Re: [ovs-discuss] vhost_net and virtio for OVS

2013-10-22 Thread Ramana Reddy
I tried vhost_net with OVS 1.7.1 long back. In Ubuntu, you have to manually install vhost-net driver in the host machine. After driver installation, have to modify the the corresponding xml file of VM. On Wed, Oct 23, 2013 at 3:15 AM, Morgan Yang wrote: > Hi All: > > ** ** > > I’m current

Hi All: I'm currently using KVM with OVS. My VNIC's are set to "virtio". I have read about how "vhost_net" from QEMU/KVM improves performance and reduces latency by moving the VNET interface down to the kernel level. https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/
