Description of problem:
when I try to run an instance with a flavor which is too small the error that I get from Horizon is no available compute found
the compute log shows that the issue is: FlavorDiskTooSmall
The error should be fixed since no available computes is a message that requires a user to call Admin while FlavorDiskTooSmall is something they can try to fix themselves.
I would also add that the flavor is X and the disk size is Y to help the user out...
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. create an image with a min disk size of 80G
2. try to run an instance using a small flavour.
the error we get in horizon is no compute available.
The nova log shows that it's actually a min disk size issue
the error is misleading and suggests that there is a problem with the compute while the problem is actually with the selection of a flavour and can be solved in user's end without involving admin.
