From 6027abb96369a30e6ccd3f747f4029e36232c0af Mon Sep 17 00:00:00 2001 From: Todd Malsbary Date: Thu, 9 Sep 2021 11:24:45 -0700 Subject: Fix KubeVirt and SR-IOV addon interaction SR-IOV wants to drain the nodes during reconciliation of SriovNetwork resources, while KubeVirt wants to keep at least one instance running at all times via a PodDisruptionBudget. KubeVirt's behavior is not customizable, so split the addons into different composite apps that allow finer control of the instantiation order.
