I successfully launched an instance. However, I could not ping or ssh into that running instance. By viewing the instance's console log, I found out that

Booting from hard disk
Boot failed. not a bootable disk
Booting from ROM
DHCP (net0: fa:16:3e:3e: 23:aa:bd)
No more network drivers
Booting from floppy
Boot failed. Could not read from the boot disk.
No boot table device

Openstack dashboard shows that the instance is running without any errors (status is Active). What is wrong about the image? why it is running but its log is saying it is not bootable?

How did you make the image?

I am also having this problem. Yashjit, did you find a solution? I am using RDO and have uploaded a CentOS 6.4 - minimal iso. I know the iso is good, (there is a CirrOS image that comes with RDO and I experience the same thing.) I am new to openstack, but also ran into this issue when going through the install guide on It seems like there is something simple that I am missing or haven't done. Which logs might point me in the right direction? Thanks!

I had the same issue. I was directly importing an xz compressed image (e.g. ( Upon import, it looks like openstack thought it was raw even though I marked it as qcow2. Try downloading it and uncompressing it first, then importing the image into glance, that worked for me.

From the comment I could see that you are directly uploading a normal iso image.

Openstack images have to satisfy few requirements. You can see it here

Hence you need to build a cloud image manually. Ref: (Basically you will be installing the os from iso to a vm, install cloud-init packages and then convert that vm to a image)

If you are tired of doing these, you can download images specifically build for openstack.
