There is an error while editing the CPU|Memory if the VM is created from instanceTypes:
Error "VM field conflicts with selected Instancetype" for field "spec.template.spec.domain.cpu".

I think it should be caused by the same reason as this bug, so update it here.

This sounds like a valid UI bug, this value should come from the associated instance type.

This isn't a bug. You can't edit (update/patch) the CPU or Memory of the VM when using instance types, see the following docs for more details:

@Guohua

When the VirtualMachine resource is created, the spec is updated with the calculated ControllerRevision references.

apiVersion: kubevirt.io/v1
kind: VirtualMachine
metadata:
name: vm-instancetype-0-0
namespace: default
spec:
instancetype:
kind: VirtualMachineInstancetype
name: server.small
revisionName: vm-instancetype-0-0-server.small-17f33b62-d43f-43a4-ad32-f0d178a672d8-1 # New field added after VM creation
preference:
kind: VirtualMachinePreference
name: fedora
revisionName: vm-instancetype-0-0-fedora-13275565-0963-4b65-82eb-5bac6875f9b6-1 # New field added after VM creation

The ControllerRevision(s) will contain the relevant data the UI needs to pick up for display, it will not be shown in the VM for reasons stated above by Lee.

apiVersion: apps/v1
kind: ControllerRevision
data:
apiVersion: instancetype.kubevirt.io/v1alpha2
kind: VirtualMachineInstancetype
metadata:
name: server.small
namespace: default
spec:
cpu:
guest: 1
memory:
guest: 2Gi

The message "CPU and Memory can not be edited if the VirtualMachine is created from InstanceType" is added to VM details tab.

But on VM overview tab, the CPU|Memory field is keeping in loading, maybe we should just leave it blank.

It should show the same number we see in catalog -> instanceTypes -> VM details
