Duplicate OpenVZ container
How to duplicate container
It's not critical but better to pause or turn off original container before backup/copy
for example original CT ID = 111 and we'll dublicate it in CT ID 222
mkdir /vz/private/222
cp -avr /vz/private/111/* /vz/private/222/
cp /etc/vz/conf/111.conf /etc/vz/conf/222.conf
now edit 222.conf and change IP address and you can start it after.
In case you get any quota related issues try to run this command:
lsof 2> /dev/null | egrep '/vz/root/222|/vz/private/222'
if you see output like:
cp 94846 root 4w REG 9,2 14540 4863092 /vz/private/3030/epel-release-6-8.noarch.rpm
simply kill PID:
kill -9 94846
