Yes .. precisely! I'll reply to both email here, so I'm mixing replies to Diego and Kyle throughout. We had a similar discussion in #meta-virt about a month ago, when some AGL builds were running into a similar issue. The layout of the includes and requirement for the fragment were intentional, as was the broad nature of the bbappend matching. Without those fragments, I end up debugging end users' subtle runtime errors for any number of packages in meta-virt, so having issues pop up when the fragments can't be found, while annoying, is a useful flag for potential issues. I resisted making a copy of virtio.cfg available in meta-virt for exactly the reason Diego is bringing up. Maintaining them in two places is not ideal, and having them centralized is the goal. To solve the short term issue as we were talking about in #meta-virt, I did a couple of things: A "hack": https://git.yoctoproject.org/cgit/cgit.cgi/meta-virtualization/commit/?h=master-wip&id=40cae93f631e77286de7fa79101abee2f6c04618 But if you use that, you'll need to ensure via other means that you get the right configuration enabled. And something that I had wanted to do for a while, which is the actual solution I'm heading towards. https://git.yoctoproject.org/cgit/cgit.cgi/meta-virtualization/log/?h=master-test see commits: https://git.yoctoproject.org/cgit/cgit.cgi/meta-virtualization/commit/?h=master-test&id=44db8ee6ddf7c9eb1b5ffb22e9b83b3840997da9 and https://git.yoctoproject.org/cgit/cgit.cgi/meta-virtualization/commit/?h=master-test&id=8db75f2809318cfb4dbe1c6873c5a6bcfefc4d8c I still haven't done extensive testing with a lot of different kernels, hence why I haven't moved them to master yet. But with those two commits, I can remove all of the fragments in the layer and rely on the one true reference in the kernel-cache.
