Hi, Keir, This patch is to fix the problem of Linux guest installation failure and Windows 2000 boot failure.       In the early code, we use vmx_vmexit_handler() -> vmx_io_instruction() function to emulate I/O instructions. But now, we use vmx_vmexit_handler() -> handle_mmio -> hvm_emulate_one() -> x86_emulate() to emulate I/O instructions. Also nowadays, the realmode

...rouble you again. I want to emulate instruction "push %ebp" in Xen. I found the function emulate_privilege_op does not satisfy this requirement. Then I resort to x86_emulate. I construct the x86_emulate_ctxt and reuse the "ptwr_emulate_ops". code like this: extern const struct x86_emulate_ops ptwr_emulate_ops; in do_general_protection { .... struct x86_emulate_ctxt ctxt; ctxt.regs = regs; ctxt.force_writeback = 1; // 0 is the same ctxt.addr_size = 32; ctxt.sp_size = 32; ret = x86_emulate(&ctxt, &ptwr_emulate_ops); ... } the error message is: (XEN) mm.c:5235:d0 ptwr_emu...

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
