How to get a rawhide i686 VM?

[Dmitry Belyavskiy]

Dear colleagues,

What is the simplest way to get a rawhide i686 VM? I came across a
nasty architecture-specific bug, and the code investigation isn't of
much help. There is no obvious way to access a core dump via mock
(could you please ping me if it exists?) and the VM looks like a
reasonable choice.

Any advice would be appreciated!

or

mock -r fedora-rawhide-i386 --no-cleanup-after foo.src.rpm

mock -r fedora-rawhide-i386 shell

    cd /builddir/build

I think
that's no longer possible, as it's been many years since Fedora stopped shipping
i686 kernels.

I guess you could try creating a VM with some other distro, like Debian, and running a
Rawhide container in it?

A.FI.

Fedora discontinued i686 installation support quite a while ago
now. As such there is no rawhide i686 VM or cloud image or container
image available.

The only usage of i686 libraries in Fedora should be in a multilib
context on an x86_64 installation, and even then maintainers are
encouraged to drop i686 builds of leaf packages.

With regards,
Daniel

run an i686 userspace in a x86_64 is about the best option these days.

Is there a guideline on how to do it?

dnf instal blah.i686 I believe should work, TBH it's been a long time
since I've tried anything i686.

Miroslav Suchy's answer earlier is the best one:

```
mock -r fedora-rawhide-i386 --no-cleanup-after foo.src.rpm
mock -r fedora-rawhide-i386 install <whatever else you need to install>

mock -r fedora-rawhide-i386 shell

cd /builddir/build
```
