You have a Windows Server container host named Server1.

ProcessA : All the containers and Server1

ProcessB : Container3 and Server1 only

Comprehensive and Detailed Explanation with all Administering Windows Server Hybrid Core Infrastructure documents : =

Understand ing the visibility of processes within Windows Server containers depends entirely on the isolation mode used: Windows Server isolation (Process isolation) or Hyper-V isolation . According to official documents for Administering Windows Server Hybrid Core In frastructure, these two modes determine how the container ' s kernel and processes interact with the host system.

Windows Server Isolation (Process Isolation) : In this mode, containers share the same kernel as the host. Processes running inside the container are essentially standard processes on the host, albeit isolated through namespaces and resource controls. Consequently, a process running in a process-isolated container (like Container1 and Container2 in the exhibit) is visible from the host ' s Task Manag er or Get-Process command, as well as from other containers sharing the same host kernel. Therefore, ProcessA can be verified as running from All the containers and Server1 .

Hyper-V Isolation : This mode provides a more secure and isolated environment by ru nning each container inside its own highly optimized virtual machine (utility VM). Because each container has its own private kernel, the host cannot " see " the internal processes of the container, and containers cannot see into each other. Container3 uses Hyper-V isolation. Therefore, ProcessC is only visible to the internal operating system of Container3 and, at a management level, to Server1 (the host). It is invisible to other containers (Container1, 2, and 4) because they are separated by kernel-level boundaries. Thus, you can verify ProcessC on Container3 and Server1 only .
