Check whether the memory/CPU hot plug has been enabled from the VM management software if an existing VM guest is to be linked
to a virtual L-Server.
If it is not enabled, enable the setting from the VM management software. Refer to the manual for the VM management software
network device for information on how to enable the memory/CPU hot plug with the VM management software.
[Hyper-V]
When dynamic memory settings are changed from disabled to enabled, without specifying memory capacity or initial memory capacity
for the L-Server, the values for the following items of the virtual machine will be same as the memory size.
-
Initial Memory Capacity (StartupRAM)
-
Maximum Memory
When using dynamic memory or memory weight, the VM host must be either of the following.
-
Microsoft(R) Windows Server(R) 2008 R2 SP1 or later
-
Microsoft(R) Windows Server(R) 2012
SCVMM should be one of the following, either of which can manage the VM hosts.
-
System Center Virtual Machine Manager 2008 R2 SP1 or later
-
System Center 2012 Virtual Machine Manager
When dynamic memory is enabled and memory weight is specified, modification of an L-Server will fail unless the above-mentioned
VM host and SCVMM have been prepared.
[KVM]
When memory_hotplug is configured as false in a VM specific information definition file, the maximum memory size of the created
L-Server is configured with the same value as memory size.
The memory size of an active L-Server cannot be modified when memory_hotplug is "false".
* Note: The modified value is reflected on the configuration of the L-Server by periodic queries made to the VM management software.
For details on reflection of L-Server configuration by periodic queries, refer to "
".
Note
Immediately after a snapshot is restored, there may be differences between the configuration of VM guests managed by L-Server and
those managed by VM management software.
The differences in VM guest configuration are reflected on the configuration of the L-Server by periodic queries made to the VM
management software.
For details on reflection of L-Server configuration by periodic queries, refer to "
When changing the values for server redundancy for an L-Server to which a virtual machine is already allocated, the virtual machine is
not changed, only L-Server attributes are changed.
[Solaris Zones]
If the CPU's CAP value has not been set, both "Number of CPUs" and "CPU performance" must be changed when changing the CPU
settings.
17.2.2 Modifying the Basic Information
This section explains how to modify the basic information of L-Servers. Use the following procedure to modify the basic information of
L-Servers:
[Solaris Zones]
The basic information of an L-Server linked with a virtual machine on a VM host not managed with server management software cannot
be modified from the ROR console. Modify them from the global zone.
Note
-
Immediately after a snapshot is restored, there may be differences between the configuration of VM guests managed by L-Server and
those managed by VM management software.
