Unable to attach a reserve static internal IP to a vm

Question

VM-A is using network-A. I want to assign static-internal-IP-A for VM-A.

/--Method 1--/

1. Clicked on VM-A
2. Update network interfaces network-A
3. Under Internal IP dropdown option, it shows Automatic and Custom. (I do remember seeing the Create IP option a couple of times but I can't reproduce the steps to have this option again)

/--Method 2--/

1. Clicked on network-A
2. Under Reserve Static Internal IP Address tab, reserve static-internal-IP-A
3. Repeat steps in Method 1 again
4. The static-internal-IP-A option does not show up

Which steps have I missed?

Answer 1

You can't set a reserved internal IP to an existing compute engine. You have to create another VM or another network interface for this VM.
