Embodiment Construction
[0040] Such as figure 2 As shown, a virtual machine system that performs input and output (I / O) virtualization outside a virtual machine monitor (VMM), a processor platform based on hardware-assisted virtualization technology:
[0041] Guest virtual machine A generates an I / O request, which is captured by the VMM, and the VMM allocates IOVM 1 to process the I / O request according to the type of the I / O request and related information.
[0042] Another I / O request generated by guest virtual machine A is captured by the VMM, and the VMM allocates IOVM 2 to process the I / O request according to the type and related information of the I / O request.
[0043] The I / O request generated by guest virtual machine B is captured by the VMM, and the VMM allocates IOVM 2 to process the I / O request according to the type and related information of the I / O request.
[0044] Multiple I / O requests from a guest virtual machine can be handled by one or more IOVMs. An I / O request from client A and ...
