Hi.
Does the virtualization layer causes any significant impact in the VM
performance, even a high CPU VM that justify the use of this feature ?
DPDK for sure is a fantastic feature for networking environments.

Hello John,
This is very interesting news for HPC guys. Accordingly to the
blog post there's a new “CPU passthrough” function. Which is
interesting.
Do you guys are targeting which market? I’m looking forward for
virtual nodes on a HPC environment.
Any intensive workload, CPU and memory bound especially, would benefit
from the configuration.
In memory DBs (SAP Hana, Redis and friends) for example, MapReduce
(Hadoop), etc.
For some workloads, low latency networking is also important
(especially for nodes inter-communication) and we are looking at DPDK
for it. See[1].
