Re: [dpdk-users] Running DPDK on Google Cloud Compute Engine (GCE)

[Rex Shang <rshang@gmail.com>]

I used the tool “DPDK_DIR/usertools/dpdk-setup.sh" to do all of the initialization.  It is quite intuitive to use as the steps are laid out.

Before binding, you need to bring down the link.  Looks to me your network device is “up”.  You should “sudo ip link set DEVICE down” before you bind.
