Troubleshooting configuration problems

This document provides a list of quick answers to issues caused by incorrect configuration.

Events problems

Only events related to roles are displayed

Symptoms

No events except those related to roles are displayed.

Solution

Verify that you correctly configured the network when you installed Abiquo. If you configured one of the NICs 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.

Infrastructure problems

Remote services error despite green lights on checks

Symptoms

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.

Solution

1. Review the NFS configuration in the file at /opt/abiquo/config/abiquo.properties.

2. Restart the Tomcat server service abiquo-tomcat restart.

3. Check there is a file in the directory /opt/vm_repository/ named .abiquo_repository.

Catalogue problems

Downloaded VM templates do not appear in the catalogue

Symptoms

• The server has been installed or restarted recently.

• Images appear as downloaded in the remote repository.

• No images appear in the catalogue.

Solution

Check that the NFS repository is correctly configured.

• See VM repository folder and Troubleshooting NFS server configuration in Abiquo

Appliance manager problems

Appliance manager is not working

Symptoms

• Appliance manager is not working

• NFS server is located on the same machine as the remote services.

• Error message: "Can't validate abiquo.appliancemanager.repositoryLocation of 127.0.0.1:/opt/vm_repository. It's a local repository"

Solution

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.

Virtual datacenter problems

Not enough resources available

Symptoms

When deploying, you receive the notification: "Not enough resources available".

Solution

The problem is there are not physical machines with enough resources (HD, CPU, RAM) to deploy the VM.
There are 2 possible solutions:

• Undeploy some VMs

• Make sure you have a physical machine with enough resources to be able to deploy

• Oversubscribe your physical machines with an allocation rule for load level compute resources
