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 --------------BDE85DB92A8FD76EF257B82B Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> </head> <body bgcolor="#FFFFFF" text="#000000"> <font face="arial, helvetica, sans-serif">Hello<br> <br> As some may have seen recently OVS DPDK has been introduced to oVirt (<a class="moz-txt-link-freetext" href="https://ovirt.org/blog/2017/09/ovs-dpdk/">https://ovirt.org/blog/2017/09/ovs-dpdk/</a>).
