Ouyang, Fixing this has revealed some problems to be fixed (for 2.0.0 at least for the first): - changing link status from qemu monitor triggers this error message (even if link status seems to be correctly set) testpmd> EAL: Error reading interrupts status for fd 0 - log macros in virtio pmd (especially for init) are still under a build option. They should be aligned on other pmds to make it easier to debug, see ixgbe pmd and/or thread: http://dpdk.org/ml/archives/dev/2014-September/005450.html Can you look at these ?
