Yeah, exactly.  Most CloudStack users will not build from source, and they rationally expect
some statement of Linux distro (for KVM) that is required.   They just need to know what ISOs
they can boot the hypervisor host from and expect CloudStack to manage the host.

For Ubuntu, I'd personally be fine with only supporting 12.04, but then we should have a procedure
that tells people running CS 3.0.2 with ubuntu 10.04 how to upgrade to CS 4.0 with Ubuntu
12.04 with minimal downtime.  Same for RHEL/CentOS at 6.2+.
