Anyone managed to run Intel DPDK-based application in a virtual machine?

I have an application based on DPDK which I'm trying to bring up inside VirtualBox.

Intel mentions paravirtualized network interfaces in its documentation but I could not find any specific instructions related to virtual machine compatibility.

The application fails with the following error:

EAL: coremask set to 3
EAL: 0 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size
PANIC in rte_eal_init():
Cannot get hugepage information

The drivers suitable for virtualization are:

  • e1000
  • igbvf
  • ixgbevf
  • virtio-net
  • vmxnet3

In VirtualBox, you should first try with a basic e1000 device.

About your problem "no mounted hugetlbfs", you must do this:

mkdir -p /mnt/huge
mount -t hugetlbfs nodev /mnt/huge
echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

You should refer to the quick start guide.
