Public bug reported:

If user want to boot in uefi, they need to specify uefi loader path.
But currently nova will only access to /usr/share/OVMF/OVMF_CODE.fd.
However libvirt forbid access to /usr/share before following patch.
https://github.com/libvirt/libvirt/commit/2f01cfdf05448513d150ff1914d3444161c531b9
The patch was merged since livirt 1.2.19.
Default package for older os release such as ubuntu trusty didn't merge the patch yet.
Therefore those vm will created failed at access validation check.

Maybe we should add one uefi option for uefi loader path instead of static code in following link.
