This section explains the overcommit function for L-Servers.
Overcommit
The OVM for SPARC overcommit function for the CPU and memory is available on Resource Orchestrator.
The OVM for SPARC overcommit function for the CPU and memory allows a guest domain to use more virtual resources than that of the actual CPU and memory of a server.
Resource Orchestrator provides the following functions to utilize the OVM for SPARC overcommit function when creating L-Servers.
Setting an overcommit attribute for a resource pool
Overcommit attributes can be set for resource pools. If an L-Server template with the overcommit attribute configured is used, an L-Server with the overcommit attribute configured can be created by selecting the resource from the resource pool with overcommit configured.
Deployment of L-Servers with more resources than those of the server
Creation of an L-Server with more resources than that of the actual CPU or memory installed on a server is possible.
Whether the resulting L-Server can be started depends on the resources available on the VM host.
Installation Procedure
Create a VM Pool for Overcommit
For details on how to create a VM pool, refer to "Chapter 20 Resource Pool Operations" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
Point
Refer to the "Point" described in "1. Create a VM Pool for Overcommit" in "Installation Procedure" in "8.2.11 Overcommit".
Note
Refer to the "Note" described in "1. Create a VM Pool for Overcommit" in "Installation Procedure" in "8.2.11 Overcommit".
For details on how to edit the L-Server template, or create and check an L-Server, perform the operations of step 3 and later described in "8.2.11 Overcommit". The values that can be configured in the L-Server template or the VM specific information definition files as described in the reference differ depending on the VM types. In OVM for SPARC, the values can only be specified when configuring overcommit in the L-Server template.
