      +++ This bug was initially created as a clone of Bug #2078545 +++

      Description of problem:
      There are many alerts KubeVirtComponentExceedsRequestedMemory in Firing state on a cluster, some of them appeared right after installation.
      May be memory should be adjusted for kubevirt system pods?

      Version-Release number of selected component (if applicable):
      4.10.7

      Actual results:
      Alerts are constantly firing, some of them triggered right after cluster installation. Screenshot attached

      Expected results:
      kubevirt system pods requested enough memory and alert is not triggered

      Alerts were firing since the clusters were updated to 4.10, and they are present currently.
