In 4.14.0, in order to create a VM from the template catalog UI, a ConfigMap named "kubevirt-user-settings" in the default namespace should exist.
If it's not found, the intention was that the UI tries to create it, if the user is a cluster-admin.

The problem is, the user can be a cluster-admin through IdP (Identity Provider), not necessarily the user is the kubeadmin itself (it's not recommended to use this user in production clusters).

When the kubeadmin user is logged in, the ConfigMap is created.
But not if the logged in user is a cluster-admin that has been authorized by IDP Oauth.

4.14.0

100%

1. Start with a cluster with an identity provider and log in with a user who has a cluster-admin permissions.
2. Have CNV 4.13 on the cluster.
3. Upgrade it to 4.14.0 from production (redhat-operators)
4. Try to create a VM from templates catalog

The modal loading is stuck, VM can't be created.

The modal has been completely loaded, and buttons to create the VirtualMachine are available.
