vzmigrate - utility for virtual environment migration between hardware nodes.
- vzmigrate [-r|--remove-area yes|no]
[--ssh=ssh_options] [--keep-dst] [--online]
[-v] destination_address veid
-
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.
- -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.
