Glance Image Store

The Glance project provides services for discovering, registering, and retrieving virtual machine images. Glance has a RESTful API that allows querying of VM image metadata as well as retrieval of the actual image.

Usage

Import new public image

glance image-create --name 'Windows 7 x86_64' --is-public true --container-format bare --disk-format qcow2  < ./win7.qcow2

Change new image's disk properties

glance image-update "Windows 7 x86_64" --property hw_disk_bus=ide

Change new image's NIC properties

glance image-update "Windows 7 x86_64" --property hw_vif_model=rtl8139

Documentation and Bugs

To learn how to deploy OpenStack Salt, consult the documentation available online at:

https://wiki.openstack.org/wiki/OpenStackSalt

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

http://bugs.launchpad.net/openstack-salt

Developers wishing to work on the OpenStack Salt project should always base their work on the latest formulas code, available from the master GIT repository at:

https://git.openstack.org/cgit/openstack/salt-formula-glance

Developers should also join the discussion on the IRC list, at:
