Templates
Document Actions
Templates are OS images for installation into VPS. Template utilities are provided to aim in this installation.
An OS template is basically a set of packages from some Linux distribution used to populate a VPS. With OpenVZ, different distributions can co-exist on the same hardware box, so multiple OS templates are available.
An OS template cache is an OS template installed into a VPS and then packed into a gzipped tarball. Using such a cache, a new VPS can be created in a matter of minutes, if not seconds.
For information about templates and installation instructions, see this document.
