> 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 del=
eted.
> There will happen a null pointer exception in "com.cloud.vm.VirtualMachin=
eManagerImpl.orchestrateStart":
> =E2=80=9C858 -        if (volTemplateId !=3D null && volTemplateId.longVa=
lue() !=3D template.getId())=E2=80=9D
> The object, =E2=80=9Ctemplate=E2=80=9D is going to be null, because in:
> =E2=80=9C811 -  VirtualMachineTemplate template =3D _entityMgr.findById(V=
irtualMachineTemplate.class, vm.getTemplateId());=E2=80=9D
> 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.
