Bug 2239915

Description of problem:
 After adding autoCPULimitNamespaceLabelSelector to the Kubevirt - all VMs set resources.limits.cpu automatically. I created VMMRQ for allocating additional resources during the migration, but it does not help - the migration is still in Pending state.

VM and VMI have resources.requests only:

>  oc get vm vm-fedora-cpu-auto-lim -o json | jq .spec.template.spec.domain.resources
> {
>  "requests": {
>    "cpu": "1",
>    "memory": "1Gi"
>  }
> }

The POD has requests and limits (because of auto CPU limits set):

> $ oc get pod virt-launcher-vm-fedora-cpu-auto-lim-qdj5q -o json | jq .spec.containers[0].resources
> {
>   "limits": {
>     "cpu": "1",
>   },
>   "requests": {
>     "cpu": "1",
>   }
> }

The CPU usage is very close to resource quota:

> $ oc get resourcequota
> NAME        AGE   REQUEST                     LIMIT
> quota-cpu   80m   requests.cpu: 1001m/1100m   limits.cpu: 1010m/1100m

Created VMMRQ with additional cpu:

> $ oc get vmmrq  my-vmmrq-cpu-4 -o json | jq .spec
> {
>   "additionalMigrationResources": {
>     "limits.cpu": 4,
>     "requests.cpu": 4
>   }
> }

However, the migration still in Pending state:

> $ oc get vmim
> NAME                        PHASE     VMI
> kubevirt-migrate-vm-kd2rh   Pending   vm-fedora-cpu-auto-lim


Version-Release number of selected component (if applicable):
4.14

How reproducible:
100%

Steps to Reproduce:
1. enable autoCPULimitNamespaceLabelSelector in HCO
2. create resourcequota with request and limits
3. create VM with cpu request, but without limits
4. create vmmrq with resource and limits
5. migrate VM

Actual results:
 Migration is in Pending state

Expected results:
 Migration completed
