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.

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].

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.

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 ?
Depends on your definition of 'significant' and on the workload. Certainly
enabling huge pages, NUMA setting and removal of some unneeded devices can
help some workloads.
DPDK for sure is a fantastic feature for networking environments.
A bit over-rated, for most workloads, if you ask me...
Currently requires a bit too much configuration (in my opinion), but
certainly there are workloads who critically need it.

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].
