This option enables Nova, also known as OpenStack Compute,
|
|
a cloud computing system, as a single-machine
|
|
installation. That is, all of Nova's components are
|
|
enabled on this machine, using SQLite as Nova's database.
|
|
This is useful for evaluating and experimenting with Nova.
|
|
However, for a real cloud computing environment, you'll
|
|
want to enable some of Nova's services on other machines,
|
|
and use a database such as MySQL.
