Hi Gabriel, I use Diablo and I have a similar behavior. If I clean the cache instances on the compute nodes and I run a VM with a big image (I used a 20Gbytes image) while the image is copied from glance to the compute node the dashboard looks to be freezed or very slow. The problem is in 'glance-api', while the image is transfered it takes a long time to handle the requests. I resolved the problem bypassing 'glance-api'. I used an ftp server to manage the data transfer so the 'glance-api' is not overloaded. Andrea.
