  • Best virtualization solution with Ubuntu 22.04
    If you want an all around easy to use tool that can manager containers (create on the fly, delete when unnecessary, etc.) look into vagrant. There are also options like xen and virtualbox but they are not so lightweight. All of them are in ubuntu repositories. Source: about 1 year ago
  • Modular building blocks: The case of Amazon
    On the other hand, EC2 was built in isolation by a team of two, Chris Pinkham and Chris Brown, working remotely from South Africa. The idea behind building EC2 was to allow developers to build and run their application on Amazon’s servers, regardless of what type of application it was. The plan was to build EC2 on top of an open source tool called Xen which made it possible to run several applications on one... - Source: / about 1 year ago
  • Announcing Rust 1.68.0
    There was of course a generation where Xen was the way to make kernel-level containers, but those kernels still had to communicate with a form of ABI. I barely used Xen so I can't say how many of the same concerns apply, but in any case, userland containers won out over kernel containers in the end, and I'm glad for it. Source: about 1 year ago
  • XSAs released on 2022-11-01
    Qubes OS uses the Xen hypervisor as part of its architecture. When the Xen Project publicly discloses a vulnerability in the Xen hypervisor, they issue a notice called a Xen security advisory (XSA). Vulnerabilities in the Xen hypervisor sometimes have security implications for Qubes OS. When they do, we issue a notice called a Qubes security bulletin (QSB). (QSBs are also issued for non-Xen vulnerabilities.)... Source: over 1 year ago
  • A Dad Took Photos of His Naked Toddler for the Doctor. Google Flagged Him as a Criminal.
    It depends greatly on the implementation you use and the rest of the tooling you use. Using QEMU+KVM directly & raw is very different from using libvirt-backed (which abstracts over various other backends like Xen [virt-manager])( (which is a lot closer to the VirtualBox experience) to make the whole experience easier and simpler).

  • VDI - Desktop Streaming Technology (Open-Source)
    Have you looked at Vagrant or Xen Project ? Source: over 2 years ago
  • need recommendations for a daily driver
    Then I'd suggest that you should consider a different hypervisor. What you are proposing (i.e. a lightweight Host OS + Plus Hypervisor, with everything else being run in VMs), describes Xen ( to a T. Source: over 2 years ago
  • best/simplest/fastest bare metal ( with GUI!) linux vm host for running a windows installation.
    As others have said, Proxmox. I think that would be a good choice. Other options: Xen KVM. There are also expensive enterprise solutions from Oracle, VMWare, & Citrix. Source: over 2 years ago
  • What's going on with Xen?
    So the "Xen Project" ( is mainly focused on helping "technical cooperation between Xen devs", without doing a lot to communicate about Xen itself. That explains a lot regarding outdated doc or user wiki, lack of great on-boarding and news about it. All of this, despite a pretty rich activity from a LOT of different companies on very interesting projects (just check the wide topics and... Source: almost 3 years ago
  • Virtualization ... or what enables the cloud
    Paravirtualization approach modifies guest OSes to include optimizations and avoid problematic instructions (ex. Guest OS is able to see the real hardware resources). Basically, guest operating systems can detect their virtual state and actively cooperate with hypervisor to access hardware. This improves performance. The downside is that guest operating systems need substantial updates to run this way, and the way... - Source: / about 3 years ago

What are the Top Most Open Source Virtualization Software?
It is often treated as the default standard in Linux hypervisors. Xen is known to be an excellent open source for paravirtualization.
Best Server Virtualization Software
A free, open-source virtual machine monitor (VMM), Xen Project was initially designed by a team at Cambridge University. The team later created their own company centered around Xen Project, which was purchased by Citrix. Since then, Xen Project has partnered with The Linux Foundation as part of its work to drive collaborative tools.
8 Free & Best Open source bare metal hypervisors (Foss)
Xen is an open-source software platform or Linux hypervisor distro maintained by the global community of developers It supports virtualization for x86, x86_64, IA64, ARM, and other CPU architectures. The Xen hypervisor is an enterprise-class alternative to proprietary virtualization platforms and hypervisors for x86 and IA64 platforms. Besides the open-source, it also available in the commercial version from Citrix.
Best VirtualBox Alternatives & Competitors [Top 7 2019]
Xen is the best VirtualBox alternatives and super functional without altering the hard disk of your computer. Hence, emulate the most popular such as IA-32, IA-64, x86, x86-64 e PowerPC 970. Execute, the best systems without a lag. Experience the same quality on multiple platforms at the same level as your native operating system with Xen.
Introduction to Top Open Source Virtualization Tools
Xen is a hypervisor that started out as a Microsoft backed startup at the University of Cambridge and has now risen to become one of the best Linux hypervisors. The Xen Hypervisor is inserted between the server’s hardware and the operating system. This creates an abstraction layer that allows multiple guest operating systems to be concurrently executed on a single physical server. Xen is included with most popular...
