Setting_up_Openstack
Back to presentations / demo portal
These are complete end-to-end instruction on how to setup openstack on a Fresh Fedora 17 system, for use in demoing Aeolus
Openstack can be run in a vm or baremetal, it cannot be run off a live cd though.
Openstack does not require too much in terms of resources, but for my vm I dedicated 1 CPU w/ 2GB of memory and 20GB of disk
