CVE-2026-89775 lets an ARM64 KVM guest read and write host kernel memory at 64-bit granularity when nested virtualization is enabled.
LXC oder KVM auf Proxmox? Hier erkläre ich mit echten Benchmarks und CLI-Beispielen, wann du Container und wann VMs nutzen solltest.
We hit 95%+ bare-metal LLM speed using virtio-nvgpu on RTX 4090 for KVM guests. Get 115.2 tok/s on Llama 3 8B, slashing operational latency.

One system call, looped forever, is what running a virtual machine physically is. Here's what happens inside it — and why some VM exits cost far more than others.
Motivation The time has come: the big test. I got some simple binaries running on my...
Every device your guest sees is C code responding to memory addresses. Once you see the trick, QEMU stops being mysterious and its performance behaviour becomes predictable.
Build a production-like 3-node Kubernetes cluster on your local machine using Terraform, QEMU/KVM, and Cloud-Init. Fully automated from zero to kubectl get nodes in one command. Covers architecture, cloud-init automation, Calico CNI via Tigera Operator, the libvirt provider 0.8→0.9 rewrite, and every version upgrade nuance.
Three pieces, one running VM. Each exists because of a specific gap the layer below it leaves open — which is a better way to learn them than three definitions.
A quick, step-by-step guide to creating linked clones (copy-on-write disks) entirely within the Virt-Manager GUI, bypassing the command line and saving gigabytes of disk space.

KVM is a kernel module, but virtualization is a hardware feature. Understanding how those two relate is where most people's mental model of KVM breaks.
