Instead of having a single sample configuration file,
we now have several:
* q35-emulated.cfg documents the default devices QEMU
adds to a q35 guest and the additional devices that
are pretty much guaranteed to be present in a
physical q35-based machine;
* q35-virtio-graphical.cfg can be used to start a
fully-featured (USB, graphical console, audio, etc.)
guest that uses VirtIO instead of emulated devices;
* q35-virtio-serial.cfg is similar but has a minimal
set of devices and uses the serial console.
All configuration files are fully commented and neatly
organized.

# 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.

|
|
# =========================================================
|
|
#
|
|
# 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.
