libvirt VS cool-retro-term

Only in trivial cases. The problem is when another part of the program holds a function pointer (eg callback) into the library which has been unloaded.

libvirt has long been linked with -Wl,nodelete to avoid this:

So, next I setup cockpit and cockpit-machines, which works to create VMs (via cockpit-machines) but they use tcg/qemu i.e. emulation and no KVM based h/w acceleration - my test VMs were very slow! I figured out while qemu+KVM works on command line, it doesn't work and the culprit was libvirt! After discussing with the good folks on #asahi channel and with tobhe (Ubuntu-Asahi creator), I gathered enough evidence to conclude libvirtd doesn't know the "right" qemu commands to exec and logged my findings to the libvirt project https://gitlab.com/libvirt/libvirt/-/issues/365 (which can probably use some of the community noise, to expedite the fix).

Nvidia 510 introduced a regression you can see the relevant issues here and here

The work to split into multiple daemons started a few years ago.

There have been a few complaints online in the Arch and Gitlab forums regarding this issue. https://gitlab.com/libvirt/libvirt/-/issues/410

The issue stems from a change in libvirt. Libvirt is responsible for parsing all your VM's XML and turning it into a QEMU command. Somewhere between libvirt version 6.6 and version 6.9, there was a slight change in the way USB devices are passed to QEMU, and obviously libvirt followed suit. As a result, some USB passthrough configurations, such as the MacOS one in the thread, as well as the onboard bluetooth for windows suffered errors.

It's a bug, fix is upstream: https://gitlab.com/libvirt/libvirt/-/commit/04736179b283f55f62616a20a1ec95c665aab8ca

This is the best way to play short of hooking up your needle printer as a faux teletype terminal.

Very related: Cool-Retro-Term (CRT) - a terminal that makes it look retro ;)

You're covered: https://github.com/Swordfish90/cool-retro-term

Seems like a good spot to mention https://github.com/Swordfish90/cool-retro-term

Cool Retro Terminal is a nice accessory for when doing recording or screenshots - cause it looks cool. Can't use it as my daily driver tho.

And enough settings in there you can make it look like your favourite old one.

I'd guess most things you can get now are just regular command prompt style windows with a "retro" look (colour scheme). Oooh, you can change the text to green and maybe add a scan line effect. I am looking for a full experience like the Secret Geometry programs! The only similar-ish one I have found is Cool Retro Term, but that is for Linux and Mac only it seems :/

not directly related, but I've been thinking about getting an old CRT monitor, launch https://github.com/Swordfish90/cool-retro-term and start working

This puts me in mind of Cool Retro Term. Lots of built in schemes.

Usually packaged by your distro.

This together with cool-retro-term[1] is an absolute must on my machines for real hacker hours.

I've enjoyed using this. I don't run it for long but I do run it sometimes for the sake of nostalgia. When I do run it, I run it in full screen for the complete experience. However, to balance practicality with nostalgia, I run a tmux session with the cool-retro-term, so that once I get tired of it, I can quickly switch back to my regular terminal without losing my terminal session.

The effects are configurable. I disable the settings named Burin, Glow Line, and RGB Shift to get crisper and less distracting experience. The RGB Shift setting is disabled for most built-in profiles anyway but enabled for some profiles like Vintage and IBM Dos. The Vintage profile is quite amusing. Everything is cranked way up. The blurry text and the incessant flickering of the screen create an unsettling impression that the monitor might break down any moment.

By the way, if you didn't notice it the app is named cool-retro-term and it abbreviates to CRT. The app icon[1] is also a CRT followed by the cursor. Guess what else abbreviates to CRT? Yes, "cathode-ray tube" of the cathode-ray tube (CRT) computer monitors
