Dear Matthew, I think my DPDK works. However, I believe SR-IOV is faster than VirtIO in VM, so I want to have a try.
Is there any other solution to achieve SR-IOV with DPDK. I am amazing that MEMNIC is stuck at 2014. Nobody needs that with DPDK in VM? ------------------------------------------------------ ./tools/dpdk_nic_bind.py --status Network devices using DPDK-compatible driver ============================================ 0000:00:02.0 'Virtio network device' drv=uio_pci_generic unused=vfio-pci Network devices using kernel driver =================================== <none> Other network devices ===================== <none> ------------------------------------------------------- On Wed, Jan 20, 2016 at 2:49 PM, Matthew Hall <mhall at mhcomputing.net> wrote: > On 1/19/16 10:03 PM, Royce Niu wrote: > >> Hi >> >> I want to install an OVS/memnic software in a KVM virtual machine. >> >> For the higher speed, I install memnic/pmd (SR-IOV) instead of virtio, >> since I believe SR-IOV is faster than virtio. >> >> But, I meet some trouble when I build the memnic following the doc ( >> http://dpdk.org/doc/memnic-pmd) >> >> I download the most updated software DPDK 2.2.0 and memnic 1.3. >> >> My system is : >> 1. 2 VCPU 2G Mem >> 2.
