Surprisingly... #qemu 9.0.0 seems to compile just fine on #Slackware 15! Yay! 🤓

This being said, I am only on:

[2407/9553] Compiling C object libqemu-aarch64_be-linux-user.fa.p/linux-user_uname.c.o

So there is still plenty of time to mess things up. Let's see how it goes, and if the end result is usable.

And I am pleased to report that #qemu 9.0.0 compiles straight on #slackware 15 with almost no fiddling at all!

Took a while on my little server, but:

$ qemu-system-x86_64 --version

Ooooh yeah! 🤓

#QEMU 9.0.0 is out:

https://www.qemu.org/2024/04/23/qemu-9-0-0/

https://wiki.qemu.org/ChangeLog/9.0

"'block: virtio-blk now supports multiqueue where different queues of a single disk can be processed by different I/O threads

migration: support for “mapped-ram” capability allowing for more efficient VM snapshots, improved support for zero-page detection, and checkpoint-restart support for VFIO

ARM: architectural feature support for ECV, NV, and NV2

ARM: board support for […] raspi4b (Raspberry Pi 4 Model B)"'

Having the hardware to build Haiku inside Haiku makes a good match, this way I can see if updating libraries for #haikuports breaks a build or not, in this case updating #zstd to 1.5.6, no issues in building Haiku and booting it with #Qemu. #HaikuOS

I'm running #NetBSD (#ARM64 version) with #XFCE & #Mate on #QEMU (X11/xfce wouldn't run under #VMWare yesterday), and what I've seen is that ALL system prefs/admin tools from these DEs are not ported over to BSD. You only get the bare minimum of the DE. This shows how apart #Linux and #BSD have grown. Which means that if they care about the #desktop, they need to fork one of these DEs (maybe #LXDE or #LXQT would be best instead), and properly develop it for their own use case.

Is there a GUI for #qemu that people would recommend? Is everyone just cargo-culting qemu invocations?

#amd64 offers the best support and is fast.
#arm64 is very efficient and also very fast.
#riscv is amazing & exciting (but slow with my current hw, but I can deal with it)

While amd64 & ARM64 work perfectly fine with #FreeBSD, the #RISCV hardware support (beside #qemu stuff) is still very limited. Currently, #Ubuntu and #OpenBSD work very well there.

vDPA: support for block devices in #Linux and #QEMU – from @sgarzarella

https://stefano-garzarella.github.io/posts/2024-02-12-vdpa-blk/

"'"A vDPA device is a type of device that follows the virtio specification for its datapath but has a vendor-specific control path.

vDPA devices can be both physically located on the hardware or emulated by software.

[…]

Below are several examples on how to use VDUSE and the QEMU Storage Daemon with VMs (QEMU) or Containers (podman). These steps are easily adaptable […]

slirp4netns is this weird thing for unprivileged network namespaces:

https://github.com/rootless-containers/slirp4netns

It's required by #podman because it runs without root privs.

The #RISCV in #QEMU thing also works with classic #docker, but I'd rather use Podman for improved isolation.

TIL that you can just do this:

dnf install qemu-user-static-riscv slirp4netns podman

podman run --platform=linux/riscv64 -it docker.io/riscv64/ubuntu bash
