Public bug reported: LibvirtDriver's _get_instance_disk_info calls libvirt_utils.get_disk_backing_file() if processing a qcow2 backing file. If this is a file belonging to an attached and NFS-hosted Cinder volume, it may be owned by qemu:qemu and therefore not readable as the nova user.
My proposed solution is to run the images.qemu_img_info() call as root in this case. Note that this requires a change to grenade to upgrade the rootwrap configuration for gating to pass. ** Affects: nova Importance: Undecided Assignee: Eric Harney (eharney) Status: In Progress -- You received this bug notification because you are a member of Yahoo!
