I try to migrate a VE from one HN to another one with the exact same kernel (2.6.9-023stab043.2-smp). On both machines, Quota is disabled in /etc/vz/vz.conf (DISK_QUOTA=no).

This is what I get:

/usr/sbin/vzmigrate -r no --online -v 195.141.118.235 134

Seems like You dont have the checkpointing (cpt) module compiled/loaded?
Im not sure if it is built in 2.6.9, it isnt in 2.6.20 for sure.

I saw here ( http://forum.openvz.org/index.php?t=tree&th=885&mid= 4794&&rev=&reveal=) that test kernel are needed, but this was almost 1 year ago. Is checkpointing now not in the stable kernel?

And: is it needed on both sides or only on the source node?

You need to use a 2.6.18 kernel. 2.6.9 openvz does not support checkpointing, which is using for live migration.

Are you sure? ...sorry but my vzmigrate works fine with 2.6.9stab kernel (Between CentOS4-Nodes). I migrate Slackware- and CentOS-VPS online with vzmigrate. So i think it's possible to migrate online with kernel 2.6.9stab. (My english maybe very bad but my online-migration with 2.6.9stab kernel works very good Wink)

Please load CPT modules on both nodes:
modprobe vzcpt
modprobe vzrst


What kernel version do you use?
