Odd: if I send a TCP "MSS=600"-option to a Linux virtual machine, the option is ignored (by the system (with apache)) unless I disable tcp offloading!

It looks like my #aiagents file finally got into #qemu. Hopefully it will have some effect: https://gitlab.com/qemu-project/qemu/-/commit/3ab8a15569afa9ffd89971dff34d0636d48cae3c

I will attend the ESA Industry Space Days next week. I would be happy to meet and discuss our #RTEMS, #Linux, #NuttX, communication, #canbus, #SpaceWire, IP cores related work. Some examples
- for RTEMS CAN/CAN FD, there is near to merge Ti AM335x suport, result of this year Ning Zhang #GSoC
- motion control at #PiKRON (used by ESA for #satellite tracking and for LISA ground experiment), and at #CVUT (SaMoCon)
- for rapid prototyping CTU Simulink™ support for Linux and NuttX which can be easily extended for RTEMS and open-source pysimCoder which already target Linux, NuttX and RTEMS (ongoing preparation for Ahmad Hisham’ s thesis)
- the CTU CAN FD IP core is already available on mass produced MCU COTS silicon in addition to multiple FPGA applications including space ones
- RTEMS LwIP port started as our experiment during Premysl Houdek’s thesis and #GSoC is getting traction and was used at docking computer during Artems II mission (by the way, there will be presentation about the mission at #cvutfel by Milan Halousek at Sptember 24) and is used on TMS570 and ESP32C3 RTEMS ports
- our SumInt ADC conversion principle used in our HPLC instruments and tested at #nanoXplore for ESA which can have interesting potential for space silicon
- our NuttX support for IEEE 802.3cg 10BASE−T1S Open Alliance SPI MACPHY can be ported to RTEMS etc.
- I offer support for CAN/CAN FD emulation on #QEMU, #FlexCAN added this year
- lot of our other real-time work for Linux, NuttX and RTEMS, se my university Open Technologies Research Education and Exchange Services topics and theses lists
- we invest lot into #RISCV education at CTU, see our https://comparch.edu.cvut.cz/ pages with #QtRvSim emulator and our HDL education and sometimes even practically used cores and experiments
I arrive to Noordwijk around the lunch time on Tuesday September 15 and stay there to about 2 PM on Friday so there is lot of options to meet.

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

Pour la première fois, l'installateur de #ShichimiOS, une distribution #linux que je code, a fonctionné ! (j'ai installé l'os dans un qcow2)

Some people asked about performance, so here is a video of #RISC_OS #Merlin booting (instantly) and running a graphics demo in #QEMU, Merlin is using its own software framebuffer in this demo, not yet GPU acceleration:

* [ALERT] Lxqt gui conflicts with Security-Misc!
(disable if upgrading and keep disabled if updating Trixie)
* Have you allocated enough disk space?
Size of Trixie upgrade appears to overwhelm resources.
recommend targeted updates:
apt install –only-upgrade <package>
* comment out non-free in Kicksecure repo
* consider disabling repo until “dummy” dependencies and other issues are cleared up#Debian #tech #Privacy #Security #ConfidentialComputing #tor #Linux #Qemu #grub #virtualization

Back In The Day - early/mid 90s - I saw #SCO (or possibly #Novell) demo a version of #Unixware on some funky PC hardware where you could add and remove physical CPUs and memory on the fly. Does anyone remember what that hardware was?
And does anyone know when this feature will be added to #QEMU? It's just that my #FreeBSD testing VM has just started swapping, and I'd like to allocate more memory without having to stop it.
