Rancher Desktop no longer works on openSUSE Tumbleweed

[jandubois]

It is broken by an update to qemu-ovmf-x86_64 (see https://bugzilla.suse.com/show_bug.cgi?id=1230291).

Workarounds:

• Install an older version of qemu-ovmf-x86_64 if you can still find one
• Use the AppImage release of Rancher Desktop which comes bundled with its own copy of QEMU
• Wait for the qemu-ovmf-x86_64 package to be fixed by openSUSE

There is no action item in this bug for the Rancher Desktop team; it has to be fixed upstream. This issue is purely about tracking the problem.

It looks like using /usr/share/qemu/ovmf-x86_64-4m.bin instead of /usr/share/qemu/ovmf-x86_64-4m-code.bin works (drop the -code part). Reading the readme, I think this is because the -code firmware doesn't include efivars and needs to be paired with -drive if=pflash,format=raw,unit=1,file=ovmf-x86_64-vars.bin (where it points at a file that can be modified)? I'm very unclear about this point, and it might be good to ask people who know about this stuff. But it seems like adding that (pointing to /usr/share/qemu/ovmf-x86_64-4m-vars.bin) allows the system to boot.

I think we can set the firmware if needed to use that? Not sure if it makes more sense to use the single file, or get lima to also use -vars…
