[dpdk-dev] Creation of mbuf pool for socket 0 failed on VM

[Murali Krishna]

Hi,



I have attached two 10G NICs to VM as pass-through devices and I’m trying
to run testpmd on the VM. I have assigned 4GB RAM and 2 cores to the VM.



/DPDK22/testpmd -c 0x3 -n 2 -d /DPDK22/librte_pmd_oce.so -w $P0 -w $P1 --
-i --nb-cores=1 --nb-ports=2



Where P0 and P1 are the PCI IDs of the two NIC ports.



Below is the complete testpmd app output:

Hugepage allocation:



mkdir -p /mnt/huge

mount -t hugetlbfs nodev /mnt/huge

echo 64 >
/sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages



Can someone tell me if there is anything wrong here.



Thanks,
