OpenStack Compute (nova)

How to store images into SWIFT from NOVA

Asked by Hugo Kou

Hello~

I have 2 computer :

1.NOVA installed
2.SWIFT installed

but I don't have any idea how NOVA(172.16.1.18) get instance image from SWIFT(172.16.1.20).

my purpose is making a similar enviroment with eucalyptus(walrus) or EC2(S3)

I added a flag into nova-manage.conf like this
--s3_host=172.16.1.20

how can I reach my desire?

Ah, this is more a question for nova. I'll see if I can get this question moved over there.

Project glance is what you are asking for -- https://blueprints.launchpad.net/glance

But note that swift is 'cold storage' system. So, images will be stored there - but they are not suitable for running virtual guests with it.

For reliable nova storage solution you should look at sheepdog support, thats probably one of best solutions:

Thanks David Pravec and gholt,

May I ask a question about Glance, is there have installaton and user guide for Glance? Or Glance still a bluesprint, dose it work in AustinRelease?

Hugo: glance project should have working code. I didnt test it, but its experimental version is (optionally) available in austin release.

Look here for glance page on launchpad: https://launchpad.net/glance
There is some documentation in the code, but not much.
Probably best for you is asking online on IRC channel -- irc://freenode.net/#openstack

Hi Hugo!

We're currently working heavily on Glance. Expect Swifit to be usable from Nova as the image store for the Bexar release (next release).

We'll have docs up by then too :)
