   1 # q35 - Emulated guest (graphical console)
   2 # =========================================================
   3 #
   4 # Usage:
   5 #
   6 #   $ qemu-system-x86_64 \
   7 #     -nodefaults \
   8 #     -readconfig q35-emulated.cfg
   9 #
  10 # You will probably need to tweak the lines marked as
  11 # CHANGE ME before being able to use this configuration!
  12 #
  13 # The guest will have a selection of emulated devices that
  14 # closely resembles that of a physical machine, and will be
  15 # accessed through a graphical console.
  16 #
  17 # ---------------------------------------------------------
  18 #
  19 # Using -nodefaults is required to have full control over
  20 # the virtual hardware: when it's specified, QEMU will
  21 # populate the board with only the builtin peripherals
  22 # plus a small selection of core PCI devices and
  23 # controllers; the user will then have to explicitly add
  24 # further devices.
  25 #
  26 # The core PCI devices show up in the guest as:
  27 #
  28 #   00:00.0 Host bridge
  29 #   00:1f.0 ISA bridge / LPC
  30 #   00:1f.2 SATA (AHCI) controller
  31 #   00:1f.3 SMBus controller
  32 #
  33 # This configuration file adds a number of devices that
  34 # are pretty much guaranteed to be present in every single
  35 # physical machine based on q35, more specifically:
  36 #
  37 #   00:01.0 VGA compatible controller
  38 #   00:19.0 Ethernet controller
  39 #   00:1a.* USB controller (#2)
  40 #   00:1b.0 Audio device
  41 #   00:1c.* PCI bridge (PCI Express Root Ports)
  42 #   00:1d.* USB Controller (#1)
  43 #   00:1e.0 PCI bridge (legacy PCI bridge)
  44 #
  45 # More information about these devices is available below.

  51 # We use the q35 machine type and enable KVM acceleration
  52 # for better performance.
  53 #
  54 # Using less than 1 GiB of memory is probably not going to
  55 # yield good performance in the guest, and might even lead
  56 # to obscure boot issues in some cases.
  57 #
  58 # Unfortunately, there is no way to configure the CPU model
  59 # in this file, so it will have to be provided on the
  60 # command line.
