Differences between Power and x86 VMs

Because of differences between Power A CPU architecture that supports IBM i, AIX, and Linux (on Power) in Skytap. and x86 The most common CPU architecture. x86 CPUs support Windows and Linux VMs in Skytap. hardware and hypervisor, some of the capabilities between Power and x86 VMs are different.

Power states for Power VMs

Power VMs can’t be suspended. This affects the way you might use some Skytap features, like copying an environment or saving an environment as a template. For more information, see Suspend isn’t supported for Power VMs.

Using IBM i on Power VMs

Each each customer IBM i Power VM A Skytap VM that is based on Power hardware. A Power VM can be considered the equivalent of an LPAR. can be configured to use a maximum of four (4) vCPUs.

Power VM settings

Some of the settings that are available through the VMware hypervisor aren’t implemented in Power hardware or are implemented differently.

Hardware settings

Enable nested virtualization – Nested virtualization isn’t supported for Power VMs.
Hardware Version – Because Power VMs don’t use the VMware hypervisor, the VMware hardware version isn’t applicable to Power VMs.
Customize UUID – The UUID of a Power VM can’t be changed.
Enable time sync – Power VMs don’t support changes to VM BIOS clock sync settings.
Change keyboard mapping – Power VMs don’t support international keyboards.
Connection type – Power VMs support only the default SRA client and the SSH additional connection type.
Copy and paste – Copy and paste requires an SSH-connected SRA browser session. To configure SSH, see Enabling SSH on a VM for use in SRA browser client sessions..

Using containers on Power VMs

Enable containers – Power VMs don’t support Docker containers or the Skytap VM Agent.

Connecting to Power VMs

Connection types – You can access Power VMs with the SRA client, with a published service (using SSH or telnet), or with a sharing portal.
SRA client – Because SRA client access is to the Power VM shell only, the SRA client toolbar doesn’t include the (Fit to Window) or (Change Resolution) options. Additionally, the (Clipboard) option is available only for SSH-connected SRA browser sessions.
