> Platform packages installed and properly configured.
> Reporter: Rafael Weingartner
> Priority: Critical

>
>
> 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.
