Comment 33 for bug 1797581

After triaging this again on a call with Andres (who originally reported this) this morning, we determined that this issue is no longer reproducible with MAAS. The only way for me to explain it at this point was that there was something wrong with the daily image MAAS was using last week, and a subsequent update fixed it. (It looks like the images were updated yesterday.)

Sorting my /var/lib/maas/boot-resources/cache directory by last-modified, I see the following:

@paelzer, if you'd like to test with any of those images, I've made copies. (Not sure where to put them, though - I wonder if your MAAS synced them as well?)

Still very weird that it worked in all cases we tested except when we allocated 2048 MB RAM.

I'd like to thank Ryan and Christian for their efforts on this "heisenbug". We should think about how to better handle issues like this, so that it's easier to peel back the layers and get to a point where everyone's environment can be consistent without this much effort. And we'll reopen this if it returns.
