Hello, I was trying with newest driver downloaded from http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/ and also on older version.
I did small test with two instances on one host. Then all traffic is going only via br-int bridge in ovs (no any vxlan tunnel) and problem was the same. But when I manually remove both tap interfeces from ovs and put it into linux bridge than I not have this issue. So imho there is some problem with openvswitch. I'm using 1.11 version of opensvitch but yesterday I build from sources version 2.3.0 and still is the same :/ I'm using kernel 3.13 on compute hosts. Really anyone have got such issue with vxlan tunnels and windows guests? --- Best regards Sławek Kapłoński sla...@kaplonski.pl Dnia wtorek, 14 października 2014 07:15:24 piszesz: > Which virtio drivers are you using in your Windows guest? > > P > > On Oct 10, 2014 3:56 PM, "Sławek Kapłoński" <sla...@kaplonski.pl> wrote: > > Hello, > > > > I have neutron with vxlan tenant networks.
