[pve-devel] The network performance future for VMs

[Cesar Peschiera]

Oh, ok.

In the past, i had problems with DRBD 8.4.5 when OVS is enabled, so i had 
that change my setup from OVS to the Linux stack, after of it, i had no more 
problems with DRBD.

About of the problem with OVS and DRBD, i did not test in depth the problem 
(in the season of preproduction phase), but if i not bad remember, maybe the 
problem appears when "OVS Intport" is enabled, or maybe only when OVS is 
enabled in the setup.

I was using PVE 3.3

So now my question is if DPDK can be activated also with the Linux stack?.

dpdk will be implemented in openvswitch through vhost-user,
I'm waiting for ovs 2.4 to look at this.

Objet: [pve-devel] The network performance future for VMs

Hi developers of PVE

I would like to talk about of the network speed for VMs:

I see in this link (Web official of Red Hat):
https://videos.cdn.redhat.com/summit2015/presentations/12752_red-hat-enterprise-virtualization-hypervisor-kvm-now-in-the-future.pdf

In the page 19 of this pdf, i see a interesting info:
Network Function Virtualization (NFV)
Throughput and Packets/sec "RHEL7.x + DPDK (Data Plane Development Kit)":

Millons packets per second:
KVM = 208
Docker = 215
Bare-metal = 218
HW maximum = 225

Between KVM and Bare-metal, the difference is little: 10

Also i see a list of HW NICs compatibility on this link:
http://dpdk.org/doc/nics

So, i would like to ask about of the future of PVE in network performance
terms.

Best regards
Cesar
