VIRTUAL MACHINE EXIT ANALYZER

摘要

Technologies are generally described for systems, devices and methods effective to implement a virtual machine exit analyzer. A virtual machine handler may receive a request that includes an instruction. The instruction may include a port and a data block identifier. The virtual machine handler may generate a modified request. The modified request may include the port, a block portion identifier and an identification of a comparator. The virtual machine handler may send values identified by the block portion identifier to the comparator. The virtual machine handler may receive an exit indicator from the comparator that indicates whether the virtual machine should exit the core.

1. A method to determine whether a virtual machine should exit a core, the method comprising:
receiving an initial request that includes an instruction to receive data at, or output data from, a port of a processor, wherein the instruction includes an identification of the port and a data block identifier; generating a modified request from the initial request, where the modified request includes the identification of the port, a block portion identifier, and an identification of a comparator; sending values identified by the block portion identifier to the comparator; and receiving an exit indicator from the comparator in response to sending the values identified by the block portion identifier, wherein the exit indicator indicates whether the virtual machine should exit the core.
