Please find the full cli args and two guest logs for DIMM
initalization attached. As you can see, the freshly populated DIMMs
are probably misplaced in SRAT ('already populated' messages), despite
the fact that the initialized ranges are looking correct at a glance.
When VM is migrated to the destination (with equal RAM device
configuration) which is simular to a VM with 16G RAM this misplacement
is causing the mentioned panic in the guest. This should be very
easily reproducible and the issue is very critical as well, I don`t
even understand why I missed this issue earlier.
