This is how the Python27.zip archive can be generated from the MSI file shipped
by CloudBase. Of course, update the URL when picking a new version.

a) On admin server:

 - edit /etc/samba/smb.conf and change the reminst share to have "read only = No"
 - execute the following:

rcsmb restart
mkdir /srv/tftpboot/msi
cd /srv/tftpboot/msi
wget https://www.cloudbase.it/downloads/HyperVNovaCompute_Juno_2014_2.msi

b) On Windows node:

 - execute the following:

net use x: \\$CROWBAR_IP\reminst
x:
cd msi
msiexec /a HyperVNovaCompute_Juno_2014_2.msi /qb TARGETDIR=x:\msi\extracted

c) On admin server:

 - execute the following:

cd /srv/tftpboot/msi/extracted/Cloudbase\ Solutions/OpenStack/Nova/Python27/
rm -rf Scripts/nova-* Scripts/neutron-* Scripts/ceilometer-* Lib/site-packages/nova Lib/site-packages/neutron Lib/site-packages/ceilometer Lib/site-packages/nova-20*.egg-info/ Lib/site-packages/neutron-20*.egg-info/ Lib/site-packages/ceilometer-20*.egg-info/
