We would like to escalate this defect as it block us to test hotplug feature. For 2.6 the hotplug feature is still in alpha, so not enabled by default. You can enable it manually and it should work though Test on latest hco-bundle-registry-container-v2.6.0-454, HotplugVolumes feature gate could be enabled/disabled when setting the flag true/false in hco cr.
verify steps:
1. Enable the HotplugVolumes flag in hco cr
----------8<-----------
spec:
bareMetalPlatform: true
featureGates:
HotplugVolumes: true
infra: {}
version: v2.6.0
workloads: {}
----------8<-----------
2. Check the configmap
$ oc get configmap kubevirt-config -o yaml -n openshift-cnv
apiVersion: v1
data:
default-network-interface: masquerade
feature-gates: DataVolumes,SRIOV,LiveMigration,CPUManager,CPUNodeDiscovery,Sidecar,Snapshot,HotplugVolumes
We had to change the feature gate implementation in HCO, in order to be able to get better documentation; see https://github.com/kubevirt/hyperconverged-cluster-operator/pull/1060 and https://github.com/kubevirt/hyperconverged-cluster-operator/pull/1062 That cause a small API change: "HotplugVolumes" was changed to "hotplugVolumes" (starts with lower case; to get a valid json/yaml tag) @Nahshon Unna-Tsameret Thanks for letting us know Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
