Hello, I have neutron with vxlan tenant networks. I'm using openvswitch to make vxlan tunnels. Today I found strange problem with instances with Windows server installed on guests. First problem is that tcp sessions (like RDP connection beetween two servers) in such tenant network are sometimes disconnected for a while (like packet loss in network). Second issue is that I have not good performance on windows. My hosts have got 10Gbps network cards, I have set jumbo frames (mtu=9000 on hosts) and if I set for example mtu=8950 on linux guests than I have about 9Gbps when test with iperf. On windows I have about 2-2.5Gbps with mtu=1500 and even less with bigger mtu. Do You maybe have such problems with windows guests using vxlan tunnels network? I'm testing it on Windows server 2012 R2.
