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.

Diagnostics

1. Retrieve the token:

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

2. 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]"

}

3. 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

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

2. 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.
