Guys I gave up on the official guide. I used the scripts of dimtdv instead:

https://github.com/dimtdv/folsom-single-node/blob/master/README.md

They do not work out of the box. There are some requirements first:

1) Setup folsom repo:

cat /etc/apt/sources.list.d/folsom.list

Openstack folsom repositor

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom main

2) # apt-get install ntp

/etc/ntp.conf: server ntp.ubuntu.com iburst server 127.127.1.0 fudge 127.127.1.0 stratum 10

3) # apt-get install git

4) # git clone https://github.com/dimtdv/folsom-single-node.git

# cd folsom-single-node.git

5) Setup lvm2

apt-get install lvm2

Create a volume group named "nova-volumes" (This is optional but recommended in a production environment. If you skip this a normal file will be created to represent the Volume Group pgysical volume)

6) Setup networking as per README.md

7) Run these scripts after you setup stackrc:

./install-mysql.sh

./install-keystone.sh

./init-keystone.sh

./install-glance.sh

./init-glance.sh

./install-nova.sh

./install-dash.sh

./restart-nova.sh

8) mkdir -p /var/lib/dash/.blackhole

9) login ar http://youserver.dom/horizon

Enjoy!
