7.3.1 Collecting virtualization configuration information

You can use a command or the IM Configuration Management window to collect virtualization configuration information.

The communication described for this function requires host names to be able to be resolved by the OS.

The following figure shows how virtualization configuration information is collected.

Figure 7‒16: Collection of virtualization configuration information

The flow is described below. Follow the numbers in the figure.

Perform the following to order collection of virtualization configuration information:
- On the manager, execute the command for collecting virtualization configuration.
- In the IM Configuration Management window, execute Collect Virtualization Configuration or Batch Collect Virtualization Configurations.
Collect virtualization configuration information from the following hosts:
- Virtualization system management host
- Virtual host running KVM
- Virtual host running VMware ESX

Organization of this subsection

(1) When executing a command for collecting virtualization configuration information from the manager
(2) When performing collection or batch-collection of virtualization configuration in the IM Configuration Management window

(1) When executing a command for collecting virtualization configuration information from the manager

The following table describes the supported types of virtualization software and virtualization environment management software and the corresponding command names.

Table 7‒19: Types of virtualization software and virtualization environment management software (when a command is used)
Type of virtualization software or virtualization environment management software	Command name	Scope of collection
vCenter	`jcfcolvmvc`	Virtualization system management hosts running with vCenter Virtual hosts running with VMware ESX
JP1/SC/CM	`jcfcolvmvirtage`	Virtual hosts running with Hitachi Compute Blade logical partitioning feature
SCVMM^#1	`jcfcolvmscvmm`	Virtualization system management hosts running with SCVMM Virtual hosts running with Hyper-V Virtual hosts running with vCenter and VMware ESX when vCenter is managed by SCVMM
HCSM	`jcfcolvmhcsm`	Virtual hosts running Hitachi Compute Blade logical partitioning feature and host names that can be obtained from HCSM^#2
KVM	`jcfcolvmkvm`	Virtual hosts running KVM^#3
VMware ESX	`jcfcolvmesx`	Virtual hosts running with VMware ESX

#1: Supported on Windows only.

#2: You can collect only host names and host types as the virtualization configuration information on hosts that are not virtual hosts running Hitachi Compute Blade logical partitioning feature. Also, the host type that is collected from these hosts is Unknown.

#3: When virtualization configuration information is collected from KVM, the host identification names defined in KVM are collected. (A host identification name, called a domain name in KVM, is the name that is shown as Id Name when the virsh list command is executed.) As the host name of a virtual host, specify the same name as the corresponding host identification name defined in KVM. If you change the host name of a virtual host, redefine the corresponding host identification name defined in KVM so that they are identical.

(2) When performing collection or batch-collection of virtualization configuration in the IM Configuration Management window

You can collect virtualization configuration information on the virtualization system management host and the virtual hosts running on VMM hosts.

The virtualization configuration information on virtual hosts running KVM can be collected from any host on which KVM is running. The virtualization configuration information on the virtual hosts running virtualization software other than KVM can be collected from the virtualization system management host.

The virtualization software from which information can be collected varies according to the software installed on the host that collects virtualization information. The following table describes the software installed on the host that collects virtualization information and the corresponding virtualization software from which information can be collected.

Table 7‒20: Software installed on hosts that collect information and corresponding software from which information is collected (when the IM Configuration Management window is used)
Software installed on the host collecting virtualization configuration information	Collection target	Scope of collection
vCenter	VMware ESX	Virtualization system management host running with vCenter Virtual hosts running with VMware ESX
JP1/SC/CM	Hitachi Compute Blade logical partitioning feature	Virtual hosts running with Hitachi Compute Blade logical partitioning feature
SCVMM^#1	Hyper-V vCenter^#2 VMware ESX^#2	Virtualization system management host running with SCVMM Virtual hosts running with Hyper-V Virtual hosts running with vCenter and VMware ESX when vCenter is managed by SCVMM
HCSM	Hitachi Compute Blade logical partitioning feature	Virtual hosts running Hitachi Compute Blade logical partitioning feature and host names that can be obtained from HCSM^#3
KVM	KVM	Virtual hosts running KVM^#4

#1: Supported on Windows only.

#2: vCenter and VMware ESX are collected when vCenter is managed by SCVMM.

#3: You can collect only host names and host types as the virtualization configuration information on hosts that are not virtual hosts running Hitachi Compute Blade logical partitioning feature. Also, the host type that is collected from those hosts is Unknown.

#4: When virtualization configuration information is collected from KVM, the host identification names defined in KVM are collected. (A host identification name, called a domain name in KVM, is the name that is shown as Id Name when the virsh list command is executed.) As the host name of a virtual host, specify the same name as the corresponding host identification name defined in KVM. If you change the host name of a virtual host, redefine the corresponding host identification name defined in KVM so that they are identical.
