I am currently trying to get Grizzly up and running on CentOS 6.4.
I have followed
as I can and from both a dashboard and OpenStack command line
viewpoint all OpenStack services are up and running and it appears that
VM's can be lauched and stopped without any obvious errors being recorded
but I can't interact with them using things like ping or ssh.
Below is information I think may be useful to fix the issue. Thanks for
any insight you care to share.
Currently I have a single machine running all services
Management Network 10.10.11.2/24 em2
Bridge linked to em1 220.127.116.11/24
We want people to be able to create VM's that they can access via
So as an initial test I follow the example listed in the guide above and
created a demo-net'
Key details below
Then I ran
quantum net-create public --router:external=True
quantum subnet-create --ip_version 4 --gateway 18.104.22.168 public
--disable-dhcp --name public-subnet
quantum router-gateway-set demo-router public
Using this config instances will launch and if I assign a machine to the
public network, the network topology appears to be what we want. But in
the guides section about lauching your first vm (
it states that ip netns should show two pieces of information qrouter
and qdhcp. I am only seeing qrouter.
Should what I have set up work ? Or have I missed something fundamental ?
As it was the default quantum should be configured to use gre + tunnels, I
am using 2.6.32-358.118.1.openstack.el6.x86_64 to add the functionality
that is missing from the default CentOS kernel.
/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini contains the
following, would it be simpler to get what we need using a VLAN
sql_connection = mysql://quantum:firstname.lastname@example.org/quantum
reconnect_interval = 2
tenant_network_type = gre
enable_tunneling = True
tunnel_id_ranges = 1:1000
local_ip = 10.10.11.2
polling_interval = 2
