### Cannot create instance: Cannot Find ext4 filesystem on compute node?

Hello,

I am having an issue with my compute node the moment I launch an instance. Regardless of whether I launch via ephemeral storage or a bootable volume it ends up going into error as well as displaying an error message on the compute node stating that it cannot find the ext4 filesystem.

See hee: Error Message

I am not sure why I keep getting this issue. I have already set up two compute nodes using the video tutorials thinking I missed a step or misconfigured something but the issue remains.

Not sure what to do. This appears to show a similar issue, but no solution.

Also, I do not see the libvirt service running when I do a nova-manage service list this is what I see

Is the node configuration (drive configuration in particular) require a special configuration that I missed

Here are my configuration files (if it helps):

Controller Node:

nova.conf : http://paste.ubuntu.com/10143131/

Compute Node:

nova.conf : http://paste.ubuntu.com/10143173/

If you all need any more info just let me know. Any help, would be greatly appreciated.
