Oracle Linux Virtualization Manager (OLVM) is server virtualisation management software. According to Oracle's documentation, it is used to configure, monitor and manage an Oracle Linux KVM (Kernel-based Virtual Machine) environment, with support from Oracle. The release 4.4 administration guide states that it is based on oVirt, a free open-source virtualisation solution. It is installed on the customer's own servers and is not a vendor-hosted service.
Oracle Corporation reports in its annual filings that its principal executive offices are in Austin, Texas. Because OLVM runs on premises, management data and virtual machines remain on your own infrastructure and you choose the location. Oracle is nonetheless a US company subject to US jurisdiction, including the CLOUD Act, which matters mainly for support contracts, licensing and any integration with Oracle cloud services. Data processing and GDPR arrangements need to be agreed directly with Oracle.
