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
Review the NFS configuration in the file at
/opt/abiquo/config/abiquo.properties.Restart the Tomcat server
service abiquo-tomcat restart.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.
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.repositoryLocationof127.0.0.1:/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
Hyper-V
Hyper-V does not deploy images
Symptoms
An error occurred when calling the deploy operation in a Hyper-V machine. This error appears in the log:

org.jinterop.dcom.common.JIException: An error was occurred when calling an operation in a Hyper-V machine
Solution
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:
abiquo.virtualfactory.hyperv.repositoryLocation = //<SERVER_IP>/vm_repository/
and restart the Tomcat server.
Hyper-V does not create an instance
Symptoms
Only happens in Hyper-V

Solution
Check the smb.conf file is correctly configured. This file is configured during installation. For more information, see VM repository folder.
