This document provides a list of quick answers to issues caused by incorrect configuration.
No events are available in Abiquo.
Check the default_outbound_api_user in Abiquo. You may need to configure some of the M properties in the abiquo.properties file on the server where M will run. By default, M runs on the Abiquo Server. The API location is required and if you change the M user or password, you must update the M user account details . See Troubleshooting Events and Outbound API Configuration
No events except those related to roles are displayed.
Verify that you correctly configured the network when you installed Abiquo. If you configured one of the eth addresses using DHCP, it has to deliver a hostname and gateway address. To verify this is properly configured, access the /etc/hosts file and check if your hostname appears in it; if not, add it.
Attempting to connect to MySQL or MariaDB fails with message: "Error 1043: Bad handshake" when trying to connect with support for pre-4.1 hashed password.
The parameter "old_passwords" must be set to "0" in "/etc/my.cnf" file.
If compatibility with pre-4.1 hashed passwords is needed in your environment a downgrade to version 5.1.56 is the solution until the bug fix is shipped with a newer version.
When creating a new Physical Data Center, Abiquo gives an error that some of the remote services aren't properly configured although every check is green.
NetApp credentials properties were changed to GUI properties in v2.0. Since v2.0, NetApp credentials are entered when creating or editing the storage device in Infrastructure view in the Abiquo GUI. The NetApp credentials properties in abiquo.properties will not be read.
Check that the NFS repository is correctly configured.
Disable the check for mounted repositories by setting the property "abiquo.appliancemanager.checkMountedRepository" to false on /opt/abiquo/config/abiquo.properties. By default this property is set to true.
An external volume is not attached or operational when used in managed storage, generic iSCSI storage volumes or persistent virtual machines, but there is no notification in the GUI or API.
If a volume has been removed or replaced in the storage device, Abiquo may try to attach a volume that does not exist or is a completely different to one previously configured. The volume will not be attached or operational, but there will be no notification in the GUI or API.
Abiquo avoids performing a full HBA rescan of storage on ESX or ESXi for performance reasons. Instead it checks for a raw device mapping for a given IQN and LUN. If the raw device mapping is not correct, this problem may occur.
This problem can be resolved by manually performing a full HBA rescan of all ESX or ESXi hosts that had raw device mappings for the devices involved.
In the VMware vSphere or VI Client you can rescan all HBAs by clicking the Configuration tab, then clicking Storage Adapters. Next, click the Rescan link and OK to continue.
VCenter is managing the ESXi machine. There is already an existing VM with the same name. VCenter renames the new VM but then Abiquo cannot find it.
Remove the orphaned VM with the same name.
When deploying, you receive the notification: "Not enough resources available".
The problem is there are not physical machines with enough resources (HD, CPU, RAM) to deploy the virtual machine.
There are 2 possible solutions:
Check for the existence of a message like "command not found" in the log.
The V2V or Remote Services machine or the target Hypervisor (if the error is at deploy time) does not have the iSCSI client installed. Check that the machine has the open-iscsi package installed.
Check for a message like "could not send targets"
Communication between machines may be broken. A network error could have occurred because of a firewall, a timeout, etc. The iSCSI server may be down (stopped or broken). Check that the iSCSI service is up and running. Then check that you can telnet from the BPM machine to the storage machine, to the host port.
For more information, see storage servers.
If you suspect that the client service is down, run this command with one of the options on server:
To check if services are enabled:
To enable services in Nexenta (remember that you should log in to Nexenta as admin. Then change privileges by using su (and not su-))
Delete volumes to free space in the storage pool.
An error occurred when calling the deploy operation in a Hyper-V machine. This error appears in the log:
Although the URI is correct, Hyper-V accesses the filesystem using Samba. In Samba, the directory is aliased as vm_repository. To change this directory go to the server, /opt/abiquo/config (remember that this path could be in a chroot system). Then edit the abiquo.properties file and enter the following property containing the IP address of the CIFS server:
and restart the Tomcat server.
Check the smb.conf file is correctly configured. This file is configured during installation. For more information, see VM repository folder.
The physical machine does not have the right port. Change it to the correct one. You can check this port in the hypervisortype table in the DB.
When deploying, notification in tracer: "SR_BACKEND_FAILURE_47The SR is not available [opterr=no such directory /var/run/sr-mount/fe1a9f24-3699-a02d-e226-dfc59db6b596]" .
NFS mount point is unreachable by XenServer. Connect to XenCenter and delete the Abiquo repositories (ONLY the Abiquo repositories) of the XenServer machines that are failing. To delete them you must Detach and Forget.
Once deleted, try to deploy again. The Abiquo repository should appear again in XenServer and the VM should deploy successfully.
