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.

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. Y.

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. Y.
Agreed

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!
