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)
vps-net_add WARNING: arpsend -c 1 -w 1 -D -e xxx.xxx.xxx.xxx (VPS's IP) bond0 FAILED
arpsend: xxx.xxx.xxx.xxx (VPS's IP)8 is detected on another computer : 00:00:00:00:00:00 (MAC address of old node)
vps-net_add WARNING: arpsend -c 1 -w 1 -D -e xxx.xxx.xxx.xxx (VPS's IP) bond0 FAILED
arpsend: xxx.xxx.xxx.xxx (VPS's IP) is detected on another computer : 00:00:00:00:00:00 (MAC address of old node)
vps-net_add WARNING: arpsend -c 1 -w 1 -D -e xxx.xxx.xxx.xxx (VPS's IP) bond0 FAILED
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.
