I went with:
+Furthermore, guests with virtual NUMA cannot be saved or migrated
+because the migration stream does not preserve node information.
I've applied all three patches in this series to staging and 4.6. The
conflict you mentioned elsewhere (patch #1) was just the presence of
xc_domain_soft_reset in staging but not staging-4.6. I resolved it, I
don't think I can have gotten it wrong, but do check ;-)
