Hello,
It was found that the KVM PPC64 emulator for the sPAPR machine leaks the host
hardware identity to all running guests. The sPAPAR(hw/ppc/spapr.c) emulator
populates the device tree for the guest with two fields "host-serial" and
"host-model". The values for these fields are taken via hypervisor from the
host device tree data exposed in "/proc/device-tree/system-id" and
"/proc/device-tree/model" file respectively.
Upstream patch:
