We do run DPDK in VM, and we have not come across any major limitations. There are multiple ways to run DPDK in virtual machine, if you are using virtio devices: 1. vhost-switch : please refer following link: http://dpdk.readthedocs.io/en/v16.04/sample_app_ug/vhost.html 2. you can use OVS also as backend instead of vhost-switch. we've used both methods on our platforms and they work fine. > 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'').
