In fixed pass-through or GPU pass-through (a special case of PCI pass-through), a GPU is accessed directly by a single virtual machine exclusively and permanently. This technique achieves 96–100% of native performance [ 3 ] and high fidelity, [ 1 ] but the acceleration provided by the GPU cannot be shared between multiple virtual machines.
The virtual or physical functions available to the hypervisor or guest operating system depend on the PCIe device. [3] The SR-IOV allows different virtual machines (VMs) in a virtual environment to share a single PCI Express hardware interface. In contrast, MR-IOV allows I/O PCI Express to share resources among different VMs on different ...
Fixes a bug with starting virtual machines on OS X 10.7.4. [33] 4.0 September 14, 2011 Run Lion, Lion Server, Snow Leopard, Snow Leopard Server, and Leopard Server in virtual machines, up to 2.5x faster 3D graphics, add Windows programs to Launchpad, view in full screen, or in Mission Control. [34] 4.0.1 September 14, 2011
Choice of GPU: All RemoteFX features can be used with either a software-emulated GPU, which is available by default in all virtual machines and session hosts, or they can benefit from hardware acceleration when a physical video card is placed in the server and the RemoteFX vGPU is enabled. [11] In addition, the following components were updated:
Platform virtualization software, specifically emulators and hypervisors, are software packages that emulate the whole physical computer machine, often providing multiple virtual machines on one physical platform. The table below compares basic information about platform virtualization hypervisors.
Sandboxed Graphics: Virtual machine security is enhanced by removing graphics render from vmx and running it as a separate sandbox process. USB 3.1 Controller Support: The virtual machines virtual XHCI controller is changed from USB 3.0 to USB 3.1 to support 10 Gbit/s. Larger VMs: 32 virtual CPUs (host and guest OS must both support this number)
AMDgpu is an open source device driver for the Linux operating system developed by AMD to support its Radeon lineup of graphics cards (GPUs). It was announced in 2014 as the successor to the previous radeon device driver as part of AMD's new "unified" driver strategy, [3] and was released on April 20, 2015.
Resizing of disk image formats from Oracle, VDI (VirtualBox disk image), and Microsoft, VHD (Virtual PC hard disk) 4.1 Jul 19, 2011: Windows Aero support (experimental) Virtual machine cloning; 4.2 Sep 13, 2012: Virtual machine groups – allows management of a group of virtual machines as a single unit (power them on or off, take snapshots, etc.)
