Take the 2-minute tour ×  I am using the latest Desktop Ubuntu
Narwhal as a redundant load balancer. This setup also needs
keepalived and Crossroads XR.  This works great but now I would
like to produce this as an appliance so that it is easy to
deploy.  What would be the correct way to approach this
requirement?  share|improve this question  1 Answer 1  I would
have a couple of recommendations, the first being on the
security side;    1. Goto http://www.cisecurity.org/ and
download the security guide for Debian and ensure the system has
been hardened according to the guide.    2. For physical
systems, goto http://www.geekconnection.org/remastersys to
create a customized version of Ubuntu based on your build
requirements(development of remastersys stopped).    3. For
virtualization I would create both a VMWare and OVF
(Virtualbox).  Hope this helps.  share|improve this answer What
is your intention with step 2 for physical systems? Create a
bootable live cd of the hardened installation? –  Pro Backup Feb
