ResolutionOS and application templates created by Parallels (formerly SWsoft) are usual RPM packages and may be installed on a Parallels Virtuozzo Containers hardware node using RPM installation command like this:
rpm -ihv TEMPLATE_NAME.rpm
Please note - OS templates should be cached after they are installed, application templates do not require caching.
Cache for standard OS templates can be created using 'vzpkgcache' utility.
Cache for EZ OS templates can be created using 'vzpkg' utility - 'vzpkg create cache'.
