What is the issue ?why I am not able to launch from dashboard?please help your cinder sotrage is likel not that fast and the windows image is much larger then the other images so its takeing longer then our default timeout to create the volume. im assuming your using somthing like the cinder LVM backend.

try adding  [DEFAULT] block_device_allocate_retries_interval=10 to your nova.conf or nova-cpu.conf if this is a devstack install if you look in the cinder driver log you will likely see its still creating the volume form the image and if you use htop/ps on the host with the cinder volume driver you will see the qemu-img command running. other ways to work around this is to confgiure glance to use cider for image storage that will allow the cinder backend to create a volumn snapshot for the new volume instaed of making a full copy. over all that is much more effeicnt and works similar to when you use ceph for both glance and cinder.

me.
