Title:
[scalingstack bos01] bionic (arm64) instances always fail to boot on
eMAGs in this cloud
Status in linux package in Ubuntu:
Triaged
Status in qemu package in Ubuntu:
Invalid
Bug description:
This is something to do with the configuration or software versions
running here, since we have identical hardware running in an adjacent
cloud region but with different versions of the cloud/virt stack.
When we boot bionic arm64 Ubuntu cloud images in "bos01" and they land
on the eMAG systems, they always fail like this:

We tried to get IS to roll things back to match the working bos02, but
they said it's too different and not possible.
The working cloud is running Mitaka from the cloud archive on Xenial (qemu
2.5)
The broken cloud is running Queens from the cloud archive on Xenial (qemu
2.11)
The other thing someone suggested we try is that MDS mitigation is
enabled in the broken cloud, so we could disable it. No idea if that
makes sense tbh.
That's about all we have right now.
