Dear all, I am so sorry to send this question in dev mailing list. I sent this to users' mailing list, but no one response and that list is not so active. So, may I ask this question in this list? If it is not ok, I say sorry in advance.
----------------------------------------------------------------------------------------------------------------- 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. Ubuntu 14.04 64bit 3. Updated packages I build DPDK successfully, but when I build memnic in VM according to the doc. A lot of error message displays: -------------------------------------------------------------------------------------------------------------------- #... (So many lines of errors) ... ... ...

[-Werror] cc1: all warnings being treated as errors make: *** [librte_pmd_memnic_copy.so] Error 1 ------------------------------------------------------------------------------------------------------------------ Then, I tried DPDK 2.0 and 1.8. with both of these version, I still meet a lot of errors just like 2.2 So, I want to ask 1. How to solve the problems? 2. Can I install OVS with SR-IOV feature by other ways? Thanks! -- Regards, Royce Niu
