A method of an aspect includes receiving an indication of an attempt by a virtual machine to modify a paging structure identification storage location to have a given value. It is determined that the given value matches at least one of a set of one or more blacklist values. The attempt by the virtual machine to modify the paging structure identification storage location to have the given value is trapped to a virtual machine monitor. Other methods, apparatus, and systems are also disclosed.

Processors, methods, and systems to enforce blacklisted paging structure indication values

Methods and apparatus are disclosed to capture error conditions in lightweight virtual machine managers. A disclosed example method includes defining a shared memory structure between the VMM and a virtual machine (VM), when the VM is spawned by the VMM, installing an abort handler on the VM associated with a vector value, in response to detecting an error, transferring VMM state information to the shared memory structure, and invoking the abort handler on the VM to transfer contents of the shared memory structure to a non-volatile memory.
