Users can receive a ready-to-use virtual machine within 5 minutes due to automatic OS installation. In order to provide it, VMmanager uses ISOs, OS templates, and recipes. Caching servers can be used to accelerate installation as they receive OS packages faster.
Templates of popular operating systems like Debian, CentOS, and Windows Server can be used. Recipes can help with deeper OS settings and installation of third party software. Also, there are ready templates and recipes available from official ISPsystem repository. However, it is also possible to create a separate repository and link it up with VMmanager.
