Re: Poor network performance
...s of course KVM and I’m using virtio model for VM’s NIC.
What we found is that on Xenial (where performance is poor) during test ovs-vswitchd process is using 100% CPU and there are some messages in ovs logs:
2017-05-12T14:22:04.351Z|00125|poll_loop|INFO|wakeup due to [POLLIN] on fd 149 (AF_PACKET(tap27903b5e-06)(protocol=0x3)<->) at ../lib/netdev-linux.c:1139 (86% CPU usage)
Identical setup (with same versions of ovs, libvirt, gemu and kernel) is working properly on Trusty.

Poor network performance

I have some problem with poor network performance on libvirt with qemu and openvswitch.
I’m using libvirt 1.3.1, qemu 2.5 and openvswitch 2.6.0 on Ubuntu 16.04 currently.
My connection diagram looks like below:
