Sto eseguendo SuperMicro 6048R-E1CR36H Storageserver su Ubuntu Xenial 16.04.03 LTS e Xen
Kernel: 4.4.0-97-generico Xen: xen-hypervisor-4.6-amd64: amd64 / xenial-security 4.6.5-0ubuntu1.2
Problema: quando eseguo xl create o xl restore, visualizzo questo messaggio di errore:
libxl: notice: libxl_numa.c:499:libxl__get_numa_candidate: NUMA placement failed, performance might be affected
Su altri sistemi xen non ho notato lo stesso messaggio, come potrei risolvere questo errore?
Ecco le informazioni xl. Sto eseguendo 24 core su 2x chip Xeon E5-2620 v3. https://ark.intel.com/products/83352/Intel-Xeon-Processor-E5-2620-v3-15M-Cache-2_40-GHz
