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: Reddit / 23 days ago
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: Reddit / 5 months ago
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])(https://virt-manager.org/) (which is a lot closer to the VirtualBox experience) to make the whole experience easier and simpler). - Source: Reddit / 7 months ago
Have you looked at Vagrant or Xen Project ? - Source: Reddit / about 1 year ago
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 (https://xenproject.org/) to a T. - Source: Reddit / about 1 year ago
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: Reddit / over 1 year ago
So the "Xen Project" (https://xenproject.org/) 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 That explains a lot regarding outdated doc or user wiki, lack of great on-boarding and news about it.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: Reddit / over 1 year ago
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: dev.to / almost 2 years ago
