hi,

I had encounter error in live migration, after some search (solve the problem in line 382 of vzmigrate), I locate that problem is with checkpoint, because live migration will create a dump (i.e. checkpoint) of the running ve, then restore in the destination ve.

here is the error:

# vzctl chkpnt 2000201
Setting up checkpoint...
        suspend...
        dump...
Can not dump VE: Invalid argument
Error: iptables-save exited with 255
Checkpointing failed


also I have read in some post that it is the bug of one previous kernel ( http://git.openvz.org/?p=linux-2.6.18-openvz;a=commit;h=6507 23f83a8685111fb3dee7073454861c446193).

my configuration:

platform: gentoo, well maintained
kernel version: 2.6.18-028stab053-r2
vzctl: 3.0.22
vzquota:3.0.11

it will be thankful if anyone could point me out.
