[system] Section

The system section is used to configure "system-wide" properties of the virtual machine. The list below describes the options that can be set:

cpu_affinity – Assign virtual CPU processing to a specific host CPU.

io_affinity – Assign virtual machine I/O processing to a specific host CPU.

io_cpus – Number of host CPUs reserved for virtual machine I/O processing.

machine – Specify the Alpha system model of the virtual machine.

cpu_affinity

Assign virtual CPU processing to a specific host CPU.

Syntax

[, cpu-affinity [, ... ] ]cpu_affinity = cpu-affinity

Description

This option is a comma delimited list of host CPUs (or cores) that the virtual machine is to assign to virtual CPU threads.

The virtual machine will assign affinity automatically if this option is not set.

io_affinity

Assign virtual machine I/O processing to a specific host CPU.

Syntax

[, io-affinity [, ... ] ]io_affinity = io-affinity

Description

This option accepts a comma delimited list of specific host CPUs (or cores) the virtual machine will assign to I/O processing.

If this directive is unset the virtual machine will assign affinity automatically.

io_cpus

Number of host CPUs reserved for virtual machine I/O processing.

Syntax

io_cpus = cpu-count

Description

Use this option to reserve a specific number of host CPUs (or cores) for virtual machine I/O processing.

If both and are not set, the virtual machine will automatically reserve one third of the host CPUs (or cores) for I/O processing.io_affinity io_cpus

machine

Specify the SPARC system model of the virtual machine.
