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.
