do you plan to rename the vm in case the name already exists or just
abort the creation? i would choose the second

i don't i would love to have it, i would share if i have it

it think it should be done at tenant level, my use case is i want to
restrict vm names depending on the tenant them are in

example:

tenant foo, vm names allowes

foo-mysql-n
foo-apache-n

tenant bar

foo-mongodb-n
foo-nginx

this help a lot with orchestration, we are doing it manually now but i
would like to enforce it
