Qcow2 images may be mounted via qemu-nbd util. It shares image through kernel network block device protocol and this allows to mount it:

modprobe nbd max_part=63
qemu-nbd -c /dev/nbd0 image.qcow2
mkdir -p /mnt/image
mount /dev/nbd0p1 /mnt/image
cat /mnt/image/etc/cloud/cloud.cfg

Great! Thank you dbaxps. I brought the image up in single user mode and then was able to change the password.

In general, ssh keypair gets involved in cloud instance creation. Say oskey.pem, then
$ssh -i oskey.pem cloud-user@floating-ip
will log you in
