[Bug 1263338] [NEW] neutron (devstack) network connections to launched instances fail
Public bug reported:
When running neutron on devstack, I run into the issue where I can
successfully launch an instance, but cannot connect to it, not even from
the host running devstack. Commands like 'ping' and 'ssh' appear to get
no response at all.
Steps to reproduce:
./stack.sh

export OS_PASSWORD=password
export OS_TENANT_NAME=demo
export OS_AUTH_URL=http://192.168.126.142:5000/v2.0/

Title:
neutron (devstack) network connections to launched instances fail
Status in OpenStack Neutron (virtual network service):
New
Bug description:
When running neutron on devstack, I run into the issue where I can
successfully launch an instance, but cannot connect to it, not even
from the host running devstack. Commands like 'ping' and 'ssh' appear
to get no response at all.
Steps to reproduce:
./stack.sh

When I ping the instance (10.0.0.3) from the host I run openstack on
(localhost.localdomain, 192.168.126.142) I dont see any arp
request/reply packets on any of the interfaces:
sudo tcpdump -vv -i br-int arp
