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

HI Jianfeng

Thanks for the ideas.  I’ve tried “--disable-hw-vlan”, with my “testpmd” binary, it is not recognizing this option…

With the debug options for VIRTIO, I’ve now gotten the following message.  I can’t figure out whether the “vlan filtering” is the fatal error.  Does anyone know?

Configuring Port 0 (socket 0)
PMD: virtio_dev_configure(): vlan filtering not available on this host
Fail to configure port 0

Using similar recipe, I can’t have testpmd pass the initialization.  Before I spend too much time, just wondering if I am working on mission impossible.  ;)  Your input is greatly appreciated.
