clone or copy images help

[planohog]

Greetings, i am a converted xen user, proxmox loaded nicely and was
able to use all 32G of my memory.. Ok I have created a centos5.2 image
that I have loaded with all my goodies. I need to be able to clone this
image to use for deployment. Yes I will have to change the ip every time but
that is low hanging fruit. Can you give me some instruction on how to do this. thanks in advance. -tm

Do you talk about KVM or OpenVZ on Proxmox VE?
(OpenVZ is our preferred for running Linux)

 

[planohog]

OpenVZ is main container but KVM may be good to know as well..

Probably the best way to do this with openvz would be to create a new template. I've done this with ubuntu, and it should probably be the same with centos.

Assuming your container ID is 101 and that you have stopped your container:

Remove the ip address of the container:

vzctl set 101 --ipdel all --save

then tar the private area to the template file you want. Make sure the first word of your new template is 'centos' (this helps openVZ find the right config template to use with newly created containers).

cd /var/lib/vz/private/101
tar czf /var/lib/vz/template/cache/centos-5.2-custom.tar.gz .

You should now see that template as an option when creating new containers.

You can also use vzdump to backup and then restore multiple times.
