Live migration fails

[yohannp]

I can't launch live migration of OpenVZ container between two proxmox nodes...

Feb 05 03:30:27 starting migration of CT 102 to node 'madrid' (xx.xx.xx.xx)
Feb 05 03:30:27 container is running - using online migration
Feb 05 03:30:27 starting rsync phase 1
Feb 05 03:30:27 # /usr/bin/rsync -aHAX --delete --numeric-ids --sparse /var/lib/vz/private/102 root@xx.xx.xx.xx:/var/lib/vz/private
Feb 05 03:30:36 start live migration - suspending container
Feb 05 03:30:36 dump container state
Feb 05 03:30:36 # vzctl --skiplock chkpnt 102 --dump --dumpfile /var/lib/vz/dump/dump.102
Feb 05 03:30:36 Setting up checkpoint...

I have iptables-persistent installed on both nodes, and on the container to migrate. iptables-save output is well expected...

Do you have any idea ?

Thanks by advance !
