format-udf VS Single-GPU-Passthrough

The note about the partition table makes me wonder how he was formatting the drive. https://github.com/JElchison/format-udf specifically does some partition table related hacks to make UDF maximally compatible with different platforms.

I recall getting UDF cross compatibility required a bit of non-trivial work[0], did this improve recently?

Or avoid NTFS all together. Use UDF https://github.com/JElchison/format-udf

> can't start shipping SD cards formatted with btrfs until Windows supports it out of the box

3rd parties can write drivers for Windows, you know. A small, read-only FAT partition on a USB stick or SD card could contain the installable drivers necessary to read/write the rest of the disk.

However, that's unnecessary. The best option for a universal file system is UDF. Windows, Mac, and Linux all have full read/write support.

See: https://github.com/JElchison/format-udf

It seems like exFAT has the best compatibility across systems, and for reasons I can't remember, I went with UDF (format-udf).

If wikipedia and 4-6-8 years old stackexchange info remains up to date apparently the disk needs to be UDF formatted in Linux with https://github.com/JElchison/format-udf to be gain true cross platform https://github.com/JElchison/format-udf to be read/write enabled across all platforms

Yes but that's a different kettle of fish. You then don't need two gpus, although if you do it can be useful. Start here and see how deep the rabbit hole goes https://github.com/joeknock90/Single-GPU-Passthrough

Im assuming you're on a single gpu setup and, as such are trying to do single gpu passthrough with a single nvidia card. so you'll likely have to run some libvirt hooks or smth to run scripts to unbind your gpu once you start your vm. In which case id suggest going through these two guides 1 2 which go over completely passing through your single gpu when you start your vm

Out of curiosity, who is Muta, the video dude, or the guide writer, or someone else? From the GitHub it sounded like running the commands from the guide would create a qemu.d/[VM Name]/prepare/begin/start.sh . If I were to simply create those directories myself, and then script as described in the video, I should be good?

Thanks for the info. Some of these I recognize from a single gpu passthrough project on github that i used on my main rig... https://github.com/joeknock90/Single-GPU-Passthrough
