1 .. _QEMU-PC-System-emulator:
3 x86 (PC) System emulator
4 ------------------------
11 The QEMU PC System emulator simulates the following peripherals:
13 - i440FX host PCI bridge and PIIX3 PCI to ISA bridge
15 - Cirrus CLGD 5446 PCI VGA card or dummy VGA card with Bochs VESA
16 extensions (hardware level, including all non standard modes).
18 - PS/2 mouse and keyboard
20 - 2 PCI IDE interfaces with hard disk and CD-ROM support
24 - PCI and ISA network adapters
28 - IPMI BMC, either and internal or external one
30 - Creative SoundBlaster 16 sound card
32 - ENSONIQ AudioPCI ES1370 sound card
34 - Intel 82801AA AC97 Audio compatible sound card
36 - Intel HD Audio Controller and HDA codec
38 - Adlib (OPL2) - Yamaha YM3812 compatible chip
40 - Gravis Ultrasound GF1 sound card
42 - CS4231A compatible sound card
44 - PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1
47 SMP is supported with up to 255 CPUs.
49 QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL
52 QEMU uses YM3812 emulation by Tatsuyuki Satoh.
54 QEMU uses GUS emulation (GUSEMU32 http://www.deinmeister.de/gusemu/) by
57 Note that, by default, GUS shares IRQ(7) with parallel ports and so QEMU
58 must be told to not have parallel ports to have working GUS.
62 |qemu_system_x86| dos.img -soundhw gus -parallel none
68 |qemu_system_x86| dos.img -device gus,irq=5
70 Or some other unclaimed IRQ.
72 CS4231A is the chip used in Windows Sound System and GUSMAX products

81 On x86_64 hosts, the default set of CPU features enabled by the KVM
82 accelerator require the host to be running Linux v4.5 or newer. Red Hat
83 Enterprise Linux 7 is also supported, since the required
84 functionality was backported.
