  10. What would be the equivalent of Scheduler KIST (a C-tor option at one time) in #Rust #Arti #tor? Certainly not an option in the future paradigm. A man pages for the Cargo modules at (crates.io)? We can see "low water" in Arti which is exactly the cure. But it appears that a priesthood of operators will be in control of the fine tuning the torrc once had.

  15. as far as I understand

    #Xen: What is the minimal hardware we need to emulate to get a VM? We might need to customise/change the operating system.

    qemu(+kvm): Let's emulate the full PC with mainboard and all chipsets and everything. Damn that is slow. Lets reinvent optimised virtual hardware in the #VirtIO project.

  19. CW: На днях появился BlueHammer — опубликованный прототип уязвимости нулевого дня в Windows-системах. Позволяет повысить права (привелегии) в системе до уровня учётной записи SYSTEM или расширенных админских.
    Уязвимость нулевого дня оказалась опубликована вместе с протипом (примером) использования. Опубликовано человеком (Chaotic Eclipse), которому не удалось сообщить о проблеме через официальные каналы Microsoft, потому что соответствующее подразделение (MSRC) захотело прямо аж видео с подтверждением работоспособности данной уязвимости. Отказываясь иначе вести диалог и принимать информацию к сведению.

    Это тот апофеоз тотальной идиотии, который преобладает в Microsoft последние 10+ лет. Ниже расписано более детально по этой теме.
    Очередное дно пробито, но это не первый раз, а стабильность — это верный признак мастерства.
    Нет такого, что Linux или BSD-системы вдруг стали модными и популярными, это людям приходится уходить с Windows-систем из-за такого качества работы Microsoft.

  20. Xen Hypervisor – Open-Source-Virtualisierung für Systemadministratoren

    Hier kommt die Einleitung in das Thema mit Hinweisen, wozu du Xen als Systemadministrator wissen solltest. Xen ist ein leistungsstarker, open-source Type-1-Hypervisor, der dir ermöglicht, mehrere virtuelle Maschinen (Domains) parallel auf einem physischen Host zu betreiben, ohne dass ein Host-Betriebssystem dazwischen funktioniert. Du solltest Xen kennen, weil es in älteren Linux-Umgebungen wie Red Hat Enterprise Linux 5 eine Standardlösung für Virtualisierung war und dir hilft, […]

  21. At @bawuenet we're in the process of upgrading our #Xen #xcpng hypervisors to #uefi boot. Of course, we automate things and want to be able to reinstall our hypervisors from network boot. Our EFI netboot system is based on #ipxe which means it can only load EFI binaries. But xcp-ng ships the Xen kernel as a multiboot2 based image.
    As probably one of the most weird ways to solve this problem, I've decided to chainload #grub2 from iPXE and learned a bit! 🧵

  26. I wish this post by the Xen Project existed years ago when I was trying to understand the differences between Xen and KVM. Would have been a great jumping point to dig deeper.

  27. So back on #QubesOS / #Xen. There is definitely something wrong with how it forwards the A380 into the #windows VM.

    Now that I've remote desktop enabled (and can conenct with the A380 disconnected just fine) I now can also see a black screen via RDP when the A380 is passed into it.

    (Note: passing the two end devices, aka the one for the video and the one for the audio of the A380 worked just fine in KVM on #NixOS. So it is something Xen/QubesOS does that breaks it...
