Summary: Unable to live migrate an instance to another host in a
cluster from which the template has been deleted
Key: CLOUDSTACK-7839
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7839
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Template
Affects Versions: Future, 4.3.0, 4.4.0, 4.5.0, 4.3.1, 4.4.1, 4.6.0
Reporter: Joris van Lieshout
Priority: Critical
ACS throws an null pointer exception when you try to live migrate an instance
to another host in a cluster and the template of that instance has been deleted.
I have pasted the exception below.
Steps to reproduce the issue:
1. create an instance from iso
2. stop the instance
3. create a template from the root volume
4. create a new instance from that template
5. leave the instance running
6. delete the template
7. try the live migrate the instance to another host in the cluster
The migrate button in the web interface will not respond.
The exception below can be found in the management-server log
