# mach-virt - VirtIO guest (graphical console)

# =========================================================

#

# Usage:

#

#   $ qemu-system-aarch64 \

#     -nodefaults \

#     -readconfig mach-virt-graphical.cfg \

#     -cpu host

#

# 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 VirtIO devices

# tailored towards optimal performance with modern guests,

# 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,

# such as the PL011 UART, plus a PCI Express Root Bus; the

# user will then have to explicitly add further devices.

#

# The PCI Express Root Bus shows up in the guest as:

#

#   00:00.0 Host bridge

#

# This configuration file adds a number of other useful

# devices, more specifically:

#

#   00:01.0 Display controller

#   00.1c.* PCI bridge (PCI Express Root Ports)

#   01:00.0 SCSI storage controller

#   02:00.0 Ethernet controller

#   03:00.0 USB controller

#

# More information about these devices is available below.

# Machine options

# =========================================================

#

# We use the virt 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, but we can configure the guest to use the

# same GIC version as the host.

# Firmware configuration

# =========================================================

#

# There are two parts to the firmware: a read-only image

# containing the executable code, which is shared between

# guests, and a read/write variable store that is owned

# by one specific guest, exclusively, and is used to

# record information such as the UEFI boot order.

#

# For any new guest, its permanent, private variable store

# should initially be copied from the template file

# provided along with the firmware binary.

#

# Depending on the OS distribution you're using on the

# host, the name of the package containing the firmware

# binary and variable store template, as well as the paths

# to the files themselves, will be different. For example:

#

# Fedora

# SATA storage

# =========================================================

#

# An implicit SATA controller is created automatically for

# every single q35 guest; here we create a disk, backed by

# a qcow2 disk image on the host's filesystem, and attach

# it to that controller so that the guest can use it.

#

# We also create an optical disk, mostly for installation

# purposes: once the guest OS has been succesfully

# installed, the guest will no longer boot from optical

# media. If you don't want, or no longer want, to have an

# optical disk in the guest you can safely comment out

# all relevant sections below.
