Open source machine emulator and virtualizer

The QEMU Project includes the QEMU open source machine emulator and virtualizer and also acts as an umbrella organization for the KVM Linux kernel module and Jailhouse partitioning hypervisor. When used as a machine emulator, QEMU can run operating systems and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance. When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, ARM, server and embedded PowerPC, and S390 guests.

    Generic PCIE-PCI bridge
    Nowadays QEMU doesn't have any PCIE-PCI bridge except DMI-PCI i82801b11 bridge, but as DMI is a proprietary Intel bus, it can be used only on x86...

    Hypervisor.framework Support for QEMU
    The idea of the project is to add support for macOS’s native hypervisor through the Hypervisor.framework API. This API exposes to user applications...

    Implementing I/O throttling and write notifiers into filter Block Drivers
    I/O throttling is currently hard-coded in QEMU. A request is checked for throttling directly in block-backend.c instead of having a filter driver...

    Virgl Windows driver
    3D acceleration is non-existent on Windows guests. The goal for this project is to bring a support for OpenGL. For the host part, we will use Virgl,...
