    摘要： According to an example, a method for virtual machine (VM) data packet encapsulation and decapsulation may include receiving a data packet including a media access control (MAC) header and an internet protocol (IP) header. The method may further include encapsulating, by a processor, the received data packet to include an encapsulating MAC header, an encapsulating IP header, a VM MAC header with a same content as the MAC header of the received data packet, and a VM IP header with a same content as the IP header of the received data packet.

    摘要： According to an example, a method for bandwidth guarantee and work conservation includes determining virtual machine (VM) bandwidth guarantees assigned to VMs in a network including a source VM that communicates with destination VMs. The method further includes assigning minimum bandwidth guarantees to communications between the source VM with the destination VMs by dividing a VM bandwidth guarantee assigned to the source VM between the destination VMs based on active VM-to-VM communications between the source VM and the destination VMs. The method also includes allocating, by a processor, spare bandwidth capacity in the network to a communication between the source VM and a destination VM based on the assigned minimum bandwidth guarantees.

    摘要： Example methods, apparatus, and articles of manufacture to share memory spaces for access by hardware and software in a virtual machine environment are disclosed. A disclosed example method involves enabling a sharing of a memory page of a source domain executing on a first virtual machine with a destination domain executing on a second virtual machine. The example method also involves mapping the memory page to an address space of the destination domain and adding an address translation entry for the memory page in a table. In addition, the example method involves sharing the memory page with a hardware device for direct memory access of the memory page by the hardware device.

    摘要： A first virtual machine is implemented on one or more computing devices to generate input/output (I/O) requests to a hardware device. A second virtual machine is also implemented on the computing devices. A mechanism is to switch between a direct mode and an indirect mode without switching between a first context and a second context of the hardware device. In the direct mode, the I/O requests generated by the first virtual machine are to be sent to the hardware device without being redirected to the second virtual machine. In the indirect mode, the I/O requests generated by the first virtual machine are to be redirected to the second virtual machine for processing. The second virtual machine is to, after processing the I/O requests redirected to the second virtual machine, send the I/O requests to the hardware device.
