This warning implies that SRAT may be wrong. And I just noticed that this may not be vanilla 4.2:
[ 0.000000] DMI: Xen HVM domU, BIOS 4.2.amazon 01/24/2014
Are we on a custom HVM BIOS? That's where memory is described to domain.
Although NUMA issue may be somewhat orthogonal, it still may be worh looking at. Andrew, can you do this on booted guest:
acpidump > acpi.dat
acpixtract -a acpi.dat
iasl -d srat.dat
and post here srat.dsl
And again, seeing guest config file would be important.
