More mbuto pain
by David Gibson 05 Jul '22

05 Jul '22

Now that the mbuto profile change is around, I tried getting the passt tests working. I fixed a couple of minor problems, before hitting another mbuto issue. On my host, mbuto isn't managing to find and include the virtio_net module. I think this is because on current Fedora the modules in /lib/modules are compressed. So it needs to include: /lib/modules/5.18.6-200.fc36.x86_64/kernel/drivers/net/virtio_net.ko.xz but I think it's only looking for a plain '.ko' file. I had a look at the mbuto code to see if I could fix it, but I'm afraid mbuto is a long way past the complexity level at which I find shell remotely comprehensible. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.

[PATCH] test: Add external mbuto profile, drop udhcpc, and switch to it
by Stefano Brivio 02 Jul '22

02 Jul '22

This depends on a future change in mbuto to accept external profile files. Add a file defining what we need for tests and demos, dropping udhcpc, plus udhcpc and dhclient scripts as they're not needed anymore, and switch to it.
