Service-Hinweis: Wenn man in der Definition einer virtuellen Maschine bei qemu/libvirt den Prozessortyp auf „qemu64" stellt, lässt sich ein vorhandenes W10 auch dann auf W11 aktualisieren, wenn der real vorhandene Prozessor von Microsoft als nicht für W11 geeignet festgelegt wurde.
Mein i5-6500 wird für das Update abgelehnt, bei der „QEMU Virtual CPU version 2.5+" meldet die PC-Integritätsprüfung „Der Prozessor wird für Windows 11 unterstützt."

I see no point in doing this but...
ChromeOS Flex on #KVM with Single GPU Passthrough
Hmm, checked the options under the vm (FreeBSD), and I don't see any hardware checksum options or tso options, which is a little strange. Need to see if the virtio net spec has support for these options. It could be that qemu doesn't support them.
It does look like virtio does specify csum offload and TSO offload as well, so looks like it's just missing code then.
It does appear that bhyve may suffer similarly, except for the netmap backend.
Looks like the SLIRP library for qemu could use some major improvements. Was doing some transfers from a qemu vm, and seeing "slow" transfers of around 120MB/sec and knew it should be faster. Looked at the window size and I was only seeing 64k. Looked at the host negotiate, and see the wscale option, but still only 64k on the vm. Looked at the VM negotiate, and there is no wscale option. Only option was mss 1460.
Welcome to the new era of TUIs.
**tui-uefi** — Build TUIs for your bootloader.
Works with Rust's x86_64-unknown-uefi target & runs in QEMU in the demo.
Written in Rust & built with @ratatui_rs
На #Pocket386 по умолчанию (на момент выполнения boot-сектора) выключена адресная линия A20.
Я уже и забыл про такой "подвох": #qemu, например, по умолчанию стартует эмуляцию со включенной A20.
[Перевод] Собираем и запускаем минимальное ядро Linux
Однажды на работе техлид порекомендовал мне проштудировать книгу Understanding the Linux Kernel Бове и Чезати. В ней рассмотрена версия Linux 2.6, сильно не дотягивающая до более современной версии 6.0. Но в ней явно ещё много ценной информации. Книга толстая, поэтому на её изучение мне потребовалось немало времени. Занимаясь по ней, я решил настроить такую среду разработки, в которой я мог бы просматривать и изменять новейшую версию ядра Linux — чтобы было ещё интереснее. Есть и другие статьи, в которых рассказано, как собрать ядро Linux. Но в этой статье я немного иначе организую и подаю информацию.
Holy crap y'all, Quickemu is amazing! I got Windows 10, (English United States cause English International only allowed me to choose English UK for some reason), installed it with Narrator, downloaded and installed NVDA, and it barely feels like I'm running a VM at all. I kinda wonder if it'd work well at all on the BTSpeak. I could imagine it passing through Braille access on a future BTBraille.
Anyway, two commands I've figured out so far, Control + Alt + G gives control back to Linux, and Control + Alt + F puts the VM in fullscreen.
Pues nueva versión de #Proxmox: la 8.4. Basada en #Debian 12.10 "Bookworm" con el Linux kernel 6.8.12 y el kernel 6.14 opcionalmente, #QEMU 9.2.0, #LXC 6.0.0, #ZFS 2.2.7 con compatibilidad para kernel 6.14 y Ceph Squid 19.2.1. Para más cosicas interesantes que han añadido, se puede leer en: https://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_8.4
In the wee small hours i decided to give #GnomeBoxes another chance as a possible alternative. Chose to install via #flatpak, coz my Host is 
#ArchLinux #KDEPlasma & i did not wish to risk possible gnome vs plasma file conflicts.
It did a fine job of installing an #ArchLinux VM [which i completed using the latest #ArchInstall v3.0.3], so then in an act of gross stupidity i ridiculously chose to see if it could handle a win10 VM via a 3-yr old ISO i have lying around. As i abandoned windoze "for real" in 2014, i had forgotten the many hours of time-wasting bullshit involved, at the end of which instead of getting something decent, you just get... windoze, ugh.
Anyway, so far it seems that GnomeBoxes is going ok, which makes a nice change as all prior tests of older versions failed to work properly. Doubt though atm that it'll persuade me to give up on #qemu / #kvm / #libvirt / #VirtManager. GB has no facility to Suspend VMs, so they need to be fully shutdown, which is a drag. Also, the FP version does not support USB transfer, which is a bugger, & so far i've not made #SharedFolders work [but think i know why].
