Abstract: A virtual machine control method and a virtual machine having the dual objectives of utilizing NIC on a virtual machine that creates sub-virtual machines operated by a VMM on virtual machines generated by a hypervisor to avoid software copying by the VMM and to prevent band deterioration during live migration or adding sub-virtual machines. In a virtual machine operating plural virtualization software on a physical machine including a CPU, memory, and multi-queue NIC; a virtual multi-queue NIC is loaded in the virtual machine, for virtual queues included in the virtual multi-queue NIC, physical queues configuring the multi-queue NIC are assigned to virtual queues where usage has started, and the physical queues are allowed direct access to the virtual machine memory.
