The Quantum integration with Horizon needs some work.  Most importantly, it
doesn't play nicely with Quantum Manager.  We've been looking for
volunteers to get it in good shape again.  Would love to make progress on
this in E-4 if anyone is interested (hint, hint!)

You can do this by creating project specific networks with "nova-manage
network create" and passing a --project_id flag that specifies the integer
ID for the project (note: the docs indicate that this project_id can be a
string, but that is no longer the case.  This was a recently discovered bug
and we will be updating the docs for essex-3).   Note: you will also need
to prevent stack.sh from creating its default network (or delete it
afterward), since this network has no project specified and is thus a
global network that all VMs will get a NIC on.

See the Quantum Admin Guide for more details on creating private and global
