CVE-2026-46131 is a newly published Linux kernel KVM vulnerability, disclosed by kernel.org and recorded by NVD on May 28, 2026, involving incorrect handling of nested Intel EPT and AMD NPT state during slow Hyper-V TLB flush hypercalls on x86 hosts. The bug is not a Windows flaw, but it lives...

CVE-2026-46076 is a newly published Linux kernel KVM vulnerability, disclosed by kernel.org and recorded by NVD on May 27, 2026, that fixes incorrect AMD nested-virtualization handling of VMMCALL instructions when a second-level guest runs under an L1 hypervisor. The bug is narrow, technical...

CVE-2026-46082 is a newly published Linux kernel KVM vulnerability, disclosed by kernel.org and listed by NVD on May 27, 2026, that fixes AMD SVM emulation so INVLPGA correctly raises an invalid-opcode exception when EFER.SVME is disabled. That is a mouthful, but the practical story is simpler...

CVE-2026-46014 is a Linux kernel KVM vulnerability published by NVD on May 27, 2026, covering broken save-and-restore handling for Last Branch Record model-specific registers in KVM’s AMD SVM virtualization path, with related Intel VMX bookkeeping also corrected. The bug is not the kind of flaw...

CVE-2026-46032 is a newly published Linux kernel KVM vulnerability, disclosed by NVD on May 27, 2026, affecting AMD nested virtualization code where a failed CR3 restore during nested VM exit could leave a guest running with corrupted virtual CPU state. The bug is narrow, deeply technical, and...

CVE-2026-46059 is a newly published Linux kernel KVM vulnerability, received by NVD on May 27, 2026, affecting AMD nested virtualization logic in nSVM when KVM restores an L2 guest after its first VMRUN. It is not yet scored by NVD, and the public record still sits in the frustrating “awaiting...

Linux 7.0’s merge brings a meaningful set of Hyper‑V improvements — most notably integrated scheduler support for MSHV — that together tighten the experience of running Linux as a Hyper‑V guest or even as a Hyper‑V root partition, and they open clearer paths for real‑time and nested...

Amazon Web Services has quietly flipped the switch on nested virtualization for a subset of its newest Intel-powered EC2 families, putting the long-awaited ability to run a hypervisor inside an EC2 virtual machine into general configuration for 8th‑generation Intel instance types — specifically...

AMD’s new push to enable “shift‑left” development for software‑defined vehicles (SDVs) — delivering a Virtualized Automotive Stack (VAS) that runs on AMD Radeon PRO V710 GPUs and AMD EPYC CPUs in Microsoft Azure and integrating Siemens’ PAVE360 digital‑twin environment — promises a meaningful...

AMD’s move to bring a Virtualized Automotive Stack (VAS) to Microsoft Azure — pairing Radeon PRO V710 GPUs and EPYC CPUs with Xen-based nested virtualization and Siemens’ PAVE360 digital‑twin environment — promises to accelerate “shift‑left” development for software‑defined vehicles, but it...

Proxmox can be run inside a Docker container — and yes, it actually works well enough to be useful for tinkering — but the method requires deliberate compromises, extra host privileges, and several manual workarounds that make it unsuitable for production and risky for anything beyond...

VirtualBox 7.1.12 sharpens Linux 6.16 support and Windows stability Subhead Oracle’s latest maintenance update, released on July 15, 2025, delivers kernel 6.16 readiness for Linux hosts and guests, steadier Windows behavior under Hyper‑V, and targeted fixes for networking, recording, and nested...

Virtual machines are nothing mystical—yet a small stack of persistent myths keeps turning otherwise sensible choices into needless fear, wasted money, or fragile setups that break at the worst moment. The five misconceptions below are the ones most likely to trip up hobbyists, home-labbers, and...

Microsoft’s plan to add Linux and Android subsystem support to Windows 365 Cloud PCs — long visible on the Microsoft 365 roadmap — resurfaced in headlines recently, but the full story is more nuanced than a single preview date. Microsoft documented nested virtualization for Cloud PCs (the...

Oracle’s VirtualBox 7.2.0 ushers in the most consequential update to the desktop hypervisor in several years, delivering first-class support for Windows 11/Arm virtual machines on Arm hosts, a redesigned user interface, expanded hardware feature passthrough, and a long list of stability and...

VirtualBox’s long march into the ARM era has reached a major milestone: version 7.2 delivers true ARM-on-ARM virtualization, a redesigned UI, macOS Metal-backed 3D experiments, and a broad set of stability and compatibility fixes that make this release the most consequential VirtualBox update of...

Pushing the boundaries of operating system flexibility has long been a point of pride for Windows enthusiasts. Over decades, Microsoft’s desktop platform has earned a reputation for not only powering modern hardware and productivity workloads but also for its backwards compatibility and...

When attempting to install Hyper-V within a Windows Server virtual machine, many IT professionals encounter persistent errors that can derail testing, nested virtualization strategies, or entire hybrid infrastructure plans. As more organizations adopt layered virtualization—running Hyper-V...

For seasoned Windows users, the allure of constructing a tailored development environment is irresistible—especially in an age where applications, libraries, and containers sprawl unchecked, threatening the stability and cleanliness of one's daily driver system. This desire for isolation and...

Few acts in the digital world rival the thrill of installing a brand-new operating system—except, perhaps, doing so in a way that lets you hit “Undo” if things go pear-shaped. That’s the magic of virtual machines. If you’ve ever wondered how to dive headfirst into Windows 11 without risking your...
