I did a quick Google search to make sure the question hadn't already been answered (apparently not). Now I'm reaching out to the real experts :) I=E2=80=99m currently exploring Proxmox for some use cases that require low-latency and deterministic behavior - particularly in the context of real-time workloads. I=E2=80=99m wondering if there are any current plan= s or ongoing discussions around: - Supporting a real-time kernel (e.g., with the PREEMPT-RT preemption model= ). - Enabling and integrating real-time system configurations, such as: - Integrated workflows for CPU isolation, IRQ affinity, and low-latency tun= ing - vCPU pinning, and using real-time scheduling policies (e.g., SCHED_FIFO, SCHED_RR) - Integration or support for tools like tuned to do the kernel configuration customization options relevant to RT - Integration with PTP... Are there any official efforts or community-led initiatives in this direction? And if not currently on the roadmap, would this be something of interest to the Proxmox team or the community? Thanks in advance, and looking forward to your thoughts!
