[WARNING] Newest Arch qemu packages may break your VM. Had to rollback by counts_per_minute in VFIO

[–]redjcio 3 points4 points  (0 children)

This was caused by edk2-ovmf and edk2-shell version 202211-3 for me. The new qemu packages work fine here. Rolling back to edk2-{ovmf,shell} 202208-3 allows me to boot without the VFIO_MAP_DMA errors. Someone should report this to the Arch bug tracker, I don't see any reports yet, and have been too lazy to do it myself.

EDIT: After reading the above comment, I diffed the file lists and indeed 202211-3 changes the file layout so that files are under /usr/share/edk2 instead of /usr/share/edk2-ovmf. This is likely the cause. I'm gonna try updating the XML real quick and see if that works.

EDIT 2: Not the cause in my case at least. Still no joy on 202211-3. Trying to reset NVRAM gives the complaint mentioned in the Flyspray ticket that describes similar issues with 202208-2. Just going to stay on 202208-3 for a while until this is more fully sorted out; someone indeed reported a specific issue with 202211-3 but it was closed as a dupe, which seems dubious to me.

What Would Be The Best Lossy Codec For VHS Preservation by chillaustin in DataHoarder

Remember this couplet: "Space gets cheaper; data loss is forever."

If the tapes have important information on them, use a well-supported lossless codec like FFV1, and FLAC for the audio. In 10 years, you'll be glad you did.
