Hi Gurus,
I launched a virtual box based linux on my windows, and my PC is thinkpad T480.
After configured the huge pages as number of 2MBs and the cpu number as 4 on the vm linux, I build DPDK and run the example of hellowworld but get the below output, in which I saw the "invalid NUMA socket". What does it mean and does it matter, as I see the hello from core # is also printed.
[~ build]$ sudo ./helloworld
EAL: Detected 4 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Probing VFIO support...
EAL: PCI device 0000:00:03.0 on NUMA socket -1
EAL: Invalid NUMA socket, default to 0
EAL: probe driver: 8086:100e net_e1000_em
hello from core 1
hello from core 2
hello from core 3
hello from core 0
