What is oVirt?

A virtualization manager coasting on backports, with releases years apart

oVirt Engine's release feed is sparse and slowing: 4.5.5 in late 2023, 4.5.6 and a pair of 4.5.3.x backports in early 2024, then nothing until 4.5.7 in December 2025. Almost every entry is a list of targeted fixes and backports rather than features — OVF import edge cases, template handling, NVRAM save/restore logic, CA generation as a non-root user, Keycloak group handling. One CVE, CVE-2024-0822, appears in 4.5.6 and its 4.5.3 backport.

What is SigNoz?

SigNoz makes LLM traces readable with a conversation-style Thread view.

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

◆ Current state

oVirt Engine's release feed is sparse and slowing: 4.5.5 in late 2023, 4.5.6 and a pair of 4.5.3.x backports in early 2024, then nothing until 4.5.7 in December 2025. Almost every entry is a list of targeted fixes and backports rather than features — OVF import edge cases, template handling, NVRAM save/restore logic, CA generation as a non-root user, Keycloak group handling. One CVE, CVE-2024-0822, appears in 4.5.6 and its 4.5.3 backport.

◆ Where it's heading

This reads as a mature platform in maintenance rather than one being developed. The parallel 4.5.3.x stream exists purely to carry fixes back to deployments that cannot move, and the two-year gap between 4.5.6 and 4.5.7 says more about the project's momentum than any individual change does. Nothing in these entries points toward new capability.

◆ Prediction

The entries do not support a confident call on where this goes next; the only observable pattern is long gaps punctuated by accumulated fix rollups, so another such rollup is the most that can be inferred.

5.0

SigNoz makes LLM traces readable with a conversation-style Thread view.

◆ Current state

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

◆ Where it's heading

SigNoz is moving into LLM observability from both sides: August's plugin put it inside AI coding agents, and the Thread view now makes it a place to debug AI apps. Underneath, the alerting API keeps migrating on fixed, repeatedly announced dates. Alert channels into incident tools fill out the operational side.

◆ Prediction

Expect more AI-specific views on top of the Thread view, such as token or cost breakdowns per conversation, and the v1 rules removal to ship on November 11 as announced.
