This page allows you to create a new system image from an existing virtual
system managed by Cloudmin. The entire contents of the system's filesystem will be
frozen and copied into an image file on the Cloudmin master system. You will then
be able to create new virtual systems of the same type by instantiating
the created image.
Creating an image is an excellent way to clone a working system, or to create
a template once you have installed and configured a system to your liking.
Cloudmin will clear the root password, authorized SSH keys and any Virtualmin
license from the source system before imaging, and then set them properly
when a new system is created from the image.
Becausing imaging requires that the entire filesystem of the source be copied,
the source system may be shut down during the imaging process. Once it is
complete, it will be re-started with any changed files restored to their
original state. Depending on the speed of your network and size of the image,
the process may take 5-10 minutes.
To create an image, the following fields must be filled in :
- Unique ID for image
- Here you have two choices - either select New image and enter an
ID that is not being used yet, or Overwrite old image and choose
an image to replace from the menu. Typically, new
Cloudmin images use IDs in the format type-os-software, such as xen-centos5-lamp.
- Description for image
- In this field you should enter a human-readable description, which appears
when you select the image at system creation time.
- Version number
- If you have created several images with the same ID over time, this optional
field can be used to set a version number for the new image. If you are
running multiple Cloudmin master systems and copying images between them, a
version makes it easier to keep track of image changes.
