Abstract
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.
