If you need to create an exact copy of an existing VE, these are the steps to make. Execute these commands as root.

OLDVE=222 NEWVE=333 # Just an example
vzctl stop $OLDVE
mkdir /vz/root/$NEWVE
cp /etc/vz/conf/$OLDVE.conf /etc/vz/conf/$NEWVE.conf
mkdir /vz/private/$NEWVE
pushd /vz/private/$OLDVE; tar c --numeric-owner * | tar x --numeric-owner -C /vz/private/$NEWVE; popd
nano /etc/vz/conf/$NEWVE.conf # Change the all CTIDs from the old CT to the cloned one. And change the IP.
vzctl start $NEWVE; vzctl start $OLDVE

In case you are making bridge don't forget, before start the VEs, to change host_ifname=veth$OLDVE by host_ifname=veth$NEWVE in the /etc/vz/conf/$NEWVE.conf file
