Hi all,

I am currently exploring Openstack. I've created an Ubuntu 12.04 LTS image using Virtual Machine Manager. I created it using the default options of the Virtual Machine Manager. I stepped on to the installation of the VM and just provided a very simple username and password credentials. The image was successfully created and stored under /var/lib/libvirt/images. After that, I've uploaded the image to openstack using this:

glance image-create --name "ubu0-kvm-img-1" --disk-format=raw --container-format=bare < {filepath}.img

Uploading was successful based on this return:

Also, I can view it from the openstack dashboard. Unfortunately, I have no enough karma yet to upload the snapshot. After that, I created an instance using that image and creation was successful, signified by the "running" state of the instance. It was given an IP of I pinged it from the host machine and it can be reached. However, I cannot access it using SSH or remina or the console from the openstack dashboard. I tried to assign a floating IP and restarted it. However, this did not solve the problem.

Do you have any ideas on how to resolve this? Any feedback is greatly appreciated. Thanks in advance!

You don't need to upload images from the dashboard; the output of the command line tools (e.g., `glance index`) is sufficient.

Check that sshd is installed and running on the virtual image you created. In order to debug the issue, you may want to try running one of the images known to be working, like the CirrOS one: if you can connect to that, via vnc or ssh, then the trouble is in the image you created. Otherwise the problem is somewhere else.
