Inability to create a vm through horizon

Issue

• The requested instance cannot be launched. The following requested resource(s) exceed quota(s): Cores(Available: 0, Requested: 1).

• On other tenants this works as expected, but on this particular one it fails from UI, but works from CLI.

  • Quotas are as follows:
