+# Source: Ovirt
+
+## Installation
+
+The SDK is optional: installations using other sources do not need it. Selecting
+an oVirt source without the SDK logs an error and skips that source.
+
+On Debian/Ubuntu, install the SDK's build dependencies before installing Python
+packages:
+
+```sh
+sudo apt-get install gcc python3-dev libxml2-dev libcurl4-openssl-dev
+pip install -r requirements-ovirt.txt
+```
+
+With uv, use `uv sync --extra ovirt` after installing the native libraries.
+The SDK contains a native extension; a compiler and Python development headers
+matching your Python version are needed when no wheel is available. The runtime
+needs libxml2 and libcurl.
+
+For Docker, enable the optional source in both build stages:
+
+```sh
+docker build --build-arg INSTALL_OVIRT=true -t netbox-sync:ovirt .
+```
+
+## Configuration
+
+```ini
+[source/production-ovirt]
+type = ovirt
+url = https://engine.example.com/ovirt-engine/api
+username = inventory@internal
+password = replace-me
+validate_tls_certs = True
+ca_file = /etc/pki/ovirt-engine/ca.pem
+permitted_subnets = 10.0.0.0/8, fd00::/8
+cluster_site_relation = DC/Production = Main Site
+```
+
+Use an account with read access to datacenters, clusters, hosts, VMs, disks,
+interfaces, and reported devices. The existing source options remain supported,
+including name filters, site/tenant/role/tag relations, domain stripping,
+`set_vm_name_to_uuid`, `skip_vm_comments`, `skip_vm_platform`, and
+`host_custom_object_attributes` / `vm_custom_object_attributes` (dot-separated
+SDK attribute paths). Generate a full example with `python netbox-sync.py -g`.
+
+Guest IP discovery requires the guest agent to report network devices. VMs
+without agent data still receive their configured interfaces and disks. As with
+other sources, bare guest IPs need a matching prefix in NetBox to determine their
+prefix length. Only addresses allowed by `permitted_subnets` are imported.
+`ip_tenant_inheritance_order`, `preserve_primary_ips`, `skip_fhrp_group_ips`, and
+interface exclusion filters use the current shared network-sync behavior.
+
+NetBox 4.2+ cluster sites use scoped relations and interfaces use MAC address
+objects. NetBox 3.7+ disks are separate virtual disk objects, with the size units
+appropriate to the NetBox version. Older versions retain aggregate VM disk size.
+Missing CPU or disk size data is not replaced with fabricated values.
+
+Begin with a dry run (`python netbox-sync.py -n`) and inspect the log before
+allowing writes. Unit tests use a fake SDK and the real in-memory NetBox
+inventory; they do not replace validation against your live oVirt Engine.
