[ovirt-users] OVS DPDK Performance

[FERNANDO FREDIANI]

Hello

As some may have seen recently OVS DPDK has been introduced to oVirt 
(https://ovirt.org/blog/2017/09/ovs-dpdk/). This is very interesting 
feature which can make a huge performance difference in terms of network 
performance.

Just wanted to ask if anyone has tested it in any environment and made 
any comparison, specially for packet forward (e.g: running Virtual 
Routers or Virtual Firewalls with virtio) or packet dropping as well.

One doubt I have and if someone could clarify is: Should I enable DPDK 
in the Host any traffic forwarded to any VMs will automatically benefit 
from this performance gain of DPDK or there additional steps that need 
to be put in place inside the VM when sharing a physical Network Interface ?

Thanks
Fernando
