They can exit qemu via an ACPI shutdown. I don't see the difference.
An ACPI shutdown is triggered by an authenticated user inside of the
guest.
The present exit is triggered by any other anonymous user on the
network, with the ability to send a lot of packets very quickly to the
VM guest. The guest isn't able to handle this properly (and rightly
that guest's kernel should be fixed). But I do see a difference.
Well the problem is triggered by the guest kernel writing garbage to
virtio-net's backend. That's why we're suggesting it's really a guest
kernel issue.
If the guest kernel writes something bad to qemu, we're may kill the
guest. That's not a qemu bug, it's the designed behavior.
