Hi,

I restarted vz on the destination... in vain. The destination is a fresh install of CentOS 4 and openvz.

I tried without the --online and it worked.

Please note that my /vz is not at /vz, but at /home/vz/ on the source server. On the destination server, the VM got migrated to /home/vz/ correctly when not using the --online option.

Regards,

Ugo

The migration process failed not due to quota.
It is failed because of this:
Error: undump failed: Invalid argumentStopping VE ...

Restoring failed:
iptables-restore exited with 1
rst_restore_net: -22


Can you give an access to this nodes to investigate this issue? If you can, then please post it via PM.

After some investigation on your node I have found that some iptables modules are not loaded on destination node.

On source node in /etc/vz/vz.conf we have:
IPTABLES="ipt_REJECT ipt_tos ipt_TOS ipt_LOG ip_conntrack ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length ipt_state iptable_nat ip_nat_ftp"

On destination node we have:
IPTABLES="ip_tables ipt_REJECT ipt_tos ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length"

After changing this value on dst node and restarting vz service I was able to migrate this VE.

Andrey, probably we should add the check of required modules in vzmigrate?..
