OpenStack Configuration Notes
1. If you are using all-in-one deployment or a scenario with only one available compute node make
sure that you have set both allow_resize_to_same_host and allow_migrate_to_same_host to
“true” in configuration file at /etc/nova/nova.conf.
Tip These options allow you to resize the instance on one node.
Set resize_confrim_window=x. By default, this is set to 0, but you need to change this to x seconds
in order to automatically confirm the resize after x seconds.
2. If you are running OpenStack within a virtual machine set, in order to use QEMU you must set the
following options in configuration file on your compute host(s) at /etc/nova/nova.conf:
libvirt_type=qemu
Cinder service=mandatory
Note Configuration changes are applied only after the restart of Nova services.
3. If you would like OpenStack to report debugging information into an httpd log file, specify the
following parameters in the configuration files found at /etc/openstack-dashboard/local_settings:
DEBUG=True
TEMPLATE_DEBUG=DEBUG
Note The file may be a significant size; this may negatively affect performance.
4. Check that you have opened all necessary ports in your firewall:
8776 - Block Storage (cinder)
8774 - Compute (nova) endpoints
5000 - Identity service public endpoint
9696- Networking (neutron)
5672 - Message Broker (AMQP traffic)
Tip For the correct steps needed to install the OpenStack solution on your environment, refer to the
OpenStack documentation located on the OpenStack website at: http://docs.openstack.org/.
