[one-users] Creating virtual machines from scratch

[richard -rw- weinberger]

Hi!

I'm a bit confused how to create a vm from scratch.
Assume I want a vm running with CentOS6 and a new virtual hard disk of 500GiB.

How can I create a new disk using OpenNebula (especially with Sunstone)?

In my setup each vm will have it's own disk image, thus no disk image
needs to be copied.
Is there a way to enforce this?

A final question, is it possible to change the boot order of a vm?
Do I really have to delete and recreate it?
