Open Stack

Hi Britt,

Thanks for the answer.

I am using Virtual machine(KVM) for openstack installation. Its a single
node installation.

Now i can create instance from openstack dahboard and and can login in to
the instance from dashboard konsole.

But i couln't connect to instance from controller node.

Also i couldn't have connection between instances.

Ifconfig output from openstack installation node
