VM Settings validation blocks custom key value pairs #7700

ISSUE TYPE

• Improvement Request

COMPONENT NAME

UI

CLOUDSTACK VERSION

4.17,4.18 mostly related to the new UI. 

CONFIGURATION

OS / ENVIRONMENT

SUMMARY

Currently, the VM settings in the UI validate (not in API) the parameters. It allows only a known/predefined list of parameters in the drop-down available. However, this is restrictive for advanced users and more use cases. Custom parameter/key-value pairs could be allowed if required to display a message that it is not in the predefined list and the user is expected to make sure it is supported etc.

STEPS TO REPRODUCE

1. Stop a VM
2. Try adding a new parameter via the VM settings tab.

EXPECTED RESULTS

VM settings UI could allow custom key-value pairs. 

ACTUAL RESULTS

VM settings UI doesn't allow custom key-value pairs.
