This guide splits it across two Sparks with vLLM tensor parallelism over RoCE, reaches 51 tokens per second, and connects OpenAI’s Codex CLI as a fully local coding agent.https://blog.5glinux.com/posts/wso2-dbaas-suse-virtualization/Wed, 14 Oct 2026 00:00:00 +0000https://blog.5glinux.com/posts/wso2-dbaas-suse-virtualization/WSO2’s open-source DBaaS operator turns a Kubernetes object into a PostgreSQL VM on SUSE Virtualization, with TLS, credentials and monitoring wired up, in about 100 seconds. Here’s a quick install, including how to build its image without Packer.https://blog.5glinux.com/posts/netapp-trident-harvester-yamls/Tue, 13 Oct 2026 00:00:00 +0000https://blog.5glinux.com/posts/netapp-trident-harvester-yamls/A copy-paste version of my Harvester knowledge base article on NetApp Trident: every manifest and command for NFS, iSCSI and NVMe/TCP backends, with as little prose as possible.https://blog.5glinux.com/posts/longhorn-v2-spdk-rdma-vs-tcp/Mon, 12 Oct 2026 00:00:00 +0000https://blog.5glinux.com/posts/longhorn-v2-spdk-rdma-vs-tcp/Two snapshots of Longhorn’s SPDK-based v2 engine on the same three Ampere nodes: 1.12 with my RDMA patches, then 1.14 development builds with a newer SPDK. NVMe/TCP got about 7× lower write latency and now fills a 25 GbE link. RDMA still halves write latency.https://blog.5glinux.com/posts/kasm-vdi-suse-virtualization/Wed, 07 Oct 2026 00:00:00 +0000https://blog.5glinux.com/posts/kasm-vdi-suse-virtualization/Kasm Workspaces 1.19 has a built-in Harvester provider: it creates agent VMs on demand, streams desktops to the browser, and deletes the VMs when they sit idle. Here’s a working setup on SUSE Virtualization v1.9, including Windows desktops, and five upstream bugs to work around.https://blog.5glinux.com/about/Mon, 01 Jan 0001 00:00:00 +0000https://blog.5glinux.com/about/About Alejandro Bonilla
