hi

even i encountered the same problem, while troubleshooting i came to know that in /var/log/nova/nova-compute.log qemu-image is showing error.
which means the image which you used in glance is not qemu compatible so i changed that image n freshly downloaded.

apart from that there will be following few types of error you encounter as per my knowledge.

1. ‘Not authorized for image’

/var/log/nova-­‐compute.log.


Log must be displaying error. This is clear issue of missing configuration on authentication part.
Please look at you

/etc/nova/nova.conf

2. ‘compute2hostnotfound’


You may find the error like
‘compute2hostnotfound’.
It clearly means that either compute host is not reachable or compute service is down.
Ensure that ‘nova-­‐compute’ service is running successfully on compute boxes.
e.g service nova-­‐compute restart. Please do verify in every machine.

 3. No support for os type kvm
You may see error like in

/var/log/libvirt/libvirtd.log


4.kvm/qemu issues.
