Hi,

you can disable to load OpenVZ migration/checkpointing linux kernel modules, vzrst and vzcpt in vz init script

---8<...
if [ "${MODULES_DISABLED}" != "yes" ]; then
PRELOAD_MODULES="af_packet"
MODULES="vzmon vzdquota vzdev"
----> #CPT_MODULES="vzcpt vzrst" <----
MODULES_OTHER="vzcompat ${CPT_MODULES}"
---8<...

or add a directive, in /etc/vz/vz.conf

---8<...
MIGRATION="no"
---8<...

and a patched vz init.d script:

--- /etc/init.d/vz 2009-09-29 09:24:36.336995392 +0200
+++ /etc/init.d/vz-new 2009-09-29 09:26:31.398503384 +0200
