Unable to Delete Network Host Config from UI

Problem

Unable to delete network host config from the UI, even if the host is not using it.

Environment

• Private Cloud Director Virtualization - till 2025.4-497

• Self-Hosted Private Cloud Director Kubernetes - till 2025.4-497

• Component: Blueprint

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 the host configuration in the host_to_hostconfig_map table of the Resource Manager database.

This issue is tracked under bug PCD-407 and is now fixed in PCD 2025.6-151 and later releases, which prevent new stale mappings from being created.

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

Workaround

• Retrieve the token:

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

• Get the list of host configs:

curl -s -X GET   -H "X-Auth-Token: $token"   https://<PCD_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]"
}

• 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://<PCD_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]"
}

• Delete the stale host config mapping. Run below for each [HOST_ID]returned in the output of the command executed in the above output

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

• Delete the host Configuration after removing all the mappings

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

Validation

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