Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.
“VirtualBox for production server virtualization: it is a free Type 2 hypervisor, which makes it more appropriate for desktop/test use than for production server infrastructure.” Perplexity Sonar · Server virtualization · negative prompt · hard negative
“deprecated for enterprise (e.g., avoid VirtualBox for servers—it's desktop-oriented)” Grok 4.1 Fast · Server virtualization · negative prompt · hard negative
“widely used for development, testing and lab environments rather than production-scale VDI” Muse Glimmer 30B · Virtual desktops · budget prompt · soft negative
“VirtualBox 6.1 and 7.0 are both end-of-life and no longer receive security patches” MiniMax M2.5 · Server virtualization · negative prompt · soft negative
Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 24 of the 25 answers that named VirtualBox and are not a share of its labels.
No domain is on file for VirtualBox, so its own site is not marked.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.
An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

A new claim receives the current edition's vendor brief for VirtualBox by email, built from the raw record of the edition. It shows:
