Unable to Delete Network Host Config from UI

Problem

Unable to delete network host config from the UI even if it is not being used by any host.

Environment

  • Private Cloud Director Virtualization - v2025.4 and Higher

  • Self-Hosted Private Cloud Director Kubernetes - v2025.4 and Higher

  • Component**:** Host Configuration Management (resmgr database)

Cause

The host configuration was previously associated with a host that has since been decommissioned. However, a stale mapping entry remains between the host and host configuration in the host_to_hostconfig_map table of the Resmgr database.

This issue is tracked under bug PCD-407 and is now fixed on PCD 2025.6-151 above release, which prevents new stale mappings from being created.

NOTE

Existing stale entries from earlier versions will persist after the upgrade; it's recommended to follow the steps mentioned in the Resolution to delete the stale entries.

Diagnostics

  1. Retrieve the token:

token=$(openstack token issue -f value -c id)

  1. Get the list of host configs:

curl -s -X GET -H "X-Auth-Token: $token" https://<REGION_FQDN>/resmgr/v2/hostconfigs | jq '.[] | {id, name}' # Sample Output: { "id": "[HOSTCONFIG_ID_1]", "name": "[HOSTCONFIG_NAME_1]" } { "id": "[HOSTCONFIG_ID_2]", "name": "[HOSTCONFIG_NAME_2]" } { "id": "[HOSTCONFIG_ID_3]", "name": "[HOSTCONFIG_NAME_3]" }

  1. Get the list of hosts that use the host config that needs to be deleted:

curl -s -X GET -H "X-Auth-Token: $token" https://<REGION_FQDN>/resmgr/v2/hosts | jq -c '.[] | select(.hostconfig_id == "<HOSTCONFIG_ID>") | {id, hostname: .info.hostname, hostconfig_id}' # Sample Output: { "id": "[HOST_ID_1]", "hostname": "[HOSTNAME_1]", "hostconfig_id": "[HOSTCONFIG_ID]" } { "id": "[HOST_ID_2]", "hostname": "[HOSTNAME_2]", "hostconfig_id": "[HOSTCONFIG_ID]" }

Resolution

  1. Delete the stale host config mapping

Info

Run below for each [HOST_ID]returned in the output of command executed in the point number 3 in Diagnostics section

curl -s -X DELETE -H "X-Auth-Token: $token" "https://<REGION_FQDN>/resmgr/v2/hosts/<HOST_ID>/hostconfig/<HOSTCONFIG_ID>"

  1. Delete the host Configuration after removing all the mappings

curl -s -X DELETE \ -H "X-Auth-Token: $token" \ "https://<REGION_FQDN>/resmgr/v2/hostconfigs/<HOSTCONFIG_ID>"

Validation

Check the UI to confirm that the previously stale host configuration no longer appears.
