Just copy your VPS directory (/vz/private/200) to the new
directory (/vz/private/201).
Copy config files (200.conf to 201.conf) and edit the last one in a decent way.

Thanks Vasily for the invaluable tip.

However I cannot copy the /vz/priate/200 to /vz/private/201 using the cp command. Of cource, I did mkdir /vz/root/201 /vz/private/201.

Is there any specific way to do it? Please elaborate on what should be the specific command to clone VPSes in the same HN (hardware node).

Thanks in advance.

Why can't you? Smile

In current distribution of OpenVZ there is no specific tool. I guess this is so 'cause of it's very easy to do it by hand:

# vzctl stop 101
Stopping VE ...
VE was stopped
VE is unmounted
# cp -r /vz/priate/101 /vz/private/202
# cp /etc/vz/conf/101.conf /etc/vz/conf/202.conf
# vzctl start 202
Starting VE ...
Initializing quota ...
VE is mounted
Setting CPU units: 1000
VE start in progress...

This can easily be disgned as a shell script.

HTH,
Vasily.

I did exactly as you stated but didn't work, but reported 'omitting directories' error.

I rebooted the HN and did the same and copying worked.

But the new problem after starting the coped VPS.

#vzctl start 202 gives an error message:

"Unable to start init, probably incorrect template, 
VE start failed"

I created and destroyed the 202 earlier with a different distro and also the 202.conf.destroyed has also been removed.

However, when I copied to something new like 211 the ID which was not used before, it worked perfectly.

Could you elaborate what could be the reason or where to tweak in the cases like 202 as stated above?

Thank you for your continued coooperation,

Hmmm,

can you post output of the following commands:

# ls -l /vz/private/<veid>/sbin/ | grep init
# ls -l /vz/private/<veid>/bin/ | grep init

# ls -l /vz/private/<old_veid>/sbin/ | grep init
# ls -l /vz/private/<old_veid>/bin/ | grep init

<veid> is the id of newly created VE.
<old_veid> is the id of original VE.

Tell me, were there some troubles while copying?
Any error messages? Does original VE start?

Thank you.

With the new VE, the above ls command outputs "No such file or Directory"

With the old VE, the first command (sbin dir) shows three files, init, initlog and telinit linked to init

the second command (bin dir) simply executes without any outputs.

And the cp went well without any glitches.

Just want to add for anyone coming accross this thread that it's probably a good idea to use the cp -p option to preserve permissions. I copied a VPS once and root ended up owning everything inside the duplicated VPS which broke a few things.
