2015-12-09 03:39:12 -0500 commented question Icehouse to create external net with ODL

did you manage to solve the issue? I have the same problem
2015-12-08 11:05:36 -0500 asked a question net-create mechanism driver error

I just integrated openstack with opendaylight, however after neutron net-create ext-net I get mechanism driver error.

controller@controller-std:~/networking-odl$ neutron net-create ext-net
500-{u'NeutronError': {u'message': u'create_network_postcommit failed.', u'type': u'MechanismDriverError', u'detail': u''}}

Do I need to install networking_odl package? Because I remember I needed this for devstack. If I need this package then, for stable/icehouse I get the following error when sudo python setup.py install:

controller@controller-std:~/networking-odl$ sudo python setup.py install

2015-12-07 05:45:08 -0500 answered a question docker ps -a does not show anything using nova-docker

Solved the problem, in icehouse instead of modifying /etc/nova/nova.conf you should modify /etc/nova/nova-compute.conf to change the compute_driver, and comment out:

# [libvirt]
# virt_type=kvm
2015-12-07 03:26:48 -0500 asked a question docker ps -a does not show anything using nova-docker

Hi,

I just installed nova-docker on my compute node, however after booting a docker container, docker ps -a does not show anything, and of course the container is not pingable. However nova list shows that the container is running. Here is my nova.conf on the compute node:

[DEFAULT]
dhcpbridge_flagfile=/etc/nova/nova.conf
dhcpbridge=/usr/bin/nova-dhcpbridge
logdir=/var/log/nova
state_path=/var/lib/nova
lock_path=/var/lock/nova
force_dhcp_release=True
iscsi_helper=tgtadm
libvirt_use_virtio_for_bridges=True
connection_type=libvirt
root_helper=sudo nova-rootwrap /etc/nova/rootwrap.conf
verbose=True
ec2_private_dns_show_ip=True
api_paste_config=/etc/nova/api-paste.ini
volumes_path=/var/lib/nova/volumes
enabled_apis=ec2,osapi_compute,metadata

compute_driver = novadocker.virt.docker.DockerDriver

network_api_class = nova.network.neutronv2.api.API
neutron_url = http://controller-std:9696
neutron_auth_strategy = keystone
neutron_admin_tenant_name = service
neutron_admin_username = neutron
neutron_admin_password = NEUTRON_PASS
neutron_admin_auth_url = http://controller-std:35357/v2.0
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
security_group_api = neutron

auth_strategy = keystone

rpc_backend = rabbit
rabbit_host = controller-std
rabbit_password = RABBIT_PASS

my_ip = 10.0.0.31
vnc_enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = 10.0.0.31
novncproxy_base_url = http://controller-std:6080/vnc_auto.html

glance_host = controller-std

[database]
# The SQLAlchemy connection string used to connect to the database
connection = mysql://nova:NOVA_DBPASS@controller-std/nova

[keystone_authtoken]
auth_uri = http://controller-std:5000
auth_host = controller-std
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = NOVA_PASS

And this is nova list on controller node:

controller@controller-std:~$ nova list

P.S.: I am using openstack icehouse, and not using heat.

Yeah I can do that, I live in the country on your left :D

Okay thank you so much, without people like you I dont know how I can survive. I really appreciate it.

And I cant ping from network node, 192.168.1.X for instances.
2015-12-05 12:20:36 -0500 commented answer cannot ping 203.0.113.101 icehouse

perhaps I should put higher than 107 for the br-ex because I guess if I create more instances, when it reaches 107 again something will go wrong, isn't it?
2015-12-05 12:20:28 -0500 commented answer cannot ping 203.0.113.101 icehouse

okay now im able to ping 203.0.113.X without qrouter, is qg-xxxxxx external subnet?!
2015-12-05 12:09:13 -0500 commented answer cannot ping 203.0.113.101 icehouse

You mean I change br-ex IP in /etc/network/interfaces?
2015-12-05 11:41:41 -0500 commented answer cannot ping 203.0.113.101 icehouse

through qrouter everything is fine, through instance also everything is fine, however from network node I cannot ping floating IPs, I don't know why
2015-12-05 11:40:28 -0500 commented answer cannot ping 203.0.113.101 icehouse

If I ping through qrouter on Network Node, and run tcpdump on compute node: 

19:37:36.144199 IP 203.0.113.102 > 192.168.1.2: ICMP echo request, id 4984, seq 1, length 64
19:37:36.145220 IP 192.168.1.2 > 203.0.113.102: ICMP echo reply, id 4984, seq 1, length 64

Hi

I followed OpenStack icehouse installation guide (http://docs.openstack.org/icehouse/install-guide/install/apt/openstack-install-guide-apt-icehouse.pdf (here)), However I am not able to ping 203.0.113.101
