Overview of Power VM hardware and guest OS settings

The Hardware tab on the VM Settings page displays information about the current VM Virtual Machine – A virtual computer or server hosted within a data center. A VM runs a full operating system and applications. Each VM has virtual resources, including CPU, RAM, file system storage, CD/DVD drive, and network interfaces. settings. You can also edit many of the VM settings from this page.

Virtual machine hardware settings determine the amount of Metered RAM A unit of measurement used to calculate VM usage, based on the amount of RAM (in GB) for a VM. To learn more, see How usage is calculated. and storage The amount of data storage space used by assets, environments, and templates. that the VM consumes. Larger VMs consume more Metered RAM and storage space. For information about how Metered RAM and storage are calculated, see Usage overview.

VM Hardware Settings

To change the Power VM CPU and RAM settings

Make sure the VM is fully powered off.
Before making hardware changes to your VM, create a template of it. If any problems occur, you can restore your VM from this template A read-only copy of an environment that can be used to back up critical environments. It acts like a blueprint for new environments. To learn more, see Saving an environment as a template. .
Navigate to the VM Settings > Hardware page.

Show me how
1. Navigate to the environment that contains the VM you want to edit.
2. Click (Settings).
  
  If the Settings button isn’t visible, you don’t have permission to edit the VM settings. Work with your instructor or Skytap administrator to edit these settings.
3. The VM Settings page displays. Click the Hardware tab.
Next to CPUs, select the number of CPUs for the VM.
Notes
- The maximum number of CPUs for a single VM varies, depending on region.
- The maximum number of CPUs for an IBM i VM is 4.
- Only valid CPU configuration options are displayed.
Next to RAM, enter between 1024 MB (2048 MB for AIX) and 256 GB of RAM.
Notes
- The minimum supported RAM for a single AIX VM is 2048 MB (2 GB).
- The maximum amount of RAM available for a VM may vary, depending on region.
Click Save.

Additional Hardware and guest OS

Guest OS – Tells the underlying host which operating system the VM is running. Power A CPU architecture that supports IBM i, AIX, and Linux (on Power) in Skytap. VMs can use one of the following Guest OS An operating system running on a VM. This functions like an operating system running on a physical machine. :

AIX (default)
IBM i
Other Linux
Red Hat Enterprise Linux
SUSE Enterprise Linux Server
Ubuntu Linux

Metered RAM – Displays the amount of Metered RAM your VM uses. For information about how Metered RAM is calculated, see Usage overview.

Disks (GB) – Displays the VM virtual disk storage settings. A virtual disk for a Power VM can be any size between 2 GB - 2 TB. A Power VM can have up to 15 virtual disks.

Skytap allocates storage in binary units (GB). However, storage is labeled as GB in the Skytap interface and API. For example, if you create a 10 GB disk for a VM, the disk has 10,737,418,240 bytes of storage within your VM (10 GB).
