摘要： Remote memory can be used for a number idle pages located on a virtual machine. A number of idle pages can be sent to the remote memory according to a placement policy, where the placement policy can include a number of weighting factors. A hypervisor on a computing device can record a local size and a remote page fault frequency of the number of virtual machines. The hypervisor can scan local memory to determine the number of idle pages and a number of idle virtual machines. The number of idle pages, including a page map and a remote address destination for each idle page, can be sent to the remote memory by the hypervisor. The number of virtual machines can be analyzed to determine a per-virtual machine local memory allocation.

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.
摘要翻译：在一个或多个计算设备上实现第一虚拟机以产生对硬件设备的输入/输出（I / O）请求。还在计算设备上实现第二虚拟机。机制是在直接模式和间接模式之间切换，而不在硬件设备的第一上下文和第二上下文之间切换。在直接模式下，第一个虚拟机产生的I / O请求将被发送到硬件设备，而不会被重定向到第二个虚拟机。在间接模式下，第一个虚拟机产生的I / O请求将被重定向到第二个虚拟机进行处理。第二个虚拟机是在处理重定向到第二个虚拟机的I / O请求后，将I / O请求发送到硬件设备。

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.
