How I can find or set entity_version,spec_version,spec_hash?

@MaheshNikam To get the spec_version and entity_version, you will need to first use the GET REST API call for VM (https://AddressOfServer:9440/api/nutanix/v3/vms/{VM-UUID} ), and once you get those details, you can then use it in the above-mentioned PUT API call for updating VMs via REST API. 

Hi !

Even though i’m able to get all VM details through GET REST API Call, i’m actually not able to update only one property.

How can you update specifical property you retrieved (ex: category, disk size etc...)?

 

Thanks a lot :)
