February 2026 monthly summary for ubicloud/ubicloud focusing on reliability, performance, and governance improvements across VM orchestration and deployment tooling. Delivered four key capabilities with clear business value and traceability: 1) QEMU VM headless operation reliability and cloud-aligned reboot behavior - Removed the no-reboot option to align internal VM shutdown/reboot with cloud hypervisors; updated headless tests to verify -vga none is present in the generated QEMU command line for robust headless operation. Commits: f43620c40fa161c0dd9ea106de7ec421b007f94e; d4f3f22e6b99831fe4a0952debd18154b634fb10 2) Dynamic CPU topology optimization for AMD in QEMU - Implemented runtime CPU vendor detection (via lscpu) and enabled topoext on AMD hosts, exposing correct CPU topology while preserving existing config on non-AMD hosts. This improves performance, licensing/compatibility, and monitoring accuracy. Commit: 6e2ec1e5e91902fa5ae3ca097a1fb6e966fb98df 3) Rhizome Installation Tracking and Persistence - Introduced RhizomeInstallation model and database table to persist installation metadata (target folder, 8-char commit hash, 24-char digest, and installed_at timestamp) with admin/test coverage for visibility and governance. Commits: b68317e942252d7f5d7a0362fcfe23090351ffd9; 34132e4ba4c2cc87d16cb0ae0721f8448201240d; 160e4d20df6b1ba24e0267b9579618f7222a8bbb 4) Codebase Version Hash Exposure Across Environments - Added a centralized mechanism to expose the current git commit hash (8-char short hash) across environments (web, monitor, respirate) via GIT_COMMIT_HASH with loader/config integration for consistent traceability. Commit: a2a9ae2b12a01f76dc0c0b4fec28dcfbe913b435 Business value and impact: - Increased reliability of headless VM operations, reducing outages due to misconfigured VMs. - Improved performance visibility and correctness on AMD hardware by aligning CPU topology exposure. - Enhanced installation governance and auditability through persistent Rhizome installation records. - Stronger cross-environment traceability enabling faster debugging and compliance reporting.

Monthly summary for 2025-12 focusing on business value and technical achievements. The primary delivery this month was the GPU VM Access Information View in the ubicloud/ubicloud repository, which replaces hidden UI with an informative static view for users without the gpu_vm feature flag. This change improves user onboarding, reduces confusion, and directs users to a clear process to request access via support channels. The update aligns with feature flag gating while preserving a path to enable GPU VMs for eligible users. Impact: - Enhanced user experience: Users are informed about GPU VM availability and the steps to obtain access, reducing frustration and support inquiries. - Product gating preserved: Keeps feature flag semantics intact while offering a transparent alternative for non-enabled projects. - Traceable changes: Implementation anchored by a commit that explicitly stops hiding the Create GPU VM option and routes to a static informational view. Technologies/skills demonstrated: - Feature flag gating logic and UI routing adjustments - UX/content strategy for feature discovery and access requests - Code discipline for non-breaking UI changes and clear user guidance.

Month: 2025-11 for ubicloud/ubicloud. Delivered GPU Partitions Management and Virtualization Resource Enhancements alongside Monitoring Reliability Improvements. Implemented a GPU partition model (gpu_partition and gpu_partitions_pci_devices) with associations to VM hosts and VMs, integrated GPU partitions lifecycle with NVIDIA Fabric Manager (activate before VM start, deactivate on destruction), and extended the allocator to automatically assign partitions that match VM requirements while avoiding overlaps. Enabled provisioning of configurations with 1/2/4/8 GPUs. Refined QEMU systemd unit generation and PCI device layout (including x-no-mmap handling, /opt/fw/QEMU.fd usage, deterministic bus/addr/rombar params, and support for custom QEMU binaries and empty ROMs). Added detachment of GPU partitions upon VM destruction. Monitoring: capped checkup semaphore increments to prevent buildup and extended host unavailability alert delay from 45s to 90s to reduce noise. Overall, these changes improve resource isolation, scalability for GPU-heavy workloads, boot performance, and operator reliability, delivering measurable business value in hosted GPU-capable workloads and operational stability.

In 2025-10, Ubicloud delivered a suite of GPU virtualization enhancements, location visibility controls, expanded geographic coverage with Istanbul, GPU VM lifecycle improvements, and strengthened AI inference routing and billing. These efforts improved hardware compatibility, operational safety, and monetization accuracy while enabling more predictable, scalable deployments across customers and regions. Key outcomes include improved hardware support for NVIDIA B200 GPUs, robust visibility controls to prevent leakage or misconfiguration, expanded Istanbul locations with updated billing rates, updated GPU VM boot images with GPU caps to ensure fair resource allocation, and enhanced inference routing with consistent billing for AI models and predefined access controls. Reliability hardening also reduced operational risk through SSH session cleanup on event loop failures and guards against feature flag resets. Overall impact: faster, more reliable GPU-enabled workloads, clearer location-based policies, and tighter monetization controls, enabling cleaner onboarding of new regions and models while lowering support overhead.

September 2025 delivered two core capabilities in ubiCloud/ubicloud: scalable archive data management and hardened monitoring. Implemented a database partition migration for archived records to optimize storage and data organization by dropping July and August 2025 partitions and creating new partitions for September 2026 and October 2026. Improved monitoring reliability and alerting by introducing a 45-second delay before host unavailability pages, adding a retry when the last pulse is not set, and shutting down broken SSH connections during pulse checks to prevent resource leaks. These changes reduce alert noise, improve fault tolerance, and lower systemic risk across production hosts.
