[dpdk-users] Cannot run Quick Start on ubuntu16.04.1 VM

[Marco Kwok]

Hello all,

I am running vmware workstation for ubuntu 16.04.1.
Following the guide here:
http://dpdk.org/doc/quick-start

everything is fine until this line:

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

I got permission denied even with sudo, so I get through it with:

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


Then I want to start the program testpmd and I found the argument of this
line is not supported:

> -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048


With this command to start the testpmd(my card is not eth0 and eth1 but
ens33 and 38 instead):
sudo build/app/testpmd -c7 -n3 --vdev=eth_pcap0,iface=ens33
--vdev=eth_pcap1,iface=ens38

Does anybody know how I could get through this?
