Hi There

When I try to migrate a VPS from one server to another (source: 2.6.24-6-fza-amd64, destination: 2.6.18-12-fza-amd64) with the command

vzmigrate --online vzhost02 101

the following error appears:

vzhost01:/vz# vzmigrate -v --online vzhost02 101

The guest os is just a plain debian from the template debian-4.0-amd64-minimal.tar.gz with an apache2 installed and running).

Would be great if you can help us!

Thank you a lot in advance

It's not possibile to restore a cpt dump from an
2.6.24 to an 2.6.18 kernel
cpt versions missmatched -> see Error: Unknown image version: 400. Can't restore.

overview, taken from the OpenVZ git tree 2.6.27
[linux-2.6.27-openvz] / include / linux / cpt_image.h

[...]
#define CPT_VERSION_8 0
#define CPT_VERSION_9 0x100
#define CPT_VERSION_9_1 0x101
#define CPT_VERSION_9_2 0x102
#define CPT_VERSION_16 0x200
#define CPT_VERSION_18 0x300
#define CPT_VERSION_18_1 0x301
#define CPT_VERSION_20 0x400
#define CPT_VERSION_24 0x500
#define CPT_VERSION_26 0x600
#define CPT_VERSION_27 0x700

Bye,

and the second error :

[...]
> Error: HZ mismatch: 1000 != 250

target kernel isn't compile with kernel option :
[...]
CONFIG_HZ_1000=y
CONFIG_HZ=1000

on checkpointing/restoring source and target kernels must setup on built with same HZ.

Bye,
Thorsten
