Configuring Your Domains to Maximize the Performance of Your Virtual Network

In previous versions of Oracle VM Server for SPARC and the Oracle Solaris OS, you could improve your network performance by configuring jumbo frames. This configuration is no longer required and unless required for another reason, using the standard MTU value of 1500 for your service and guest domains is best.

To achieve the improved networking performance, set the extended-mapin-space property to on for the service domain and the guest domains. This is the default behavior. 

primary# ldm set-domain extended-mapin-space=on domain-name

To check the extended-mapin-space property value, run the following command: 

primary# ldm list -l domain-name |grep extended-mapin
extended-mapin-space=on

Note:

A change to the extended-mapin-space property value triggers a delayed reconfiguration on the primary domain. This situation requires a primary domain reboot. You also must first stop the guest domains before you change this property value.
