Re: [ovirt-users] New post on oVirt blog: Introducing High Performance Virtual Machines

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.

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.
