Glance

Glance is a component of OpenStack that allows you to manage virtual machine images. It does have relatively good documentation available at http://glance.openstack.org/.

To install glance, follow these steps:

root # emerge glance
root # rc-update add glance-api default
root # rc

This will start glance-registry, the actual repository service, as well as glance-api, which allows remote access to the repository via the Glance API.

To see if you can properly connect to the Glance API, use the glance index command, which should show an index of virtual machine images currently being stored. Since this is a brand-new install, this list should be empty:

root # glance index
root #

A virtual machine image can be added to Glance as follows:

root # glance add name="Zenoss 3.2.1 VMWare Linux 64-bit" is_public=true container_format=bare disk_format=vmdk < zenoss-3.2.1.zip 
========================================================================[100%] 225.027803M/s, ETA  0h  0m  0s
root #

Once added, it will now show up in the index:

root # glance index
ID                                   Name                           Disk Format          Container Format     Size
