To learn more about Cloud IaaS offerings, I painlessly setup Cloudstack, from Citrix, on two (outdated and defunct) DELL Optiplex 740 desktop computers.
Each desktop is configured with 8GB of memory and the processors are VT compatible (meaning they can run virtualization technology software – a hypervisor).
At first attempt, the Cloudstack software would not recognize the internal disk drives. Thinking that my old hardware would not run cloudstack, I researched the non-descript error and decided that the installer was not able to detect the disks because of the pre-existing software installed.
