Getting started with Openstack here. I've successfully imported and launched instances with a cirros image per the Openstack Installation Guide, but when I import UEC images, like this one here and then attempt to launch instances from it, the instance console reports:
Booting from Hard Disk... Boot failed: not a bootable disk
No bootable device.
When importing the UEC image, I've tried specifying both RAW and QCOW2 formats to Openstack, but get the same error.
What am I missing here?
