Package does not contain SQL Table needed for the Veeam Integration

[MarceldeGierIS]

Environment

• Apache CloudStack: 4.22.0.0-shapeblue01
• Repository: http://packages.shapeblue.com/cloudstack/custompublic/lemur/el9/4.22/
• OS: Rocky Linux 9
• Packages:
  • cloudstack-management-4.22.0.0-shapeblue01
  • cloudstack-common-4.22.0.0-shapeblue01
  • cloudstack-usage-4.22.0.0-shapeblue01
• Upgraded from 4.22.0 (Cloudstack Repository)

Description
When enabling the new Veeam Control Service (integration.veeam.control.enabled=true), the CloudStack Management Server fails to start the Veeam Control API service.

The failure is caused by a missing database table:

Table 'cloud.management_server_details' doesn't exist

The Veeam Control Service continues to load, but the API server itself is not started.

Relevant Log Output

ERROR [o.a.c.v.VeeamControlServiceImpl]
Failed to start Veeam Control API server, continuing without it

com.cloud.utils.exception.CloudRuntimeException:
Unable to find on DB, due to:
Table 'cloud.management_server_details' doesn't exist

Stack trace references:

org.apache.cloudstack.veeam.VeeamControlServer.startIfEnabled(VeeamControlServer.java:83)
org.apache.cloudstack.veeam.VeeamControlServiceImpl.start(VeeamControlServiceImpl.java:114)

Investigation Performed
Veeam Control Service classes are present

The package contains the Veeam Control Service implementation:

org/apache/cloudstack/veeam/VeeamControlServiceImpl.class
org/apache/cloudstack/veeam/VeeamControlServer.class

It also contains:

com/cloud/cluster/dao/ManagementServerHostDetailsDao.class
com/cloud/cluster/dao/ManagementServerHostDetailsDaoImpl.class

which appear to require the missing table.

No schema definition found
We searched all delivered SQL and schema files:

grep -Rni "management_server_details" \
  /usr/share/cloudstack-management/setup \
  /usr/share/cloudstack-management/lib \
  /usr/share/cloudstack-common

Result:

No matches found

We also searched specifically for table creation statements:

grep -Rni "CREATE TABLE.*management_server_details" \
  /usr/share/cloudstack-management/setup

Result:

No matches found

Expected Behaviour
When Veeam Control Service is enabled the service should start successfully and all required database objects should be available through either:

• create-schema.sql (fresh install), or
• an upgrade migration script.

Actual Behaviour
The service fails to start because the required table does not exist and no schema migration appears to be provided.

Questions

1. Is management_server_details intentionally omitted from the current Lemur build?
2. Is there a missing schema migration or upgrade script?
3. Can you provide the expected DDL for this table?
4. Is this a known issue in the current Lemur preview packages?

Thank you.

Hi @MarceldeGierIS - thanks for reporting the issue.

In this case since you have upgraded from 4.22.0 CloudStack is indeed missing the Veeam tables as the upgrade mechanism is not triggered between packages on the same version (this is not observed on fresh install or upgrade from 4.21 or lower versions). The Technical Preview build is designed for fresh installations only. Upgrades are supported only from CloudStack 4.21.x or earlier. We will update the Technical Preview documentation to clearly highlight these version constraints and cover upgrade scenarios.

As a workaround for your current deployment, please perform the following steps to manually add the missing Veeam database schema:

• Stop the management-server service on your CloudStack management servers
• Apply the following SQL statements on the cloud DB schema:

-- Add management_server_details table to allow ManagementServer scope configs
CREATE TABLE IF NOT EXISTS `management_server_details` (
    `id` bigint unsigned NOT NULL AUTO_INCREMENT COMMENT 'id',
    `management_server_id` bigint unsigned NOT NULL COMMENT 'management server the detail is related to',
    `name` varchar(255) NOT NULL COMMENT 'name of the detail',
    `value` varchar(255) NOT NULL,
    `display` tinyint(1) NOT NULL DEFAULT '1' COMMENT 'True if the detail can be displayed to the end user',
    PRIMARY KEY (`id`),
    CONSTRAINT `fk_management_server_details__management_server_id` FOREIGN KEY `fk_management_server_details__management_server_id`(`management_server_id`) REFERENCES `mshost`(`id`) ON DELETE CASCADE,
    KEY `i_management_server_details__name__value` (`name`(128),`value`(128))
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;


-- Add checkpoint tracking fields to backups table for incremental backup support
CALL `cloud`.`IDEMPOTENT_ADD_COLUMN`('cloud.backups', 'from_checkpoint_id', 'VARCHAR(255) DEFAULT NULL COMMENT "Previous active checkpoint id for incremental backups"');
CALL `cloud`.`IDEMPOTENT_ADD_COLUMN`('cloud.backups', 'to_checkpoint_id', 'VARCHAR(255) DEFAULT NULL COMMENT "New checkpoint id created for the next incremental backup"');
CALL `cloud`.`IDEMPOTENT_ADD_COLUMN`('cloud.backups', 'checkpoint_create_time', 'BIGINT DEFAULT NULL COMMENT "Checkpoint creation timestamp from libvirt"');
CALL `cloud`.`IDEMPOTENT_ADD_COLUMN`('cloud.backups', 'host_id', 'BIGINT UNSIGNED DEFAULT NULL COMMENT "Host where backup is running"');

-- Create image_transfer table for per-disk image transfers
CREATE TABLE IF NOT EXISTS `cloud`.`image_transfer`(
    `id` bigint unsigned NOT NULL auto_increment COMMENT 'id',
    `uuid` varchar(40) NOT NULL COMMENT 'uuid',
    `account_id` bigint unsigned NOT NULL COMMENT 'Account ID',
    `domain_id` bigint unsigned NOT NULL COMMENT 'Domain ID',
    `data_center_id` bigint unsigned NOT NULL COMMENT 'Data Center ID',

    `progress` int COMMENT 'Transfer progress percentage (0-100)',
    `signed_ticket_id` varchar(255) COMMENT 'Signed ticket ID from ImageIO',
    `created` datetime NOT NULL COMMENT 'date created',
    `updated` datetime COMMENT 'date updated if not null',
    `removed` datetime COMMENT 'date removed if not null',
    PRIMARY KEY (`id`),
    UNIQUE KEY `uuid` (`uuid`),
    CONSTRAINT `fk_image_transfer__backup_id` FOREIGN KEY (`backup_id`) REFERENCES `backups`(`id`) ON DELETE CASCADE,
    CONSTRAINT `fk_image_transfer__volume_id` FOREIGN KEY (`volume_id`) REFERENCES `volumes`(`id`) ON DELETE CASCADE,
    CONSTRAINT `fk_image_transfer__host_id` FOREIGN KEY (`host_id`) REFERENCES `host`(`id`) ON DELETE CASCADE,
    INDEX `i_image_transfer__backup_id`(`backup_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

• Start again the management-server service on your CloudStack management servers

Thank you, that works. Are there possibly some other SQL tables missing?

In the UI I'm getting an error about:
Request failed. (530)
Unable to find on DB, due to: Unknown column 'user_vm_view.guest_os_display_name' in 'field list'

Thanks @MarceldeGierIS, sorry we missed that one.

Please consider updating the conflicting view by executing the following on the cloud DB schema:

DROP VIEW IF EXISTS `cloud`.`user_vm_view`;

Thanks, got the interface working again.

I've added the Cloudstack Management node in the Veeam oVirt KVM Inventory. I've configured it to use the Root Admin ID, but when I rescan it, it shows 0 VM's found.

Is there any specific log I should check for errors on the Management Node?

I also noticed a new version is available, is it possible to provide some kind of changelog if any new versions come out? That way we can check if there are any issues fixed, before posting here.

Edit 2026-06-09 09:51:
Found some logging, which shows no errors/warnings:

@MarceldeGierIS Based on the logs, Veeam Control Service is running fine.
Can you please check what is the output of the /vms endpoint,

curl -k 'https://<IP>:8090/ovirt-engine/api/vms' \
  --user '<USERNAME>:<PASSWORD>' \
  --header 'Accept: application/json'

Are the KVM VMs using NFS or SharedMountPoint storage?
