[dpdk-dev] Running DPDK in a VM
Hi! I am looking at running DPDK in a VM, I would like to know if there are any limitations when doing this in terms of any DPDK features that do not work in a VM The only post I came across for running DPDK in a VM is this: http://dpdk.org/ml/archives/dev/2013-September/000441.html As an example, I tried to run the DPDK test suite (DTS, http://dpdk.org/doc/dts/gsg/ ) and see some tests fail saying virtio nics are not supported (Specifically, the ethertype_filter and five_tuple_filter tests give an error: FAILED ''virtio nic not support syn filter''). I would like to know if there are any limitations along these lines when running DPDK in VMs as compared to physical machines/NICS Thanks!

[dpdk-dev] EAL: No probed ethernet devices
Hi, I am running the DPDK test suite (DTS) in a VM and I see a lot of the test cases failing when running the testpmd application I manually run the testpmd application as follows and I see this error: test at pts00606-vm2:~/dpdk-16.04$ sudo ./ppc_64-power8-linuxapp-gcc/app/testpmd -c 1 -n 4 -- -i --max-pkt-len=9000 --port-topology=loop --txqflags=0 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 8 on socket 0 EAL: Detected lcore 2 as core 16 on socket 0 EAL: Detected lcore 3 as core 24 on socket 0 EAL: Support maximum 256 logical core(s) by configuration.

Any insights or pointers to this would really help Thanks a lot!
