5.5.5 Change Memory Settings of Virtual Server
Function
This plug-in can be used to change the memory settings of virtual servers in a Hyper-V environment.
This plug-in requires the following servers:
- Hyper-V server (execution-target server)
A server on which Hyper-V is installed
- Virtual server
A virtual server managed by Hyper-V
This plug-in can be used to change the following memory settings:
- Startup RAM (MB)
- Whether to enable dynamic memory
- Minimum RAM for dynamic memory (MB)
- Maximum RAM for dynamic memory (MB)
- Buffer for dynamic memory
- Memory weight
- Maximum size of the memory available on a NUMA node (MB)
Use situation
This plug-in can be used to change the memory settings of a virtual server.
Prerequisites
For the most recent support statuses for the prerequisite products in the system, the prerequisite products on the execution-target server, and the OSs for the prerequisite products on the execution-target server, see the Release Notes.
Prerequisite products in the system:
JP1/Automatic Operation 11-00 or later
Prerequisite products on the execution-target server:
(1) Prerequisite products on the Hyper-V server
- Windows Server 2012 Hyper-V, Windows Server 2012 R2 Hyper-V
(2) Prerequisite OS for the virtual server
- Windows Server 2008 R2 Standard/Enterprise/Datacenter
- Windows Server 2012 Standard/Datacenter, Windows Server 2012 R2 Standard/Datacenter
Environments where Server Core is installed are excluded.
OSs for the prerequisite products on the execution-target server:
- Windows Server 2012 Standard/Datacenter or Windows Server 2012 R2 Standard/Datacenter
Environments where Server Core is installed are excluded.
Condition for using the prerequisite products on the execution-target server:
(1) Each virtual server name must be unique within a single Hyper-V server.
Cautions
(1) The memory settings that can be changed differ depending on the status of the virtual server.
(2) If all memory settings are blank, an error occurs.
