Description of problem:

[1] Created a VM with below resources.limit.memory and resources.requests.memory.

~~~

1. oc get vm rhel7-forward-rook -o yaml |yq -y '.spec.template.spec.domain.resources'
   limits:
   memory: 5Gi
   requests:
   memory: 4Gi
   ~~~

The namespace has got Max Limit/Request Ratio for memory set to 2.

~~~

1. oc describe limits
   Name: resource-limits
   Namespace: nijin-cnv
   Type Resource Min Max Default Request Default Limit Max Limit/Request Ratio
   • • • -------- — — --------------- ------------- -----------------------
         Container cpu - 2 2 2 -
         Container memory - 8Gi 4Gi 4Gi 2 <<<
         ~~~

[2] Increased the VM memory to 5 Gi from the web UI.

~~~
Click on VM => Details => Edit CPU | Memory
~~~

This only increased the requests and not the limits.

~~~

1. oc get vm rhel7-forward-rook -o yaml|yq -y '.spec.template.spec.domain.resources'
   limits:
   memory: 5Gi
   requests:
   memory: 5Gi
   ~~~

VM will start since the ratio is 1 less than maxLimitRequestRatio.

[3] Decreased the VM memory to 2 Gi from web UI and now, the VM startup fails with the error below because the ratio is more than 2:

~~~
Click on VM => Details => Edit CPU | Memory
~~~

~~~
5s Warning FailedCreate virtualmachineinstance/rhel7-forward-rook (combined from similar events): Error creating pod: pods "virt-launcher-rhel7-forward-rook-f78gg" is forbidden: memory max limit to request ratio per Container is 2, but provided ratio is 2.342071
~~~

In [2] and [3], there is no option to mention the limits. Also, it doesn't increase the limits automatically in proportion to the increase in requests.

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

OpenShift Virtualization 4.11.0

How reproducible:

100%

Steps to Reproduce:

Please refer above.

Actual results:

Limits are not changed/no options to change the limits while increasing/decreasing the virtual machine resources from GUI

Expected results:

The customer is expecting to decrease/increase the limits in proportion to the increase/decrease of the requests.
