[libvirt] [PATCH 1/2] esx: Do not crash SetAutoStart by double free
SetAutoStart method cannot free virtualMachine using
esxVI_ObjectContent_Free, since:
esxVI_HostAutoStartManagerConfig_Free
-> esxVI_AutoStartPowerInfo_Free
-> esxVI_ManagedObjectReference_Free(item->key);
item->key, in this context, is virtualMachine->obj, so calling
esxVI_ObjectContent_Free creates a double free, becasuse
esxVI_ObjectContent_Free also calls esxVI_ManagedObjectReference_Free(&item->obj).
Removing the esxVI_ObjectContent_Free from SetAutoStart fixes this
problem.
