 # q35 - Emulated guest (graphical console)
 # =========================================================
 #
 # Usage:
 #
 #   $ qemu-system-x86_64 \
 #     -nodefaults \
 #     -readconfig q35-emulated.cfg
 #
 # You will probably need to tweak the lines marked as
 # CHANGE ME before being able to use this configuration!
 #
 # The guest will have a selection of emulated devices that
 # closely resembles that of a physical machine, and will be
 # accessed through a graphical console.
 #
 # ---------------------------------------------------------
 #
 # Using -nodefaults is required to have full control over
 # the virtual hardware: when it's specified, QEMU will
 # populate the board with only the builtin peripherals
 # plus a small selection of core PCI devices and
 # controllers; the user will then have to explicitly add
 # further devices.
 #
 # The core PCI devices show up in the guest as:
 #
 #   00:00.0 Host bridge
 #   00:1f.0 ISA bridge / LPC
 #   00:1f.2 SATA (AHCI) controller
 #   00:1f.3 SMBus controller
 #
 # This configuration file adds a number of devices that
 # are pretty much guaranteed to be present in every single
 # physical machine based on q35, more specifically:
 #
 #   00:01.0 VGA compatible controller
 #   00:19.0 Ethernet controller
 #   00:1a.* USB controller (#2)
 #   00:1b.0 Audio device
 #   00:1c.* PCI bridge (PCI Express Root Ports)
 #   00:1d.* USB Controller (#1)
 #   00:1e.0 PCI bridge (legacy PCI bridge)
 #
 # More information about these devices is available below.


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