#qemu — Public Fediverse posts

I got a little distracted today and decided to take one last stab at getting Windows NT Terminal Server Edition working in qemu, and I got it!

Turns out the answer to everything is SCSI. For whatever reason, TSE just will not work with IDE at all.

Using SCSI for Workstation and regular Server also make that installation faster and in a way, easier since you just have to install the driver during setup and then not think about it.

Updated the guide and driver disk to include drivers for the Symbios/LSI Logic SCSI controller

Now we're cooking with gas.

Just upgraded qemu from v10.2.4 to v11.0.3 on all my hypervisor nodes in my private cloud and it seems to went flawlessly.

Как мы сделали инкрементальную репликацию из OpenStack на уровне QEMU/KVM в релизе «Хайстекс Акура 4.6»

Если вы настраивали аварийное восстановление для OpenStack, то знаете частую проблему: при отказе от Ceph организация безагентной инкрементальной репликации требует поиска альтернативных способов отслеживания изменений. Самым очевидным кандидатом на эту роль выступает механизм QEMU Dirty Bitmaps — это хорошо изученный в экосистеме KVM/QEMU способ отслеживания измененных блоков (CBT). Однако его использование в OpenStack упиралось в отсутствие штатного API на уровне управляющего слоя. Из-за этого приходилось выбирать между двумя крайностями: строить инфраструктуру исключительно на Ceph или ставить агенты внутрь каждой гостевой ОС. Ниже расскажу, с какими ограничениями сталкивались наши пользователи раньше, как мы переписали логику работы с инкрементальными данными на уровне гипервизора и что еще полезного появилось в релизе

I dag har jeg brukt #gnomeboxes som kjører #qemu .

Installerte #Micro10 (Windows Lite-X) for #Garmin Express som nekter å kjøre på min #Fedora #linux

Liten installasjon (2 GB RAM, 20 GB disk), og en veldig liten og kjapp Windows 10 installasjon, med tilgang til USB og delte mapper.

Dette var så kjapt og enkelt at jeg kan slette min #Wine folder helt.

Nå får jeg endelig kjørt en oppdatering av kart og golfbaner for min klokke.

I hate to say it but the #grokpedia #qemu write-up: https://grokipedia.com/page/QEMU is better than the #wikipedia equivalent it was originally sourced from: https://en.wikipedia.org/wiki/QEMU

Of course it still has factual errors in it and it seems the all seeing #xAI has ceased doing edits since April. I guess they needed the compute for something else.

Q: How to create a VM in 10 seconds from the terminal?
A:

🦌 **kudu** — A TUI for creating and managing QEMU virtual machines on Linux

💯 A lightweight alternative to virt-manager and GNOME Boxes (without relying on libvirt)

🦀 Written in Rust & built with @ratatui_rs

Hmm I pulled a thread on #qemu's #virtio #crypto module and now I'm sorry I did 👀

Linux: Kernel 7.2.0 for X1000/e5500

Parallel to the release of Linux kernel 7.2.0, Christian 'xeno74' Zigotzky has finalized the compilation for AmigaOne X1000 and e5500 machines (X5000/20, X5000/40, Mirari, and QEMU VMs).

(It reminds me of a Hungarian tech news/forum site which wrote (they probably still do, I just don't go there anymore lol) about Windows all the time, and highlighted each Linux vulnerability saying "see, that's why you should just stick to Windows" while they also wrote about Windows vulnerabilities so they contradicted themselves pretty noticably. And the sad thing is they have quite a lot of readers who are also brainwashed zombies shilling Windows in the comment section, and if a Linux user accidentally finds the way there, he/she quickly gets humiliated like crazy. So Linux users are the elitists? Hmm, not so sure about that lol)

BAD NAUGHTY #OpenBSD!

where's the --harder option to #fsck when we need it?

(the root cause is that #QEMU crashed, but for OpenBSD's fsck to then leave /lost+found in a crash-causing inconsistent state is ... less than ideal)

I've only been back from holiday a day and I already feel like I'm burning out triaging the #qemu bug tracker. The flood of #llm assisted bug reports is not actually very helpful to the project even if they are real bugs. Just reporting more isn't going to help get the others fixed any faster.

Паравиртуализация при отладке графических приложений KasperskyOS в QEMU

Привет! Меня зовут Денис Молодяков, я — тимлид команды графики в KasperskyOS . Мы отвечаем за разработку графического стека полного цикла для микроядерной ОС: от создания низкоуровневых графических драйверов до всего необходимого для фреймворков. Современная реальность разработки диктует новые правила: удаленка и распределенные команды стали нормой. Моя команда не исключение — ребята базируются в разных регионах. При этом каждому разработчику требуется доступ к аппаратным платформам для сборки, запуска ОС, написания и отладки драйверов. Обеспечение каждого сотрудника полным набором плат сопряжено с серьезными логистическими и финансовыми затратами. В этой статье я хочу рассказать, как мы искали оптимальное решение этой проблемы и почему пришли к использованию методики паравиртуализации.

В заголовке моего ELF есть точка входа. Оказалось, её никто не читает

Три статьи я собирал файл и отдавал его эмулятору, ни разу в него не заглянув. Заглянул. Внутри два разных описания одних и тех же байтов, ответ на вопрос, откуда взялся адрес 0x80000000, и поле, которое я заполнял зря. Ну, открываем!

Моя рекурсия зависла навсегда, и это был правильный результат

Написал рекурсию тем же приёмом, что во второй статье, и программа повисла навсегда: возвращаться ей было некуда. Чиню, завожу стек и по дороге выясняю, что регистра sp в наборе команд нет вовсе. А потом урезаю стек до 128 байт, и сборка об этом не говорит ни слова. Ломать второй раз!
