cnv-must-gather is a tool built on top of OpenShift must-gather that expands its capabilities to gather Container-Native Virtualization information.

oc adm must-gather --image=quay.io/jsaucier/cnv-must-gather

The command above will create a local directory with a dump of the CNV state. Note that this command will only get data related to the CNV part of the OpenShift cluster.

You will get a dump of:

• The Hyperconverged Cluster Operator namespaces (and its children objects)
• All namespaces (and their children objects) that belong to any CNV resources
• All CNV CRD's definitions
• All namspaces that contains VMs
• All VMs definition

In order to get data about other parts of the cluster (not specific to CNV) you should run oc adm must-gather (without passing a custom image). Run oc adm must-gather -h to see more options.
