How to register an image in openstack

After having installed and configured the worker and controller nodes of the openstack testbed we would like to upload images into it.

First I downloaded some images to /root/images on controller node. One is from Xin and another one is a minimal image for testing I got from the net. I have no idea what are they worth.


Then I tried to follow the instructions

http://docs.openstack.org/cactus/openstack-compute/admin/content/part-ii-getting-virtual-machines.html

which go like this:

image="ubuntu1010-UEC-localuser-image.tar.gz"
wget http://c0179148.cdn1.cloudfiles.rackspacecloud.com/ubuntu1010-UEC-localuser-image.tar.gz
uec-publish-tarball $image [bucket-name] [hardware-arch]

and I could not find where does the

uec-publish-tarball

command comes from. Finally I realized that it comes from Ubuntu and the manual became Ubuntu specific without saying it explicitly.


So I tried different approach.

cd /root/images

glance add name="My Image" < sl61-kvm.tar.bz2 # the image I got from Xin

The command responded that the image got Id=1, which is a good sign.

Then I did:

glance show 1

and got:

URI: http://0.0.0.0/images/1
Id: 1
Public: No
Name: My Image
Size: 199737477
Location: file:///var/lib/glance/images/1
Disk format: raw
Container format: ovf

Which suggests that the file is in the system. But when I tried:

glance index

it said:

no public images found

So I tried to register it again:

glance add name="My Image" is_public=true < sl61-kvm.tar.bz2
Added new image with ID: 2

I tried to list:

glance index
Found 1 public images...
ID Name Disk Format Container Format Size
---------------- ------------------------------ -------------------- -------------------- --------------
2 My Image raw ovf 199737477

So it seems we have uploaded an image to the system.


Now I have to figure out how to run it.
