Hello,
I was having serious network issues using GRE and I have been
tracking it for a few weeks. Finally, I solved the issue but it
needs a proper fix. To summarize, I need a way to set MTU settings
of br-int and br-tun interfaces, enable MQ support in libvirt, and
run ethtool -L eth0 combined N command in VMs.
The detailed bug report and the explanation for the issue is here:
https://bugs.launchpad.net/neutron/+bug/1419069
There is a blueprint [0] on MQ support but it wasn't accepted.
What can we do about this performance problem and a possible fix?
Most people complain about GRE/VXLAN performance and the solution
appears to be working. I created a bug report and let the list know
to work on a better, flexible, and working solution. Please ignore
the ugly patches as they are just proof of concept.
Regards, Eren

I guess the MTU part should be fixed in Kilo as part of:
