AFAIU, it's > related to potential issues with the Xen version used on these systems? Thanks Stefan, Yes. My understanding is that the issue is because AWS is using older versions of Xen. They are in the process of updating their fleet to a newer version of Xen so the change introduced with Stefan's commit isn't an issue any longer. I think the changes are scheduled to be completed in the next 10-12 weeks. For now we are carrying a revert in the Fedora Kernel. You can follow this Fedora CoreOS issue if you'd like to know more about when the change lands in their backend. We work closely with one of their partner engineers and he keeps us updated. https://github.com/coreos/fedora-coreos-tracker/issues/1066 Dusty
