Virtual Machine CPU Configuration Fields

Field Description

Number of

CPU

Configure the number of CPUs attached to the virtual machine. Not all virtual SPARC systems support the

configuration of multiple CPUs. For those virtual systems that do support multiple CPUs, they can still be

restricted by the formula:

Physical CPUs = Virtual CPUs + 1

An attempt to configure more virtual CPUs than allowed will result in the following error message:

Runtime

Optimization

This option controls the Dynamic Instruction Translation (DIT). This option is on by default.

CPU binding

Assign specific host CPUs to the processing of SPARC instructions.

This field is a comma-delimited list of CPU IDs. Leaving this blank will cause the virtual machine software to

assign affinity itself.

I/O binding

Assign specific host CPUs to the processing of virtual machine I/O requests.

This field is a comma-delimited list of CPU IDs. Leaving this blank will cause the virtual machine to assign I/O

processing affinity itself.

Reserved

I/O CPUs

Reserve a number of CPUs on the host system for the purpose of processing virtual machine I/O requests.

Memory Configuration

To view or change the current virtual machine memory configuration, select in the column of the left-hand pane.Memory Device

If neither and are not set, then the virtual machine software willI/O binding Reserved I/O CPUs

assign 1/3 (rounded down) of the host CPUs to I/O processing.
