QEMU can emulate the paravirtual sPAPR interface with the following peripherals: PCI bridge, for access to VirtIO devices, VGA-compatible graphics, USB, etc. Virtual I/O network adapter, SCSI controller, and serial interface; sPAPR non-volatile RAM; On the sPAPR target, another Open-Firmware-compatible BIOS is used, called SLOF.
Supported guest OS drivers Method of operation Typical use Speed relative to host OS Commercial support available Containers, or Zones Yes, over 500-way on current systems No Uses native device drivers Operating system-level virtualization: Server consolidation with workload isolation, single workload containment, hosting, dev/test/prod Near native
The system emulates hardware via a patched QEMU "device manager" (qemu-dm) daemon running as a backend in dom0. This means that the virtualized machines see an emulated version of a fairly basic PC. In a performance-critical environment, PV-on-HVM disk and network drivers are used during the normal guest operation, so that the emulated PC ...
GPU virtualization refers to technologies that allow the use of a GPU to accelerate graphics or GPGPU applications running on a virtual machine.GPU virtualization is used in various applications such as desktop virtualization, [1] cloud gaming [2] and computational science (e.g. hydrodynamics simulations).
The host in this article is the system running the emulator, and the guest is the system being emulated. The list is organized by guest operating system (the system being emulated), grouped by word length. Each section contains a list of emulators capable of emulating the specified guest, details of the range of guest systems able to be ...
The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]
PCI Firmware Specification; SeaBIOS as a Compatibility Support Module (CSM) for Unified Extensible Firmware Interface (UEFI) and Open Virtual Machine Firmware (OVMF) Virtual machine host notification of paravirtualized guests which panic via the pvpanic driver; A patch exists to load the SLIC table from a licensed OEM Windows BIOS. [3] Trusted ...
The QEMU maintainers merged support for providing SPICE remote desktop capabilities for all QEMU virtual machines in March 2010. The QEMU binary links to the spice-server library to provide this capability and implements the QXL paravirtualized framebuffer device to enable the guest OS to take advantage of the performance benefits the SPICE ...
