März 2026 * * ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 3 Minuten Lesedauer The CMDB CI Class Models app adds or updates classes for Red Hat Virtualization (RHV) OLVM or RHV. CMDB CI Class Models is a ServiceNow Store app that adds class models that extend the CMDB class hierarchy. The new or updated classes include class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software. Starting with version 1.28.0, Discovery and Service Mapping Patterns supports both OLVM and RHV discovery. For more information, see [Oracle Linux Virtualization Manager and Red Hat Virtualization discovery](https://www.servicenow.com/docs/access?context=red-hat-virtualization-discovery&version=australia&pubname=australia-it-operations-management&ft:locale=en-US). The RHV patterns, tables, and related items have been renamed to oVirt. See the [full release notes for all CMDB CI Class Models](https://www.servicenow.com/docs/bundle/store-release-notes/page/release-notes/store/it-operations-management/store-rn-itom-cmdb-class-models.html?emcs_t=S2h8ZW1haWx8Ym9hcmRfc3Vic2NyaXB0aW9ufE1FMlVTSFREVDc3S0hTfDMzNDcxMjV8U1VCU0NSSVBUSU9OU3xoSw). ## Request apps on the Store {#cmdb-ci-class-models-redhat-rhv__section_wht_1m2_ylb} Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://docs.servicenow.com/bundle/store-release-notes/page/release-notes/store/sn-store-release-notes.html).{#cmdb-ci-class-models-redhat-rhv__inline-send-to-store} ## Red Hat Virtualization (RHV) {#cmdb-ci-class-models-redhat-rhv__section_ppv_q25_mjb} Red Hat Virtualization (RHV) is a virtualization product that is based on the Kernel-based Virtual Machine (KVM) hypervisor. RHV uses the SPICE protocol and Virtual Desktop Server Manager (VDSM) with a RHEL-based centralized management server. The RHV solution is based on two primary software components: Red Hat Virtualization Manager (RHV-M) and Red Hat Virtualization Hypervisors or hosts: Red Hat Enterprise Linux or RHV Host (RHV-H). Hinweis: The Discovery application uses patterns to find RHV components. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. For more information, see [Oracle Linux Virtualization Manager and Red Hat Virtualization discovery](https://www.servicenow.com/docs/access?context=red-hat-virtualization-discovery&version=australia&pubname=australia-it-operations-management&ft:locale=en-US) Abbildung : 1. RHV classes integrated with the CMDB class hierarchy ## Classes {#cmdb-ci-class-models-redhat-rhv__section_evf_m4v_phb} This section lists the classes that the CMDB CI Class Models app adds or updates. See the class columns table for further details about the columns added for each class. CMDB CI Class Models: Release 1.8.0 adds the following classes for RHV. For the list of classes in the base system, including classes that this app might extend, see [CMDB tables descriptions](https://servicenow-prod.fluidtopics.net/4cOwgEVj_nQ7LgaXZkKfwQ "List of tables in the CMDB in a base system with its name, label, and a description of the type of information that is stored in the table.").{#cmdb-ci-class-models-redhat-rhv__table_ghd_qtj_tkb__entry__3} | Class | Extends | Description | |-|-|-| | RHV LDC \[cmdb_ci_rhv_ldc\] | Logical Datacenter \[cmdb_ci_logical_datacenter\] | RHV logical datacenter. | | RHV Datacenter \[cmdb_ci_rhv_datacenter\] This class is deleted. | N/A | N/A | [ ] {#cmdb-ci-class-models-redhat-rhv__table_ghd_qtj_tkb} CMDB CI Class Models: Release 1.6.0 adds the following classes for RHV.{#cmdb-ci-class-models-redhat-rhv__table_x53_n4v_phb__entry__3} | Class | Extends | Description | |-|-|-| | RHV Server \[cmdb_ci_rhv_server\] | Virtualization Server \[cmdb_ci_virtualization_server\] | The RHV virtualization host. | | RHV Object \[cmdb_ci_rhv_object\] | Virtual Machine Object \[cmdb_ci_vm_object\] | A base class for other classes to derive from. | | RHV Manager \[cmdb_ci_rhv_manager\] | Application \[cmdb_ci_appl\] | RHV Manager instance. | | RHV Cluster \[cmdb_ci_rhv_cluster\] | RHV Object \[cmdb_ci_rhv_object\] | RHV cluster. | | RHV Datacenter \[cmdb_ci_rhv_datacenter\] Hinweis: This class is being deleted in the CMDB CI Class Models 1.6.0 release. | RHV Object \[cmdb_ci_rhv_object\] | RHV datacenter. | | RHV Virtual Machine Instance \[cmdb_ci_rhv_vm_instance\] | Virtual Machine Instance \[cmdb_ci_vm_instance\] | RHV virtual machine instance. | [ ] {#cmdb-ci-class-models-redhat-rhv__table_x53_n4v_phb} ## Class columns {#cmdb-ci-class-models-redhat-rhv__section_zl1_3ws_rkb} CMDB CI Class Models: Release 1.6.0 adds the following columns to the respective classes. {#cmdb-ci-class-models-redhat-rhv__table_wl5_dzm_m3b__entry__2} | Added columns | Description | |-|-| | url | URL used to access the object. | [Tabelle : 1.
