Changing Virtual L-Server Specifications
The following items can be changed when the power status of the virtual L-Server is ON. For details, refer to the manuals of VM
products.
-
CPU Performance
-
Number of CPUs
-
Memory Size
-
OS Type (When no images are not deployed)
[OVM for x86]
The OS type cannot be changed, regardless of whether images are deployed or not.
[KVM]
When changing the specifications for the OS types (when images have not been deployed) of virtual L-Servers, for KVM it is
necessary to perform settings based on the OS type that the user intends to install.
When the OS type differs from the OS installed on the virtual L-Server, operation is not guaranteed.
The following shows the VM products where changes may be made while the power is on:
-
VMware
-
Hyper-V
-
KVM
The items that can be changed depend on the type of VM product and the settings. Refer to
while the power is on" for details.

*1: Can be changed if memory/CPU hot plug is enabled. The memory/CPU hot plug is enabled on the virtual L-Server created by
Resource Orchestrator.
*2: The changed value will be enabled on the actual virtual machine after it is restarted.
[VMware] [Hyper-V]
When CPU reserve, memory reserve, and initial memory capacity have been set for the L-Server, changing the CPU performance and
memory size to values smaller than those values is not possible. To change these settings, use the command-line or VM management
software. (*)
[VMware]
When the memory size is changed, the limit value of memory is also changed.
However, when the limit value of memory has been set to "Unlimited", only the memory size is changed.
When changing the memory limit setting, use the VM management software to do so. (*)
For details on the configuration method, refer to the manual of the VM management software.
When VMware FT has been configured on a virtual machine linked with a virtual L-Server, server redundancy settings cannot be
modified.
