Alright, I will do what I did, if it comes up again. I will try to augment our tests to include an apt upgrade with -proposed. Thank you. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

Looking at Jason Wang's commits, it seems like it must work at least a little with qemu (because he committed it) but either 1) not *that* well or 2) someone else told him about trying to run firecracker or some other VMM that more closely assumes the specification in this area, since he modified

We can check it out, I have a question though, is there a way to get a pre-captured image with -proposed in it? We could integrate this into a CI system to do more monitoring. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in
