The hypervisor is KVM, the same kernel module under EC2, Google Cloud, Nutanix AHV and OpenShift Virtualisation. What Proxmox actually maintains, why the type 1 argument aims at the wrong line, and what the shared foundation does not buy you. NUMA Alignment on Proxmox VE — Why It Matters and How to Get It Right https://blogs.damiendye.uk/en/proxmox/numa-alignment-proxmox/ Fri, 07 Aug 2026 09:40:00 +0100 https://blogs.damiendye.uk/en/proxmox/numa-alignment-proxmox/ On multi-socket systems, a VM with its vCPUs on one NUMA node and its passed-through device on another loses 20–30% throughput before you've even looked at anything else. Always Use Q35, Not i440fx — Why It Matters on Proxmox VE https://blogs.damiendye.uk/en/proxmox/q35-not-i440fx/ Fri, 07 Aug 2026 08:45:00 +0100 https://blogs.damiendye.uk/en/proxmox/q35-not-i440fx/ The two QEMU virtual chipsets are not interchangeable. Q35 provides a proper PCIe topology that passthrough, modern Windows, and the wider KVM ecosystem all depend on.
