Environment

VMware Cloud Director for Service Provider 10.x

Cause

Name of the VM has an extra space at the end.

Name of the computer contains underscores. 

Resolution

• Edit the VM name and remove the extra space at the end of the name.
• Vm name can have the spaces in the middle of its strings but not at the end of the name.

Valid Entry: [VM Name]

Invalid entry: [VM Name ]

• VMware Cloud Director uses DNS rules for computer names. DNS names can contain only alphabetic characters (A-Z), numeric characters (0-9), the minus sign (-), and the period (.).
• Do not use underscores in computer names.

Valid Entry: [VMName] 

Eg: Testvm01

Invalid entry: [VM_Name]

Eg: Test_vm01

Additional Information

Impact/Risks:

The name of the VM is not matching with the entry in the DB, so when we try to edit the VM properties the errors regarding the string is encountered.
