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.

I would like to know if there are any limitations along these lines when running DPDK in VMs as compared to physical machines/NICS
