azure: [In preview] Public Preview: VM vCore customization features disabling simultaneous multi-threading (SMT/HT) and constrained cores

Azure Updates

2025-10-22

Azure announced a public preview of VM vCore customization that gives customers greater control over virtual CPU configuration. The preview introduces two capabilities: disabling simultaneous multithreading (SMT/Hyper‑Threading) on vCPUs, and constraining the number of cores exposed to the guest. These options help optimize single‑threaded workload performance, reduce license costs by limiting visible cores, and improve CPU isolation and predictable performance. The features are available in public preview and can be configured through Azure management interfaces.
