Hi, I am experiencing an irrecoverable system hang when trying to run the 'helloworld' dpdk example from within a CentOS 6.5 guest (4 VCPUS, 7GB RAM), running on VirtualBox (Windows host).
Specifically, I have successfully built dpdk-1.6.0r2 for the "x86_64-ivshmem-linuxapp-gcc" target. I perform the following initialization actions without problem (all as root): 1. mkdir -p /dev/hugepages 2. mount -t hugetlbfs nodev /dev/hugepages 3. echo 0 > /proc/sys/kernel/randomize_va_space 4. modprobe uio 5. insmod $RTE_SDK/$RTE_TARGET/kmod/igb_uio.ko Afterwards I launch the app as root as follows: $ ./helloworld -c f -n 4 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 1 on socket 0 EAL: Detected lcore 2 as core 2 on socket 0 EAL: Detected lcore 3 as core 3 on socket 0 EAL: Skip lcore 4 (not detected) EAL: Skip lcore 5 (not detected) EAL: Skip lcore 6 (not detected) EAL: Skip lcore 7 (not detected) EAL: Skip lcore 8 (not detected) ... EAL: Skip lcore 62 (not detected) EAL: Skip lcore 63 (not detected) EAL: Searching for IVSHMEM devices... EAL: No IVSHMEM configuration found! EAL: Setting up memory... The app freezes at this point, and after a while the guest OS freezes as well, forcing me to power it off from the host (Virtualbox). After a guest reboot I cannot find anything in the kernel logs related with the hang. Note also that the above steps have been validated, and the app has successfully run, on a native CentOS 6.5 machine. Any idea of what could be the cause for this behaviour? Thanks in advance, Nikos
