Open Stack

Hi guys,

I've got openstack essex configured with vlanmanager and an external
gateway and all my networking runs ok generally.

However, I'm trying to setup Linux HA on two instances. They run on
separate compute nodes and can see each other just fine. hb_takeover and
hb_standby works perfectly. The problem is that nothing outside of the
instance with the HA IP address can connect to it.

It seems that something is ignoring the arp is-at from the instance. Doing
a tcpdump on the compute node's bridged network and the instance's eth0 I
can arp requests and responses fine for its main IP, but when I try to get
to the alias address, I see arp requests only on the compute side. On the
instance side I see it responding, but this doesn't show up on the bridged
interface on the compute node.

Has anyone seen this before? My google-fu is failing to find anything.

Kind regards

 -- joe.
