Packages an existing system up as an image
This command performs the complex process of converting an existing virtual system into a Cloudmin image.
It has three required parameters :
--host followed by the hostname of the system to image,
--desc followed by a description of the image,
--id followed by a new unique image ID.
The ID is typically formatted like type-os-software,
such as xen-centos6-virtualmin.
If the ID refers to an image that already exists and you want to replace it,
--overwrite paramter to the command line.
You should also use
--version followed by a version number,
to make it easier to keep track of different instances of the same image.
files created as part of the image will be copied to the default storage locations.
Typically this is just the /var/webmin/server-manager directory on the Cloudmin master.
you can use the
--storage flag followed by a storage spec to use a different location.
This is typically given in host:path format.
Creation takes several minutes, but the command will display each step in the process as it proceeds, and inform you of its final success or failure.
