Working with an installed operating system or hypervisor
When you start a partition, DPM configures partition resources and initializes the operating system or hypervisor, according to the information you supply through the New Partition or Partition Details task. After the start process completes and the partition becomes active, you can open one of the following tasks to log in to the operating system or hypervisor.
- To log in to a Linux® operating system, use the Operating System Messages task or the Integrated ASCII Console task. The Integrated ASCII Console task must be enabled through the operating system before you can use it.
- To log in to a z/VM® hypervisor that is hosting multiple Linux guests, use the Integrated 3270 Console task.
Configuring secure execution for a Linux hypervisor
If the
IBM®
Secure Execution for Linux feature is enabled on the system, you can configure a Linux
hypervisor for secure execution, which isolates and protects any guests that run on a
hypervisor by restricting host access to guest workloads and data.
- To determine whether the IBM Secure Execution for Linux feature is enabled on the system, go to the General section of the System Details task and check the values displayed for the Secure Execution field.
- To configure Linux for secure execution, see the product documentation for the Linux distribution that you are using as a hypervisor. This feature supports Linux (KVM) hypervisors.
- To determine whether the Linux hypervisor that runs on a partition is configured for secure execution, go to the General section of the Partition Details task and check the value displayed for the Secure Execution field.
Where to find more information about operating systems and hypervisors
For additional information about a specific operating system or hypervisor, see the appropriate
resource:
- For Linux distributions, see the Linux on IBM Systems topics in IBM Documentation, at: https://www.ibm.com/docs/en/linux-on-systems?topic=linuxone-library-overview
- For the z/VM hypervisor, see
the documentation for the version of z/VM that you are installing. The z/VM library is available in IBM Documentation at https://www.ibm.com/docs/en/zvmNote: DPM supports z/VM with the limitations listed in Requirements for the hypervisor or operating system, so not all z/VM functions described in the z/VM library are available for use.
- For more information about creating and using Secure Service Container partitions, see the appropriate edition of Secure Service Container User's Guide, which is available on IBM Documentation. Go to https://www.ibm.com/docs/en/systems-hardware, select IBM Z or IBM LinuxONE, then select your configuration, and click Library Overview on the navigation bar.
