----------------------------------------------
Summary: Null pointer exception when starting a VM that had its
template deleted
Key: CLOUDSTACK-6945
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6945
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.3.0
Environment: Hosts are Debian 7.4.0 with Xen hypervisor e Xen Cloud
Platform packages installed and properly configured.
Reporter: Rafael Weingartner
Priority: Blocker
Fix For: 4.3.1
It seems that you have a bug in CS 4.3.0(and probably previous versions?) when
starting a machine that was created from a template that has been deleted.
There will happen a null pointer exception in
"com.cloud.vm.VirtualMachineManagerImpl.orchestrateStart":
“858 - if (volTemplateId != null && volTemplateId.longValue() !=
template.getId())”
The object, “template” is going to be null, because in:
“811 - VirtualMachineTemplate template =
_entityMgr.findById(VirtualMachineTemplate.class, vm.getTemplateId());”
The findById, will add a where clause, looking for template that have the
column removed that is null, therefore It will return a null object.
