Why do virtual machines running in OpenShift Virtualization intermittently lose network connection?

Solution Verified - Updated -

Issue

  • Virtual machines that are connected to the Linux bridge are intermittently losing connectivity in OpenShift Virtualization. They regain connectivity if they are migrated to another node or if they are powered down and started back in the same node.
  • The Network Attachment Definition (net-attach-def) was created with preserveDefaultVlan: false.

Environment

  • OpenShift Virtualization 4.14.
