In the interim you can set vpn_image_id to the UUID of an image that you want launched without mac and IP spoofing filters created.  On the compute node the instance is launched with the nova-vpn ruleset which allows DHCP traffic.

At current this only works with a single image UUID.

Hi Joe,
nova network filtering rules are preventing ip-spoofing.
There is a proposal to modify this behavior when using HA in instances.
See thread:
[openstack-dev] VM level HA. Changes in firewall.py question.

You can check with:
virsh nwfilter-dumpxml nova-base

cheers,
Belmiro

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.
