Abstract:
A system and methods are disclosed for detecting inconsistent instances of a system table in a virtualized computer system. In accordance with one embodiment, a processing device decompiles a first binary representing a first instance of a system table, to obtain a first string of symbols. The processing device also decompiles a second binary representing a second instance of the system table that is associated with guest firmware of a first virtual machine, to obtain a second string of symbols. When there is a difference between the first string of symbols and the second string of symbols and the difference is unrelated to a compiler version and a temporary variable name, a signal indicating an inconsistency between the first instance and the second instance is generated.
