Dear openstack, We are facing a peculiar issue with regards to users quota of resources. e.g: s.no project user instance quota no instance created 1 test - 10 2 test user1 2 2 3 test user2 2 error "quota over" 4 test user3 3 able to create only 1 instance 5 test user4 no user quota defined able to create 10 instance As you see from mentioned table. when user1,user2, has instance quota of 2 and when user1 has created 2 instance, user2 unable to create instance. but user3 able to create only 1 more instance, user 4 has no quota applied so project quota 10 will be applied and he can create 10 instance. the quota is applied to each user but not tracked for each user, so this defeats the purpose of per user quota. Please help us with resolving this issue. Regards, sysadmin team
