Subject VxLAN issue
Date Fri, 24 Oct 2014 13:53:32 GMT
Hi guys,

trying vxlan as isolation method, and although manual testing of vxlan
works fine (so kernel and IP binary are fine) - I'm dont have inter-host
communication at all...

Per documentation, I should have created a bridge (cloudbr3 in my example,
IP address is set on the bridge). trafic label set to  "cloudbr3" when
deployed zone

Here is brctl show output (removed unneeded lines)

[root@compute2 ~]# brctl showc
bridge name     bridge id               STP enabled     interfaces
brvx-5064               8000.ae4843b4b918       no              vnet0
cloudbr3                8000.089e01d9422b       no              eth3

[root@compute2 ~]# ip -d link show vxlan5064
10: vxlan5064: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue
master brvx-5064 state UNKNOWN
    link/ether ae:48:43:b4:b9:18 brd ff:ff:ff:ff:ff:ff
    vxlan id 5064 group dev cloudbr3 port 32768 61000 ttl 10
ageing 300

VMs on one host can communicate between themselves, but VMs on different
host can not comunicate.

So, is this the right config that I have done - I should have done
everything per documentation.

This is ACS 4.4 clean install, Centos 6.5, elrepo kernel 3.10 and the
bultin iproute2 iproute-2.6.32 for the default kernel - I know I should
have coresponding iproute2 version - but this ones DOES work, as I
confirmed by manually createing vxlan interfaces, and pinging between hosts

Any suggestions ?
