Warning Review limit reachedYou’ve reached a temporary PR review limit under our Fair Usage Limits Policy. Next review available in: 18 minutes Limit details: You’ve used all 1 included review currently available under your plan. You completed 89 included PR reviews in the past 7 days; at that activity level, included reviews refill at 1 review per hour. Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

ConsoleHypervisorBackend 新增 requireExclusiveConsoleSessionRenewal()。独占续租后端的代理令牌会追加新的 UUID。 |
过期代理处理与失败清理 console/src/main/java/org/zstack/console/AbstractConsoleProxyBackend.java |
过期代理根据后端能力选择直接重建或先删除控制台会话。删除失败时仅在 removeVoOnFailure 为真时删除 ConsoleProxyVO。 |
续租流程集成验证 test/src/test/groovy/org/zstack/test/integration/console/ConsoleProxyCase.groovy |
新增传统续租和独占续租测试，覆盖代理重建、令牌更新、删除失败及重试行为。 |
Estimated code review effort: 3 (Moderate) | ~25 minutes
Merge Risk: ⚪ Minimal · up to 013d1
The change deletes an expired console proxy before recreating it and propagates deletion failures; no actionable merge-blocking risk remains beyond normal checks and review.

77-78: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value将
consoleMgr重命名为consoleManager。
consoleMgr使用了不必要的缩写。使用完整名称可使受保护字段和续租逻辑更清晰。根据路径指令：“不允许使用不必要的缩写……应使用完整单词提升可读性”。
建议修改
- protected ConsoleManager consoleMgr; + protected ConsoleManager consoleManager; ... - ConsoleHypervisorBackend backend = consoleMgr.getHypervisorConsoleBackend(HypervisorType.valueOf(vm.getHypervisorType())); + ConsoleHypervisorBackend backend = consoleManager.getHypervisorConsoleBackend(HypervisorType.valueOf(vm.getHypervisorType()));Also applies to: 146-146

Root Cause: DPU baremetal VNC uses a single-client x11vnc session, but the shared console renewal flow did not release the expired proxy before establishing a replacement. The stale connection could keep occupying the only VNC session and leave the newly opened console black. Solution: Let hypervisor console backends opt into exclusive-session renewal. For exclusive backends, delete the expired proxy before creating a fresh token and stop renewal when deletion fails. The default remains non-exclusive so KVM and other backends keep their existing behavior. Test: Add console integration coverage for shared renewal, exclusive renewal, and delete-failure handling. Scope simulator callbacks to the current VM so asynchronous GC retries from earlier stability iterations cannot alter counters or failure injection.

Root Cause:
When a console proxy record expired, the backend removed only the database VO and immediately established a new proxy. For DPU VNC, the old proxy session remained on the agent and conflicted with the recreated session.
Solution:
Delete the existing console session through the backend before establishing a replacement. Propagate deletion failures instead of creating another proxy on an uncleared agent session.
Test:
Added an integration case that expires a console proxy record and verifies the old proxy is deleted before a new one is established.
Verified with:
mvn package -pl console -am -DskipTests -Djacoco.skip=true
The full ./runMavenProfile premium build was attempted but did not complete because of the local build environment.
