12.5.3 Managing the virtualization system configuration

(1) Considerations related to prerequisites

Check the types of virtualization software and virtualization environment management software and the prerequisite OSs to determine whether a virtualization system configuration can be managed.

Types of virtualization software and virtualization environment management software

To build virtual hosts, virtualization software and virtualization environment management software are required. Determine whether IM Configuration Management can manage the virtualization system configuration of your products. The following products are supported:

• Virtualization environment management software that can be used for the virtualization system management hosts:

  vCenter, JP1/SC/CM, SCVMM, and HCSM

• Virtualization software that can be used for VMM hosts:

  KVM, Hyper-V, Hitachi Compute Blade logical partitioning feature, and VMware ESX

The following table describes the available combinations of virtualization environment management software and virtualization software.

Table 12‒10: Combinations of virtualization environment management software and virtualization software

Virtualization environment management software	Virtualization software
vCenter	VMware ESX
JP1/SC/CM	Hitachi Compute Blade logical partitioning feature
SCVMM#	Hyper-V
HCSM	Hitachi Compute Blade logical partitioning feature
--	KVM

--: Unnecessary

#

When vCenter is managed by SCVMM, virtualization configuration information of vCenter and VMware ESX can be managed.

Prerequisite operating systems

The prerequisite operating system for JP1/SC/CM, vCenter, and SCVMM is Windows and it is supported by the versions of virtualization environment management software specified in the JP1/IM - Manager Release Notes.

Virtualization configuration information of virtualization software and virtualization environment management software that are running on UNIX cannot be collected.

(2) Methods of collecting virtualization configuration information

Virtualization configuration information is collected when the virtualization system configuration is changed, or when information is regularly managed. There are two methods of collecting virtualization configuration information as shown below. Consider which method is better for your environment.

Executing commands to collect virtualization configuration information

You can execute commands to collect virtualization configuration information from the virtualization software and virtualization environment management software. The commands differ depending on the types of the virtualization software and virtualization environment management software.

The following table describes the virtualization software and virtualization environment management software, and the commands you can use with specific software products.

Table 12‒11: Virtualization software, virtualization environment management software, and corresponding commands

Type of virtualization software and virtualization environment management software from which information collected	Command name	Collection range
vCenter	jcfcolvmvc	Virtualization system management host running vCenter Virtual host running VMware ESX
JP1/SC/CM	jcfcolvmvirtage	Virtual host running Hitachi Compute Blade logical partitioning feature
SCVMM#1	jcfcolvmscvmm	Virtualization system management host running SCVMM Virtual host running Hyper-V Virtual host running vCenter and VMware ESX if vCenter is managed by SCVMM
HCSM	jcfcolvmhcsm	Virtual host running Hitachi Compute Blade logical partitioning feature, and the host name#2 that can be acquired from HCSM
KVM	jcfcolvmkvm	Virtual host running KVM
VMware ESX	jcfcolvmesx	Virtual host running VMware ESX

#1: This software is available only for Windows.

#2: When collecting virtualization configuration information from hosts that are not virtual hosts running Hitachi Compute Blade logical partitioning feature, the only information you can collect is host names and host types. In addition, Unknown is always collected as the host type of the hosts from which the information is collected.

Using the IM configuration management viewer to collect virtualization configuration information

With the IM configuration management viewer, you can collect virtualization configuration information by specifying a virtualization system management host and hosts on which KVM is running. The type of the software running on the specified virtualization system management host determines the types of the virtualization software and virtualization environment management software from which information can be collected.

The following table describes the combinations of the software running on the host that collects virtualization configuration information and the virtualization software and virtualization environment management software from which the information is collected.

Table 12‒12: Relationship of virtualization system management host, virtualization software, and virtualization environment management software

Software installed on the host collecting virtualization configuration information	Software from which information collected	Collection range
vCenter	VMware ESX	Virtualization system management host running vCenter Virtual host running VMware ESX
JP1/SC/CM	Hitachi Compute Blade logical partitioning feature	Virtual host running Hitachi Compute Blade logical partitioning feature
SCVMM#1	Hyper-V vCenter#2 VMware ESX#2	Virtualization system management host running SCVMM Virtual host running Hyper-V Virtual host running vCenter and VMwareESX when vCenter is managed by SCVMM
HCSM	Hitachi Compute Blade logical partitioning feature	Virtual host running Hitachi Compute Blade logical partitioning feature, and host name#3 that can be obtained from HCSM
KVM	KVM	Virtual host running KVM

#1: This software is available only for Windows.

#2: If vCenter is managed by SCVMM, information from both vCenter and VMwareESX is collected.

#3: When collecting virtualization configuration information from hosts that are not virtual hosts running Hitachi Compute Blade logical partitioning feature, the only information you can collect is host names and host types. In addition, Unknown is always collected as the host type of the hosts from which the information is collected.

(3) Methods of monitoring virtualization configuration information in the monitoring tree of the Central Scope

Consider whether to monitor the virtualization system configuration that contains the virtual hosts running on the virtualization system management hosts and VMM hosts in the monitoring tree of the Central Scope.

The method of monitoring virtualization configuration information in the monitoring tree of the Central Scope differs depending on the collection method described in 12.5.3(2) Methods of collecting virtualization configuration information.

Executing commands to collect virtualization configuration information

Execute a command to import virtualization configuration information to the Central Scope, and apply the information to the monitoring tree.

Using the IM configuration management viewer to collect virtualization configuration information

After you collect virtualization configuration information from the IM configuration management viewer, actions such as the addition of VMM hosts and changes to virtualization configuration are applied to the virtualization configuration information. In the IM configuration management viewer, you can apply this virtualization configuration information to the monitoring tree of the Central Scope.
