The installation of an OS contained entirely within another OS installation is described as a guest. A guest is a term that refers to a virtual machine (VM) that runs on top of a host operating system (OS) using a hypervisor or a virtualization software. A guest can have a different OS than the host, and can run multiple applications or services independently from the host. A guest can also be isolated from the host and other guests for security or testing purposes.

The server is infected with a virus and SELinux is enabled on the server are most likely causing the issue of unauthorized services running on the server. A virus is a type of malicious software that infects a system and performs unwanted or harmful actions, such as creating, modifying, deleting, or executing files. A virus can also create backdoors or open ports on a system to allow remote access or communication with external sites. SELinux (Security-Enhanced Linux) is a security module for Linux systems that enforces mandatory access control policies on processes and files. SELinux can prevent unauthorized services from running on a server by restricting their access to resources based on their security context. However, SELinux can also cause problems if it is not configured properly or if it conflicts with other security tools.

Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines.
