Sometimes, you already have stored the virtual machine image in
some non-Glance location -- perhaps even a location you have no
write access to -- and you want to tell Glance where this
virtual machine image is located and some metadata about it. The
add command can do this for you.
When registering an image in this way, the only difference is
that you do not use a shell redirect to stream a virtual machine
image file into Glance, but instead, you tell Glance where to
find the existing virtual machine image by setting the
location field. Below is an example of doing
this.
Let's assume that there is a virtual machine image located at
the URL
http://example.com/images/myimage.vhd. We can
register this image with Glance using the following:
$> glance --verbose add name="Some web image" disk_format=vhd container_format=ovf\
location="http://example.com/images/myimage.vhd"
Added new image with ID: 1
Returned the following metadata for the new image:
container_format => ovf
created_at => 2011-02-23T00:42:04.688890
deleted => False
deleted_at => None
disk_format => vhd
id => 1
is_public => True
location => http://example.com/images/myimage.vhd
name => Some web image
properties => {}
size => 0
status => active
updated_at => None
