i tried to play with checkpointing
http://wiki.openvz.org/Checkpointing_and_live_migration
first time i made dump and restore on same host and all was ok.
sudo vzctl start 2
sudo vzctl chkpnt 2 --suspend
sudo vzctl chkpnt 2 --dump --dumpfile /home/dagr/2.dump
sudo vzctl chkpnt 2 --kill
sudo vzctl restore 2 --undump --dumpfile /home/dagr/2.dump
sudo vzctl restore 2 --resume
VPS - was default centos - inside sendmail processes .
after that i entered VPS - run this commands
screen
top -d 1
// then detached ssh client - and after relogining i saw screen and top procceses inside vps - it was ok .
then repeated all above with chkpointing and got at the end
[dagr@mydbtest ~]$ sudo vzctl restore 2 --undump --dumpfile /home/dagr/2.dump
