We don't currently have a way of expressing resource requests within a given instancetype and instead can only express the user visible resources for CPU and Memory, for example:

apiVersion: instancetype.kubevirt.io/v1alpha2
kind: VirtualMachineInstancetype
metadata:
  name: csmall
spec:
  cpu:
    guest: 1
  memory:
    guest: 128Mi

It would be useful to be able to express resource requests as we can directly via the DomainSpec via something like :

apiVersion: instancetype.kubevirt.io/v1alpha2
kind: VirtualMachineInstancetype
metadata:
  name: csmall
spec:
  resources:

    requests:

      cpu: 100m

      memory: 128Mi    

This would be mutually exclusive with the guest visible approach and should cause the creation or update of an instancetype to be rejected if both are present.
