# 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
# edk2-aarch64 (pkg)

#
# If you're running the guest on a remote, potentially
# headless host, you will probably want to append something
