Version:
rhv = 4.4.6

$ openshift-install version
4.8.0-0.nightly-2021-06-01-043518 

Platform:
ocp on rhv

steps:
1) run ./openshift-install create install-config --dir= <anydir>
2) answer the question and in Engine FQDN[:PORT] fill correct FQDN
3) in 'Would you like to use the above certificate to connect to the Engine? ' answer y
4) on 'Engine username' press enter

actual:
'Engine username' question appears 3 times, and then 'Engine FQDN[:PORT]' question appears again. 

./openshift-install create install-config doesn't work if ovirt-config.yaml doesn't exist and user should fill the FQDN URL 

expected: 
Engine username question should appear only one time and then next question
