v] destination_address veid
DESCRIPTION
This utility is used to migrate a VE from one (source) Hardware Node (HN) to another (destination) HN. The utility can migrate either stopped or running VE. For a stopped VE, simple VE private area transfer is performed (rsync(1) is used for file transfer). For running VEs, migration may be offline (default) or online.This program uses ssh as a transport layer. You will need to put ssh public key to destination node and be able to connect to node without entering password.
OPTIONS
- -r, --remove-area yes|no
- Whether to remove a VE area on source HN for the successfully migrated VE.
- --ssh=options
- Additional options that will be passed to ssh while establishing connection to destination HN. You may add options like -c blowfish or the like.
- --keep-dst
- Do not clean synced destination VE private area in case of some error. It makes sense to use this option on big VE migration to avoid syncing VE private area again in case some error (on VE stop for example) occurs during first migration attempt.
- --online
- Perform online (zero-downtime) migration: during the migration the VE hangs for a while and after the migration it continues working as though nothing has happened.
- -v
- Verbose mode. Causes vzmigrate to print debugging messages about its progress.
EXAMPLES
Migration of VE #101 to 192.168.1.130 with downtime:vzmigrate 192.168.1.130 101
Online migration of VE#102 to 192.168.1.130:
vzmigrate --online 192.168.1.130 102
