[Openstack] Problem with neutron

Hello,
Now I got successfully booted instances with attached network. But
network still is not working. DHCP service doesn't assign fixed IP to
instance so I addet it manualy. I assign floating IP to that instance.
When I ping floating IP host is unreachable. With tcpdump in XenServer I
can see this:
15:04:30.683155 IP 10.10.50.230 > 10.10.50.231: GREv0, key=0x1, length
50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28
15:04:30.683303 IP 10.10.50.232 > 10.10.50.231: GREv0, key=0x1, length
50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28
15:04:31.683108 IP 10.10.50.230 > 10.10.50.231: GREv0, key=0x1, length
50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28
15:04:31.683243 IP 10.10.50.232 > 10.10.50.231: GREv0, key=0x1, length
50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28
10.10.50.230 is neutron host's guest networks IP
10.10.50.231 is XenServer guest network's IP
10.10.50.232 is other XenServer network IP, I don't know why it appears
there.
10.5.5.4 is instances fixed IP.
So as I can check network works like: internet -- neutron host --
XenServer -- instance
And it fails somewhere between XenServer and instance, I am not strong
with OVS, but I think problem is somewhere with OVS configuration.
"ovs-vsctl show" in XenServer: http://paste.openstack.org/show/57462/
Integration bridge is xapi4
I got two instances, both have integration networks attached and can
ping each other.
OVS plugin agent's configuration in nova-compute:
[ovs]
tenant_network_type = gre
tunnel_id_ranges = 1:1000
enable_tunneling = True
integration_bridge = xapi4 # Integration bridge in XenServer
tunnel_bridge = br-tun
local_ip = 10.10.50.231 # Guest network's IP in XenServer
Also I turned off firewall driver in ovs plugin agent's configuration:
firewall_driver = neutron.agent.firewall.NoopFirewallDriver
Thanks.
