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. Fernando On 31/10/2017 05:56, Yaniv Kaul wrote:

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].

Hello! Just a quick heads up that there is a new post on the oVirt blog:
Introducing High Performance Virtual Machines <https://ovirt.org/blog/2017/10/introducing-high-performance-vms/>
In a nutshell:
oVirt 4.2.0 Alpha, released on September 28, features a new high performance virtual machine type. It brings VM performance closer to bare metal performance. Read the blog post. <https://ovirt.org/blog/2017/10/introducing-high-performance-vms/>
See you on the oVirt blog!
