IS gave me a copy of the libvirt xml for the guest, and I used it to build a VM as similar as possible (minus some details about storage/NIC). However I was still unable to reproduce on a ThunderX2 host. I asked a contact over at Ampere Computing to see if this symptom was something they'd seen before, but it didn't ring any bells. We are using host-passthrough CPUs, so one difference would be underlying CPU. I noticed that the failing guest log shows KPTI as a cpu feature but my (working) one doesn't. I tried forcing KPTI on (kpti=1) on the guest to compensate, but that also did not trigger the failure. I couldn't really spot any other interesting differences in the log.
