    OpenVZ and Vzmigrate

    Hi all,

    We've run into a few problems with migrating to a new nodes from our previous one. Both are on the same network while one is Centos 32bit the newer one is 64bit. The VPS's will keep the same IPs so there won't be donwtime.

    I use the command:

    vzmigrate -r no --keep-dst --online -v xxx.xxx.xxx.xxx VPSID

    However it comes back with errors:

    Error: undump failed: Invalid argument
    Restoring failed:
    Error: iptables-restore exited with 2
    Error: Most probably some iptables modules are not loaded
    Error: rst_restore_net: -22
    Stopping container ...
    Container start failed
    Container was stopped
    Container is unmounted
    Error: Failed to undump container
    Resuming...

    arpsend: xxx.xxx.xxx.xxx (VPS's IP) is detected on another computer : 00:00:00:00:00:00 (MAC address of old node)

    vzquota : (error) Quota is not running for id VPSID


    Any suggestions on how else to migrate these VPS with little or no downtime?

    Thanks.

    I found a fix, it works without the --online command.
