Foreshadow vulnerability on XenServer and XCP-ng

This is a recap on the latest Foreshadow vulnerability and how it affects XenServer and XCP-ng. Foreshadow, XSA-273 Yet another Intel x86 security issue… Basically, someone could steal data in RAM, outside the VM boundaries (ie: from other VMs on the same host). If you have non-trusted users in your

Killing Processes that Don’t Want to be Killed

This article originally appeared on lwn.net. Suppose you have a program running on your system that you don’t quite trust. Maybe it’s a program submitted by a student to an automated grading system. Or maybe it’s a QEMU device model running in a Xen control domain ("domain 0" or “dom0”), and you want to make sure […]

Xen Project Hypervisor Power Management: Suspend-to-RAM on Arm Architectures

This is the second part of the Xen Project Hypervisor series on power management. The first article focused on how virtualization and power management are coalescing into an energy-aware hypervisor. In this post, the focus is on a project that was started to lay the foundation for full-scale power management for applications involving the Xen […]

Xen Project Hypervisor: Virtualization and Power Management are Coalescing into an Energy-Aware Hypervisor

Power management in the Xen Project Hypervisor historically targets server applications to improve power consumption and heat management in data centers reducing electricity and cooling costs. In the embedded space, the Xen Project Hypervisor faces very different applications, architectures and power-related requirements, which focus on battery life, heat, and size. Although the same fundamental principles […]
