A stack-based buffer overflow in QEMU's e1000 emulated NIC — tracked as CVE-2025-12464 — creates a reliable host-side denial-of-service vector when a guest processes short frames in loopback mode, and operators running qemu/qemu-kvm in multi-tenant or untrusted-guest environments should treat...

A reachable assertion in QEMU’s USB handling (usb_ep_get in hw/net/core.c) can be triggered from an unprivileged guest and crash the host-side QEMU process, producing a host-level denial-of-service that administrators must treat as a high-availability risk and remediate immediately. Background /...

The virtual machine landscape in 2025 is more capable and more competitive than ever: major vendors have shifted licensing models, GPU virtualization has moved from niche to mainstream in server environments, and open‑source stacks such as KVM/Proxmox, QEMU, and Xen have narrowed the feature gap...

The Linux kernel received a targeted fix for a subtle but potentially dangerous race in the AF_VSOCK transport: during a blocking connect, if a signal or timeout arrived after the socket had already reached an established state, the code could disconnect or reset that already-established socket...

Chinese state-sponsored actors have been observed deploying a sophisticated backdoor called BRICKSTORM to maintain long-term, stealthy access across public‑sector and information technology environments — with confirmed targeting of VMware vSphere management infrastructure, Windows systems, and...

A coordinated government and industry response has confirmed that a sophisticated Go‑based backdoor called BRICKSTORM has been used in targeted espionage campaigns to establish long-term persistence on appliances and virtualization management systems, with operators exploiting appliance blind...

Organisations facing the end of Windows 10 support now have a clear, pragmatic option to protect operations and buy time for a controlled Windows 11 migration: virtualisation — used strategically — can deliver centrally managed Windows 11 desktops to legacy endpoints while IT teams sequence...

Organisations facing the end of Windows 10 support now have a clear, pragmatic option to protect operations and buy time for thoughtful hardware refreshes: virtualisation — used strategically — can deliver centrally managed Windows 11 experiences to legacy devices while teams plan and execute...

WinBoat is an ambitious, open‑source project that lets Linux users run real Windows applications by launching a KVM/QEMU Windows guest inside a container and compositing individual program windows into the native Linux desktop — a pragmatic middle ground between Wine/Proton compatibility layers...

Proxmox VE doesn’t feel like “another Linux distro” — it feels like a purpose-built control plane for self-hosting, homelabs, and small datacenters that removes a surprising amount of the friction that trips up hobbyists and sysadmins when they try to run many services on one machine. If you...

I finally bought a MacBook, but I’m still keeping Windows as my main platform—and that experience says far more about how we use computers today than it does about brand loyalty. What started as a curiosity trip into Apple’s tightly integrated hardware-software world quickly became a study in...

Imagine upgrading Windows 11 Home to Pro and finding the same elegant interface—but with a suite of hidden tools that fundamentally change what your PC can do for work, security, and virtualization. Background: why this matters right now Windows 11 ships in multiple editions, but the difference...

There are far fewer reasons to run a full Windows install on a Mac in 2025 than there were three decades ago, yet for a shrinking — still important — slice of users the question is as practical as it is technical. Mark Lyndersay’s column captures that evolution: from SoftWindows and Connectix...

Windows 11 includes a powerful, low-friction tool for vetting unknown programs: Windows Sandbox — a built‑in, disposable virtual environment that boots a clean copy of the same Windows build you run on your PC, isolates any activity from your host system, and discards everything the moment you...

Running Windows Vista on a Windows 11 PC is entirely doable today — but only as a carefully configured virtual machine (VM) or by using Windows’ compatibility layers for individual programs; installing Vista directly on modern hardware remains impractical and unsafe. Overview Windows Vista is...

If you run a home lab, enabling four specific BIOS options—CPU virtualization (VT‑x / AMD‑V), IOMMU (VT‑d / AMD‑Vi), SR‑IOV, and C‑States—will be among the most impactful firmware tweaks you can make to turn old desktops and laptops into reliable, efficient server nodes for virtualization, GPU...

The discovery that a sophisticated espionage group is running covert Linux virtual machines inside compromised Windows 10 hosts marks a notable escalation in adversary tradecraft: rather than installing traditional on‑host malware, the attackers enable Hyper‑V, import a minimal Alpine Linux VM...

A veteran tinkerer has taken Windows 7 and stripped it down to an almost absurd extreme — a bootable x86 image that reports an on-disk size of just 69.0 MB — a proof‑of‑concept that vividly demonstrates the technical boundary between what an operating system needs to boot and what it needs to be...

Enterprises and home labs alike face a deceptively simple-sounding decision: which hypervisor will reliably run the workloads you care about, at the scale you need, without breaking the bank or compromising security. This feature unpacks the practical tradeoffs—performance, availability...

A days‑long internet stunt has become a serious technical demonstration: a veteran Windows tinkerer known as Xeno released a bootable Windows 7 x86 image that measures just 69.0 MB on disk — a size so small it fits comfortably on a vintage floppy image several times over. The build boots to a...
