Well, there was an issue vith virtio at one time (interrupt handler did not have the right iopl for virtio callback). http://git.dpdk.org/dpdk/commit/lib/librte_eal/linuxapp/eal/eal.c?id=fd6949c55c9a48e81c625138679159829d51ac51 Now... time has passed since then. It is worth checking the issue is still here, and if it is the case, revisit this. I suppose virtio pmd should deal with this itself. -- David Marchand
