Friends don't let friends expose #usb devices to their #qemu guests, especially when #virtio is right there. The usb sub-system is one of our older ones and is currently Orphaned will all the security implications that entails. We don't need more #llm driven vulnerability scanning - we need maintainers who know the problem domain taking the reigns.

Keeping the #qemu issue tracker under control involves regularly triaging the reports and labelling them so they can (hopefully) be routed to a developer who can look deeper. We have had an up-tick in submissions recently so I've experimented with an #agentskill to off-load some of the more routine things I do. Seems to work pretty well: https://lore.kernel.org/qemu-devel/202[email protected]/T/#u

I have code for 1 KiB PageGrain on MIPS qemu, which should enable a demonstration of handling a case very near VAX 512 B pages while seamlessly guaranteeing within-allocation-unit promotions to 4 KiB and 16 KiB for 64 KiB allocation units and also seamlessly handling superpage promotions to sizes that are power-of-four multiples of 64 KiB. I think there may have been some testing of a similar scenario using 256 KiB allocation units on LoongArch, but while it was verified that it didn't crash, not much was done to make sure that effective use was being made of sub- allocation unit -sized superpages esp. when there were multiple superpage sizes available between the minimum MMU mapping granularity and the kernel allocation unit.

Rolling pgcl forward to 7.0 and the intermediate pre-7.1 somehow resuscitated binutils issues with running LTP and DAMON on hppa and some others, but it got to having no LTP regressions vs. master on 16 arches. I still need to induce enough fragmentation within a qemu session to be able to observe non-negligible defragmentation costs that might be reduced.

QEMU frontend for running AmigaOS 4/MorphOS/AROS: Kyvos 2.0.0

George @walkero Sokianos' QEMU frontend Kyvos, designed to significantly simplify the setup and launch of AmigaOS 4, MorphOS, and AROS under QEMU, is now available in version 2.0.0, which aims to further improve the user experience and, for example, automates the entire installation process for AmigaOS 4.1 FE, including updates.

PSA for anyone using #QEMU #KVM for #SingleGPUPassthrough
Guides are all over the net suggesting hooks scripts invoking pci devices, unloading/loading kernel modules, and other unnecessary things. Here's my current hook script for starting the VM:

systemctl stop display-manager

That's it. And the reverse for teardown:

systemctl start display-manager

#IOMMU groups still apply, and you need to pass the correct PCI devices to your VM, but everything else is handled automatically.

Disclaimer that this is how it works currently for my AMD card. I did have a working setup with my NVIDIA card that did unload/load kernel modules, however it seems things have come a long way since I set that up.

Emulation: New, QEMU-specific graphics card driver for AmigaOS 4

QEMU developer Zoltan Balaton has released ATIRadeon.chip, a replacement for the graphics card driver included with AmigaOS 4. His driver is limited to the functions of the still relatively rudimentary ATI emulation in QEMU and therefore works flawlessly under this emulation—however, it is not compatible with real hardware.

#QEMU 11.0 is out! And with it an exciting feature I was working on: Support for #nitroenclaves. Yes, you can now launch your enclave via -kernel directly in QEMU 😁

https://wiki.qemu.org/ChangeLog/11.0

💻 The developers of #QEMU debuted on Tuesday version 11.0 of its machine emulator and virtualization software. It brings a lot of work on Arm and RISC-V host support while also dropping support for aging devices.

The first #qemu release of the year has been tagged: https://gitlab.com/qemu-project/qemu/-/commits/v11.0.0?ref_type=tags the big #TCG feature is the new discontinuity #plugin APIs. #32bit host support is finally dropped 🙂 As usual see the #changelog for the details: https://wiki.qemu.org/ChangeLog/11.0

Tried the original BashCore today, booting the RT kernel inside QEMU.
Used this command:

qemu-system-x86_64 \
-m 16G \
-cpu host \
-smp 8 \
-enable-kvm \
-drive file=BashCore2602-Maruta.iso,media=cdrom,readonly=on \
-net nic,model=virtio-net-pci \
-net user \
-vga virtio \
-display gtk,gl=on

It boots and idles at <250 MB RAM. Impressive.

Ich habe gerade eine Woche damit verbracht, einen Bug in meinem Kernel zu jagen, nur um festzustellen, dass es ein Fehler in QEMU TCG ist, der dafür sorgt, dass manche CPUs keine Timer-Interrupts mehr bekommen.

OoO QEMU/KVM with libvirt can do virtiofs-9p fileshares using hvf.
Even virtual TPM with swtpm works.

Only annoyance so far, I've yet to get Spice with virt-manager to work. With Spice-gtk it probably should be possible but none of the virt-manager packages has it built in.

The brew one works, the #Nix virt-manager package for whatever reason is even buggier than the brew one. It doesn't save the config. Even after enabling dbus manually.

Drivers switch went about as well as I could have expected: failed to boot to GUI, then I banged my head against the wall for a while before finding a lingering xorg.conf I swore I'd deleted, then everything just worked!

Asking the same question here as well.

When using libvirtd/qemu+kvm what is your preferred way for sharing a folder with a huge dataset >50TB into multiple guests especially in the case where you want the VM to be network isolated.

Are you using:
* the filesystem-"device": virtiofs, virtio-9p, mtp
* the disk-device: with dir-source
* link-local network with: NFS, SMB, ...
* a different architecture entirely?

Decided to switch from VMware Workstation 17 to QEMU + Virtual Machine Manager today and spent two hours debugging networking. Turned out the VM couldn't reach the internet and my host couldn't ping the VM due to two conflicting routes for the same subnet. Removed the old VM network route and everything started working - finally 🥳 .
