Public bug reported:
Sometimes we can not say a cloud deployment has unlimited capacity, especially
for small cluster. And sometimes, cluster expansion takes time. You can not
adjust all users/project quota at once. Then users began to complain, why I
cannot create resource since I still have free quota? Why you change my quota?
Furthermore, a cloud deployment may not have much ability to handle unlimited
resource since the total physical capacity has its ceiling. For instance, there
is no more free capacity of your storage cluster to create more volumes. There
are no more bandwidth for your network cluster to hold more floating IPs. There
are no more vCPUs of compute node to hold more instances.
This RFE propose to add some limitation of neutron to avoid user
creating resource beyond the cluster capacity. So, then cloud
users(providers) can estimate a total capacity limit based on the
cluster size and limit it directly at the initial deployment.
