After loading the uio and igb_uio module and setting up hugepages, I try to run the helloworld demo application. As soon as the helloworld displays the "hello from core 1, hello from core 0" messages, I loose all network connectivity to the VM. If I try to run the helloworld application remotely the output freezes after the following: # ./build/helloworld -c 3 -n 2 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 0 on socket 0 EAL: Detected lcore 2 as core 0 on socket 0 EAL: Detected lcore 3 as core 0 on socket 0 EAL: Support maximum 128 logical core(s) by configuration.

I haven't been able to try DPDK 1.8.0 because it doesn't compile on the latest Fedora Server 20.
