Openstack+ Shared Storage(NFS) +Permission denied

While setting up Openstack with shared storage , If we get following error while creating a instance ensure that the server is in permissive selinux mode with

getenfonce

and if that too doesn't work try giving 755 permission to the mounted directory here its /var/lib/nova

At last if nothing else worked , tell libvirtd/qemu to use root user to access datas.
[root@compute nova]# cat /etc/libvirt/qemu.conf |grep root

Openstack Icehouse - VNC console not connecting to server

Make sure that the setting in the controller and compute node are correct and also double check the IP's.  And replace the host-name with the IP.

Openstack Icehouse Part 6 : Testing the Setup + Horizon

Creating the Key

$ ssh-keygen

Add the public key to your OpenStack environment:
$ nova keypair-add --pub-key ~/.ssh/id_rsa.pub demo-key

Verify addition of the public key:
$ nova keypair-list
+----------+-------------------------------------------------+
| Name | Fingerprint |
+----------+-------------------------------------------------+
| demo-key | 6c:74:ec:3a:08:05:4e:9e:21:22:a6:dd:b2:62:b8:28 |

+--------------------------------------+---------------------+--------+--------+
Your first instance uses the cirros-0.3.2-x86_64 image.

List available networks:

+--------------------------------------+----------+-------------------------------------------------------+
Your first instance uses the demo-net tenant network. However, you must reference this network using the ID instead of the name.

List available security groups:

$ nova secgroup-list

Creating a New flavor

nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=8cc217b0-96a6-4e98-a901-a694ebff173f --security-group default --key-name demo-key demo-instance1

Creating the instance from back end

nova boot --poll --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=69c6ca95-2f5d-4173-8973-164c5129cb27 --security-group default --key-name Chumma demo-instance

 

Install Horizone on Controller Node

yum install memcached python-memcached mod_wsgi openstack-dashboard

Edit /etc/openstack-dashboard/local_settings:

ALLOWED_HOSTS = ['localhost', 'my-desktop']
service httpd start
