I have VM images stored locally on my system. Is there any way I could launch the instances without uploading them to glance or using them as Cinder volumes ?

First, you must check type of existing VM image, you can use
qemu-img info {image_path}for that purpose, and then create cinder volume with size of RAW image (qemu-img info show it).Second, if image type has RAW type, run:
dd if={image_path} of={volume_path-volume_id},if image has other format do:
Third, you must set bootable flag for this volume (with command-line or horizon).
Fourthly, boot instance from this volume.
{image_path}- is path to VM image on file system, like:/tmp/images/my-vm-image.iso{volume_path-volume_id}- is path to cinder volume on file system, like:/dev/mapper/data-volume--blabla--cinder--volume--idfor LVM or/mnt/nfs/volume-blabla-cinder-volume-idfor NFS.
