Structs

The interface guest_vm_arch.h defines the following structs.

Struct vm_vcpu

Structure representing x86 specific vm properties

Elements:

• vmexit_handler {vmexit_handler_ptr}: Set of exit handler hooks
• vmcall_handlers {vmcall_handler_t *}: Set of registered vmcall handlers
• vmcall_num_handler {unsigned int}: Total number of registered vmcall handlers
• guest_pd {uintptr_t}: Guest physical address of where we built the vm's page directory
• unhandled_ioport_callback {unhandled_ioport_callback_fn}: A callback for processing unhandled ioport faults
• unhandled_ioport_callback_cookie {void *}: A cookie to supply to the ioport callback
• ioport_list {vm_io_port_list_t}: List of registered ioport handlers
• i8259_gs {i8259_t *}: PIC machine state
