Arch Linux

Ping? Without this fix, libguestfs on Arch is completely and utterly broken. This is causing real drama for downstream users of Arch libguestfs. I've also seen increasing activity in the AUR trying to work around the issue.

Are any Arch users actually using libguestfs? It's a "must have" for me which means I build it myself. I'm surprised it's not more popular considering how useful it is for virtualization fans.

It has been possible to work around this by installing the lts kernel and providing the path to the lts kernel and its modules using the environmental variables SUPERMIN_KERNEL and SUPERMIN_MODULES

can you try supermin 5.3.1-1 from community-testing?

This is how we get around this (currently) but going to test latest

We were building against 5.12.14

Building it against linux-lts would work too as @ekrebs suggested

This is how we do it (downgrades kernel, just for references)

```
# 5.13+ problem resolved by building the qcow2 against 5.12 using libguestfs-1.44.1-6

sudo pacman -U "${LIBGUESTFS_PACKAGE_URL}"
rm -rf /var/tmp/.guestfs-*
libguestfs-test-tool

```

libguestfs-test-tool runs successfully with 5.3.1-1.

Thanks!

@Toolybird I am not actively using it but I can see its usefulness and would like to!

I just ran libguestfs-test-tool with "TEST FINISHED OK" on 5.10.79-1-lts. Am I understanding correctly that if I stick with LTS, I should be okay to use libguestfs?
